<abstract>
<p>The continued growth of polar tourism is causing increasing concerns about its potential environmental effects, invigorating the current discourse about tourism&#x00027;s role in the sustainable future of the Polar Regions. These concerns are often met with the industry&#x00027;s narratives on purported positive impacts of polar tourists who would become ambassadors, stewards or advocates. However, the extent to, and the ways in which these three seemingly interchangeable &#x02018;ambassador&#x00027; terms have been used or examined in the scientific literature are largely unknown. To address this gap, we traced the definitions of these terms and identified 16 peer-reviewed studies that incorporated the terms in two types of study design: (1) discussing the terms in the context of investigating relationship and influential factors of tourists&#x00027; motivations, experiences, behavior intentions, and behavior; and (2) examining the terms as ethical imperatives or normative concepts. Results of this scoping review provides a clearer picture of how the &#x0201C;ambassador&#x0201D; terms are defined and utilized in polar tourism research, and points to the needs for further understanding, conceptualization, and operationalization of the related concepts beyond focusing on tourists themselves as ambassadors.</p></abstract>

<title>1 Introduction</title>
<p>Our society is living in the Anthropocene, an era in which human activities are making lasting impacts across the globe, including their contributions to the climate crisis (Tempelhoff, <xref ref-type="bibr" rid="B54">2021</xref>). Tourism is one of the major contemporary human activities that can have both positive and negative economic, environmental, and social impacts (McCool and Bosak, <xref ref-type="bibr" rid="B37">2016</xref>; Leung et al., <xref ref-type="bibr" rid="B33">2018</xref>). Tourism impacts are of particular concern in the highly sensitive and increasingly visited polar regions of the Arctic North: Canada, the Nordic Countries (Denmark, Finland, Iceland, Norway, Sweden, Greenland) (J&#x000F3;hannesson et al., <xref ref-type="bibr" rid="B29">2022</xref>; The Nordic Council and the Nordic Council of Ministers, <xref ref-type="bibr" rid="B55">2023</xref>), Russia, and USA-Alaska, and the South: Antarctica (Hall and Saarinen, <xref ref-type="bibr" rid="B20">2010</xref>; Stewart et al., <xref ref-type="bibr" rid="B52">2010</xref>; Vila et al., <xref ref-type="bibr" rid="B61">2016</xref>, p. 451).</p>
<p>Human impacts within the polar regions, including those associated with tourism activities, are often cumulative, both on local, ecosystem-specific vegetation and wildlife and globally, contributing to carbon emissions that are linked to the increased pace at which the glaciers, ice caps, and sea ice in these regions melt (Dawson et al., <xref ref-type="bibr" rid="B13">2007</xref>). Due to the remote nature of these destinations, tourists&#x00027; often travel on long-haul flights over the standard international round-trip distance of 4,100 km, releasing about 3.2 tons of carbon dioxide (CO<sub>2</sub>) per passenger, per flight (Amelung and Lamers, <xref ref-type="bibr" rid="B5">2007</xref>). Additionally, visiting polar regions generally involves cruising for long periods of time, a week or more, which releases the &#x0201C;highest per capita CO<sub>2</sub> emissions in tourism&#x0201D; (Amelung and Lamers, <xref ref-type="bibr" rid="B5">2007</xref>; Eijgelaar et al., <xref ref-type="bibr" rid="B15">2010</xref>, p. 340; Farreny et al., <xref ref-type="bibr" rid="B16">2011</xref>). Black carbon and other air pollutants that are released by vessels, airplanes, helicopters, diesel power plants, and generators can accelerate melting of ice by reducing the albedo of snow-covered, polar environments (Cordero et al., <xref ref-type="bibr" rid="B12">2022</xref>, p. 2).</p>
<p>Polar tourism has found itself in a positive feedback loop with climate change impacts. The rise of polar tourism can be attributed to several factors, including decreased airfare costs, more information available to prospective tourists, and a trend of &#x0201C;last chance tourism&#x0201D; (Snyder, <xref ref-type="bibr" rid="B48">2007</xref>; Vila et al., <xref ref-type="bibr" rid="B61">2016</xref>). A motivation consistently cited in the polar tourism literature that references visiting a climate-change vulnerable location before it drastically changes or disappears (Abrahams et al., <xref ref-type="bibr" rid="B2">2022</xref>). Visitation data to the Arctic is not centrally collected, making accurate counts difficult. The following estimates come pre-COVID from 2017 to 2019 from Maher et al. (<xref ref-type="bibr" rid="B34">2021</xref>). The most visitation was reported among the Nordic countries, Finland with 3 million in 2019, Sweden 2.9 million in 2018, and Norway 2.7 million in 2017, with 158,000 of those visitors in Svalbard in 2018. Alaska recorded 2.4 million in 2019 (Alaska Department of Commerce, Community, and Economic Development, <xref ref-type="bibr" rid="B3">2022</xref>) and Iceland with 2.2 million in 2017. Whereas, destinations like Canada had around 500,000 and Greenland only 90,000 in 2017 (Maher et al., <xref ref-type="bibr" rid="B34">2021</xref>). The first commercial tourism in Antarctica may have officially begun in the early 1960s, but substantial growth in visitation occurred in the mid-90&#x00027;s, early 2000s, and is now expected again, post-pandemic (IAATO, <xref ref-type="bibr" rid="B26">2022</xref>). At the beginning of the millennium, an estimated 12,248 visitors traveled to Antarctica (IAATO, <xref ref-type="bibr" rid="B23">2001</xref>). During the 2019&#x02013;20 season, 74,401 tourists traveled to the continent by a combination of air-cruises and cruises (IAATO, <xref ref-type="bibr" rid="B25">2020b</xref>). After a two-year halt due to the COVID-19 pandemic, Antarctic tourism is returning in full force, reaching 104,897 visitors in 2022&#x02013;23 season (IAATO, <xref ref-type="bibr" rid="B28">2023b</xref>). How tens of thousands or even more tourists interact with these environments is an important factor in managing the environmental impacts of tourism and generating long-lasting awareness among tourists.</p>
<p>Tourism activities in the Arctic regions span multiple sovereign nations that all have their own policies and regulations (Taylor et al., <xref ref-type="bibr" rid="B53">2020</xref>). The fragmentation of tourism management in the Arctic means that each country is individually responsible for managing tourism and not only its environmental, but social impacts on the local and indigenous communities, additional challenges that Antarctica does not have (Kerber, <xref ref-type="bibr" rid="B30">2022</xref>). In contrast, Antarctica, a singular land without a resident population or a sovereign body, relegates governance decisions to the Antarctic Treaty Consultative Parties (ATCPs) and their instruments, especially the Protocol on Environmental Protection to the Antarctic Treaty, or the Madrid Protocol (Cajiao et al., <xref ref-type="bibr" rid="B9">2021</xref>). Though directives for tourism regulation are not directly laid out in the Treaty itself, the ATCPs can choose to implement binding or non-binding, tourism policy through national legislation (Abdullah et al., <xref ref-type="bibr" rid="B1">2015</xref>). In the absence of sweeping policy, the International Association of Antarctica Tour Operators (IAATO) formed to self-regulate the industry through guidelines (Verbitsky, <xref ref-type="bibr" rid="B60">2013</xref>). IAATO formed in 1991 to &#x0201C;advocate, promote, and practice safe and environmentally responsible, private-sector travel in Antarctica&#x0201D; (IAATO, <xref ref-type="bibr" rid="B24">2020a</xref>). The complex nature of tourism in the polar regions has sparked debate and curiosity among researchers and industry to determine how this specialized form of tourism can contribute to the conservation and protection of these places.</p>
<p>Polar tourists are often provided with unique opportunities to connect to the environment through immersive educational experiences and first-hand interactions with wilderness and wildlife. These experiences and education provided either on-site or on cruises can influence a tourist&#x00027;s intention to behave in a way that benefits the environment, better known as their pro-environmental behavior intentions (Kollmuss and Agyeman, <xref ref-type="bibr" rid="B31">2002</xref>). Educational and interpretive experiences have long been utilized to facilitate visitor behavior change, especially in protected area settings (Ham and Krumpe, <xref ref-type="bibr" rid="B21">1996</xref>; Larson et al., <xref ref-type="bibr" rid="B32">2015</xref>; Backman et al., <xref ref-type="bibr" rid="B6">2018</xref>). In the polar context, the discussion around this potential for behavior change revolves around the &#x0201C;ambassadorship&#x0201D; concept, which has been questioned about its accuracy and effectiveness in this context. Ambassadorship is widely utilized in the promotion, messaging, and educational experiences of Antarctic tourism to describe representatives who enact behavior that protect or sustains the place (IAATO, <xref ref-type="bibr" rid="B27">2023a</xref>). Lindblad linked the term of ambassadorship to the positive benefits of experiencing an educational expedition in the Antarctic in the 1960s, and when IAATO formed in 1991, they continued to promote the program (Manley et al., <xref ref-type="bibr" rid="B36">2017</xref>; IAATO, <xref ref-type="bibr" rid="B24">2020a</xref>). The concept and specific term usage focusing on tourists are clearly present within the Antarctic industry and research narratives, which might result from a lack of resident Antarctic population who could serve as ambassadors. In contrast, official Arctic Ambassadors exist in most Arctic countries who are political appointees with defined responsibilities for the area, and who may or may not come from the local population (Solli et al., <xref ref-type="bibr" rid="B49">2013</xref>). As the Arctic region shares similar challenges with tourism, it is less clear whether or how this concept or term has permeated geographical boundaries to be used by researchers to examine tourist behavior change in other polar environments. This paper seeks to first identify and define common terminology related to the ambassadorship concept, and then present results from a scoping review to explore the identified terms&#x00027; usage, boundaries, implications, and differences within the scope of polar tourism research. This work is intended to serve as the initial step toward more in-depth examination of these terms with respect to their conceptual commonalities and differences.</p>
<sec>
<title>1.1 Defining the terms</title>
<p>Ambassadorship, advocacy, and stewardship seem to be commonly used terms across polar tourism research to describe responsibilities expected of someone who aims to protect something or some place. The term advocacy or advocation derives its meaning from the French, &#x0201C;<italic>advocacie,&#x0201D;</italic> meaning &#x0201C;(legal) pleading,&#x0201D; now an &#x0201C;action of pleading for or support for&#x0201D; (Merriam-Webster, <xref ref-type="bibr" rid="B39">2022a</xref>; Oxford English Dictionary Online, <xref ref-type="bibr" rid="B42">2023a</xref>). The original definition of steward, derived from Old English &#x0201C;s<italic>tiweard</italic>,&#x0201D; defines the job duties of one managing a household or estate (Oxford English Dictionary Online, <xref ref-type="bibr" rid="B44">2023c</xref>); however, the word has evolved and can also broadly mean &#x0201C;the careful and responsible management of something entrusted to one&#x00027;s care (i.e., of natural resources) (Pe&#x000E7;anha Enqvist et al., <xref ref-type="bibr" rid="B46">2018</xref>; Merriam-Webster, <xref ref-type="bibr" rid="B40">2022b</xref>). The word &#x02018;ambassador&#x00027; was first used in the fourteenth century, derived from Medieval Latin &#x0201C;<italic>ambasciator,&#x0201D;</italic> for &#x0201C;to communicate&#x0201D; and late Latin &#x0201C;<italic>ambascia&#x0201D;</italic> meaning &#x0201C;mission, task, journey&#x0201D; (Merriam-Webster, <xref ref-type="bibr" rid="B38">2021</xref>). Through etymological variations from Latin to modern English, the word has largely kept its meaning as &#x0201C;an envoy,&#x0201D; usually describing diplomats or appointed persons serving as &#x0201C;resident representatives&#x0201D; (Oxford English Dictionary Online, <xref ref-type="bibr" rid="B43">2023b</xref>).</p>
<p>Ambassadorship has been defined by the industry. As per IAATO, ambassadors are people who, &#x0201C;love and respect the region, educate others by sharing their experiences, advocate for Antarctica, and protect the region by making positive changes at home&#x0201D; (IAATO, <xref ref-type="bibr" rid="B24">2020a</xref>). By this definition, Antarctic Ambassadors are supposed to serve as representatives of a place (Antarctica) by having some connection to and local knowledge of that place, and they must practice advocacy for and stewardship of, or on behalf of that place. The broad definition of the term gave way to many iterations used to create organization-specific programs and designations (Braun et al., <xref ref-type="bibr" rid="B8">2013</xref>; Uchinaka et al., <xref ref-type="bibr" rid="B57">2019</xref>). For example, ambassadors have also been categorized as: destination ambassadors, volunteer ambassadors, citizen brand ambassadors, place ambassadors, tourism ambassadors, and STEM (Science, Technology, Engineering, and Mathematics) ambassadors (Chancellor et al., <xref ref-type="bibr" rid="B11">2021</xref>). Place ambassadorship may be the most closely related to polar ambassadorship as the assumption here is that polar travelers who enjoy and are inspired by their trip would promote their destination once home. The application of ambassadorship to Antarctica, however, seems inconsistent with the traditionally defined place ambassadorship as Antarctica does not have a local population from which ambassadors emerge to represent their place and the resources on which they depend (De Nisco et al., <xref ref-type="bibr" rid="B14">2017</xref>; Chancellor et al., <xref ref-type="bibr" rid="B11">2021</xref>). Alexander et al. (<xref ref-type="bibr" rid="B4">2019</xref>) offers a definition of Antarctic Ambassadors based on a Delphi study with more specific parameters, &#x0201C;An Antarctic ambassador is someone (i.e., individual or group) who has a connection to, knowledge of and passion for the Antarctic (as a space, place or idea), who represents and champions Antarctica and its values, and who supports Antarctica through communication and behavior&#x0201D; (p. 502). In the Arctic, Stewart and Draper (<xref ref-type="bibr" rid="B51">2006</xref>) and Wilson (<xref ref-type="bibr" rid="B62">2019</xref>) explored the ambassadorship concept through the lens of cruise tourism and last chance tourism, respectively. While they found similar applicability of this concept as for Antarctica, they noted the consequence of using the term for tourism marketing which could result in more visitation and resultant environmental impacts.</p>
<p>The above few studies explored the connection of the ambassadorship concept with the polar regions, but what does it truly mean to be an ambassador? A better understanding of this and related terminology as currently used can stimulate research on these concepts and the measurements of them. It could also have implications for tour operators in understanding whether they are achieving their educational or experiential goals. More broadly, this review helps inform the discourse of polar tourism by providing a concise summary of how the terminology is applied in the research literature.</p></sec></sec>
<sec id="s2">
<title>2 Methods</title>
<p>We conducted a scoping review for its usefulness in identifying the boundaries of a topic in the peer-reviewed literature, using inclusion and exclusion criteria and matrices to organize and present results (Par&#x000E9; and Kitsiou, <xref ref-type="bibr" rid="B45">2017</xref>; Xiao and Watson, <xref ref-type="bibr" rid="B63">2019</xref>, p. 99). The search was conducted using Web of Science, EBSCOhost, Google Scholar, and ERIC databases, which included references published in English. We chose to examine the language in scientific literature, rather than tourism marketing materials, as we are interested in how such language is defined and utilized in the published academic work. Researchers studying polar tourism not only provide insights into the programs and language used by the industry, but also empirical analyses. Due to the similarity of <italic>advocacy</italic> and <italic>stewardship</italic> to <italic>ambassadorship</italic> in associating with pro-environmental behavioral outcomes of tourists (Maher et al., <xref ref-type="bibr" rid="B35">2001</xref>; Bennett et al., <xref ref-type="bibr" rid="B7">2018</xref>), these three terms were all included in the searches for articles that discuss tourists&#x00027; outcomes. Specifically, we identified articles based on the following search criteria:</p>
<list list-type="bullet">
<list-item><p>Keyword terms included: Antarctic<sup>&#x0002A;</sup>, ambassador<sup>&#x0002A;</sup>, ambassadorship<sup>&#x0002A;</sup>, touris<sup>&#x0002A;</sup>, arctic, arctic tourism, stewar<sup>&#x0002A;</sup>, polar, advoca<sup>&#x0002A;</sup>. A precursory search including all of the possible keywords provided articles about tourism in those regions but not about tourism outcomes. To limit irrelevant search results, fewer keywords were included and were swapped out to see which terminology produced different results (see <xref ref-type="fig" rid="F1">Figure 1</xref>).</p>
</list-item>
<list-item><p>Articles that focused on tourism in a polar region: Antarctica, the Arctic region (high, low, and sub-Arctic were included), specifically: Kaktovik, Alaska; Churchill and Nunavut, Canada; western Greenland: and Iceland. Climate-threatened, &#x0201C;last chance&#x0201D; tourism destination term included, which produced 2 articles that included both Arctic and non-Arctic study areas. These were included due to the Arctic study area and the meeting of other criteria.</p></list-item>
<list-item><p>Articles that mentioned ambassador(ship), steward(ship), or advocate(cy) or pro-environmental behavior.</p></list-item>
<list-item><p>Articles must focus on polar tourism including: tourism impacts, tourist outcomes, tourist motivations.</p></list-item>
</list>
<fig id="F1" position="float">
<label>Figure 1</label>
<caption><p>Search results showing key terms, region, and methodology for all 16 articles, organized by region and by year of publication (reverse chronological order).</p></caption>
<graphic mimetype="image" mime-subtype="tiff" xlink:href="frsut-02-1263644-g0001.tif"/>
</fig>
<p>A combination of the above keywords was entered to find relevant articles. The search was conducted for all time periods. Results were screened for relevance to the research topic based on the stated criteria. A matrix was utilized to extract important data from each article, including authors, research questions, methodology, findings, terminology, and geographic location (Goldman and Schmalz, <xref ref-type="bibr" rid="B17">2004</xref>). The matrix allowed for a simple analysis of similarities and differences between the studies.</p></sec>
<sec id="s3">
<title>3 Results and discussion</title>
<p>After screening for results that fit into our selection criteria, the search produced only 16 articles (<xref ref-type="fig" rid="F1">Figure 1</xref>). Selected articles were all published from 2001 through 2022. Antarctica was the most prevalent study destination (<italic>n</italic> = 8). Arctic study areas were more diverse given that the region can be categorized into high, low, or sub-Arctic regions (United Nations Environment Programme, <xref ref-type="bibr" rid="B58">2013</xref>). Some (<italic>n</italic> = 2) focused on the Arctic region in general, the majority were conducted in sub to low Arctic destinations (<italic>n</italic> = 4), and one in the high Arctic. One study focused on both poles. The main research methods were surveys (<italic>n</italic> = 10) and literature reviews (<italic>n</italic> = 5), with one study that conducted a Netnography (method for studying online cultures). Surveys included knowledge tests, connection to nature scales, and questions about attitudes, environmental behaviors, and future behavior intentions. Keyword search for articles revealed the overlapping nature of terms, where four articles were found using both ambassador and steward, and one article was found with all three. Although advocacy as a keyword produced only one relevant, repeated result, the term was used in five of the articles, although only in reference to action from ambassadors. Ambassador and steward appeared in studies conducted in both Arctic and Antarctic, and <xref ref-type="fig" rid="F1">Figure 1</xref> below shows the presence of the terms across region.</p>
<p>There were two distinct study designs in which the researchers explored the concepts: (1) research that was related to understanding either tourist motivations, perceptions, knowledge and/or behavior, with the intention that measuring some combination of those could transfer to management action to promote ambassadorship, stewardship, or advocacy, and (2) research in which the author(s) developed conceptual pieces (Delphi study, literature reviews, research notes) to analyze the meaning and implications of term concepts on tourism, or tourism directly.</p>
<sec>
<title>3.1 Type 1 study design: understanding tourists through the use of terms</title>
<p>The majority of articles (<italic>n</italic> = 10), including: Powell et al. (<xref ref-type="bibr" rid="B47">2008</xref>), Eijgelaar et al. (<xref ref-type="bibr" rid="B15">2010</xref>), Groulx et al. (<xref ref-type="bibr" rid="B19">2016</xref>, <xref ref-type="bibr" rid="B18">2019</xref>), Manley et al. (<xref ref-type="bibr" rid="B36">2017</xref>), Vila et al. (<xref ref-type="bibr" rid="B61">2016</xref>), Miller et al. (<xref ref-type="bibr" rid="B41">2020</xref>), Hehir et al. (<xref ref-type="bibr" rid="B22">2021</xref>), Abrahams et al. (<xref ref-type="bibr" rid="B2">2022</xref>), and Cajiao et al. (<xref ref-type="bibr" rid="B10">2022</xref>) can be categorized into the first study design. Ambassadorship was the favored term for studies conducted in Antarctica (<italic>n</italic> = 5) with one study that analyzed data from both poles and used only ambassadorship (Hehir et al., <xref ref-type="bibr" rid="B22">2021</xref>), and one used both (Cajiao et al., <xref ref-type="bibr" rid="B10">2022</xref>). Terminology within Arctic studies remains more split between stewardship (<italic>n</italic> = 3) and ambassadorship (<italic>n</italic> = 1), and one (Miller et al., <xref ref-type="bibr" rid="B41">2020</xref>) used both. Researchers set out to understand the experiences of visitors, including their motivations for engaging in polar tourism, perceptions, knowledge, and other factors (e.g., type of tour, length, educational offerings, location, demographics), and how these factors impact the development of ambassadorship, commonly measured as pro-environmental attitudes or pro-environmental behaviors (PEB). PEB was measured by pre/post general and Antarctica-specific environmental concerns, management preferences, and public/private sphere behavioral intentions; for example, concern about overfishing, and support for tourism regulations (p. 5). Manley et al. (<xref ref-type="bibr" rid="B36">2017</xref>) found alignment between the motivation to learn on an expedition cruise and an increase in post-trip, Arctic-specific knowledge and self-reported public sphere (donating, voting), pro-environmental behaviors (Manley et al., <xref ref-type="bibr" rid="B36">2017</xref>). Powell et al. (<xref ref-type="bibr" rid="B47">2008</xref>) found similar motivations and positive increases in Antarctic-specific knowledge 3 months after a trip, but &#x0201C;general environmental behavior intentions,&#x0201D; remained stable after increasing immediately after the trip (p. 236). As also reflected in Miller et al. (<xref ref-type="bibr" rid="B41">2020</xref>), the relationship between visitor motivations and their actual experiences, especially emotional experiences on a tour, can be predictors of PEB. Groulx et al. (<xref ref-type="bibr" rid="B19">2016</xref>, <xref ref-type="bibr" rid="B18">2019</xref>) found further evidence that the emotional component of experience, specifically nature connection and place identity in these cases, can mediate the decision to engage in carbon offsetting. Evidence from Hehir et al. (<xref ref-type="bibr" rid="B22">2021</xref>) may further point to a relationship between emotional connection and ambassadorship. As longitudinal data from an Arctic and Antarctic &#x0201C;Students on Ice&#x0201D; program found, social identity, which is mediated by a strong human-nature relationship (Inclusion of Nature in Self) can influence pro-environmental behavior (p. 1647). More recently, Cajiao et al. (<xref ref-type="bibr" rid="B10">2022</xref>) found that different motivation types of Antarctic tourists and trip characteristics were associated with different strengths of PEB intentions, which could be mediated by experiential outputs such as learning and satisfaction.</p>
<p>While the majority of authors did collect data on both motivations and behavioral outcomes, some focused more on measuring the existence of ambassadorship through behavior. General environmental behavior measured in many surveys typically encompassed public and private sphere behaviors, ranging from &#x0201C;joining environmental organizations, donating money, voting, and supporting location-specific, management and conservation action, to avoiding environmentally harmful products,&#x0201D; (Stern, <xref ref-type="bibr" rid="B50">2000</xref>; Powell et al., <xref ref-type="bibr" rid="B47">2008</xref>, p. 236; Manley et al., <xref ref-type="bibr" rid="B36">2017</xref>). There seemed to be a connection between how much the researchers explored the concept of ambassadorship and how extensive their PEB measures were. Abrahams et al. (<xref ref-type="bibr" rid="B2">2022</xref>) conducted a Nethnography of TripAdvisor reviews for evidence of a &#x0201C;last chance tourism&#x0201D; motivation and post-trip perceptions of the glacier destinations. They concluded that motivations were much more varied than only LCT, and that visitor reviews did not reflect an increase in ambassadorship attitudes or behaviors, by nature of visitors still encouraging more travel to the glaciers. Similarly, Eijgelaar et al. (<xref ref-type="bibr" rid="B15">2010</xref>) directly measured a very specific facet of ambassadorship behavior, which they defined in this study as reducing or offsetting travel emissions, future travel intentions, and climate change awareness. In the case of Miller et al. (<xref ref-type="bibr" rid="B41">2020</xref>), the authors dedicated a large portion of the discussion to defining the concept of ambassadorship, settling on the definition of &#x0201C;a representative or promoter&#x0201D; (p. 1704). They collected survey responses on a variety of conservation behaviors that required &#x0201C;passion, care, and knowledge&#x0201D; of the Arctic environment (Miller et al., <xref ref-type="bibr" rid="B41">2020</xref>). These behaviors ranged from social media information sharing to advocating for specific laws and policies (p. 1715). Contrarily, Vila et al. (<xref ref-type="bibr" rid="B61">2016</xref>) conducted in-depth interviews and <italic>in situ</italic> surveys and found &#x0201C;little spontaneous confidence in the ambassadorship effect,&#x0201D; in relation to the creation of ecological orientations (p. 455). The authors seem to recognize the connection between place, education, and subsequent conservation behaviors; however, there is very little discussion about whether those behaviors are all that goes into ambassadorship, stewardship, or advocacy, or whether these concepts mean more than specific behaviors in these contexts.</p>
<p>This category seems to make clear the ubiquity of an ambassadorship concept across the polar regions, as these studies sought to understand the factors influencing polar tourisms&#x00027; efficacy in facilitating &#x0201C;ambassadorship,&#x0201D; &#x0201C;stewardship,&#x0201D; or &#x0201C;advocacy&#x0201D; behavior. Despite the interchangeability of stewardship with ambassadorship, specifically in the Arctic, the narrative in each of these studies reinforces that it is worth understanding visitor experiences because of the stated potential for positive change in environmental behavior. The approach to understanding an &#x0201C;ambassadorship&#x0201D; effect varies (<xref ref-type="fig" rid="F2">Figure 2</xref>), but the end goal is the same. Motivations, behavior, and the related components that are commonly measured, function as contributing factors (i.e., perceptions, knowledge, trip characteristics) (Powell et al., <xref ref-type="bibr" rid="B47">2008</xref>; Miller et al., <xref ref-type="bibr" rid="B41">2020</xref>), allowing researchers to see gaps in the real-world ambassadorship effect, and to suggest solutions to operators on how to create programming that will promote ambassadorship behavior (Manley et al., <xref ref-type="bibr" rid="B36">2017</xref>; Miller et al., <xref ref-type="bibr" rid="B41">2020</xref>).</p>

<title>3.2 Type 2 study design: ethical and conceptual explorations of the terms</title>
<p>The second type of study design was more conceptual in nature, facilitating ethical discussions and dissecting meaning from terms. Out of these six studies: Maher et al. (<xref ref-type="bibr" rid="B35">2001</xref>), Verbitsky (<xref ref-type="bibr" rid="B60">2013</xref>), Tin (<xref ref-type="bibr" rid="B56">2017</xref>), Alexander et al. (<xref ref-type="bibr" rid="B4">2019</xref>), Taylor et al. (<xref ref-type="bibr" rid="B53">2020</xref>), and Kerber (<xref ref-type="bibr" rid="B30">2022</xref>), four focused on Antarctica and two on the Arctic. Interestingly, four studies utilized both ambassadorship and stewardship interchangeably, one article only used ambassador and one the same with steward, both in Antarctica. Although the majority of these conceptual papers were focused on Antarctica, topics held true across the polar regions. Three main themes emerged from this group of publications: the meaning of stewardship in relation to regulating tourism, how narratives surrounding tourism could be used to promote ambassadorship and defining ambassadorship itself. There was general recognition that in both regions, the changing climate has opened up new potential for tourism, and this should prompt more regulation, action, or consideration. As reduced sea ice in the Arctic has already increased tourist mobility in the Northwest Passage, Kerber (<xref ref-type="bibr" rid="B30">2022</xref>) leads a fascinating discussion around the ethical and social justice ramifications of tourism in that region. In short, companies marketing Arctic cruises rely on out-of-touch narratives about pristine and unexplored landscapes that ignore the realities of changing a climate and the impact on Arctic Native populations. Kerber (<xref ref-type="bibr" rid="B30">2022</xref>) advocates that visitors may be more positively influenced to become ambassadors if they were exposed to more realistic narratives. This idea is echoed by Taylor et al. (<xref ref-type="bibr" rid="B53">2020</xref>) who explores how incorporating citizen science into polar cruises may increase visitor awareness of interconnected systems and inspire ambassadorship attitudes or behaviors.</p>
<p>Another key discussion present in multiple articles centered around what is meant by stewardship. In Antarctica specifically, stewardship is often used in relation to the responsibilities of the Antarctic Treaty System and Consultative Parties when it comes to tourism. Tin (<xref ref-type="bibr" rid="B56">2017</xref>) pushes for the incorporation of environmental ethics in how we determine the use and management of Antarctica based on its intrinsic value as an intact wilderness ecosystem rather than by its economic opportunity. Within this discussion, Tin (<xref ref-type="bibr" rid="B56">2017</xref>) notes that the ATCPs have accepted a stewards&#x00027; responsibility to preserve Antarctica for the &#x0201C;interest of all mankind&#x0201D; and future generations (p. 62). Maher et al. (<xref ref-type="bibr" rid="B35">2001</xref>) and Verbitsky (<xref ref-type="bibr" rid="B60">2013</xref>) echo the sentiment that tourism is a significant activity in Antarctica that the ATCPs are responsible for as stewards of the continent.</p>
<p>Despite the pervasiveness of the ambassadorship idea, very few studies explore the conceptual meaning of the term. Maher et al. (<xref ref-type="bibr" rid="B35">2001</xref>) examines existing literature up until the early 2000s and notes the interchangeability with stewardship and advocacy already present across regions. Additionally, authors suggest research objectives that analyze the whole visitor experience to understand the cyclical nature of ambassadorship, reflecting the first type of articles examined in this review. Alexander et al. (<xref ref-type="bibr" rid="B4">2019</xref>) offers a more in-depth and empirical look at the concept through a Delphi study with Antarctic experts. Experts define conceptual boundaries of ambassadorship, explaining that ambassadors should hold a significant amount of &#x0201C;passion, care and knowledge&#x0201D; in order to &#x0201C;defend and advance Antarctic values, raise awareness of Antarctic issues and promote an understanding of Antarctica as a place and a culture&#x0201D; (p. 502). While other articles assume truth in the concept and precision in its description, Alexander et al. (<xref ref-type="bibr" rid="B4">2019</xref>) challenges the status quo and explores what it means to truly be an ambassador.</p></sec></sec>
<sec id="s4">
<title>4 Implications and conclusions</title>
<p>This review synthesized the usage, boundaries, implications, and differences of terminology related to ambassadorship within polar tourism research. Despite the formal and colloquial association of ambassadorship with Antarctic tourism, researchers have applied the concept to analyze potential pro-environmental behavior outcomes in the Arctic as well. Within the Arctic, and occasionally in the Antarctic, stewardship is used interchangeably to explain the same concept. Unlike IAATO in the Antarctic, the Arctic tourism industry does not put forth cohesive language about creating ambassadors, stewards, or advocates from their tourism experiences. However, with the prevalence of the idea that polar experiences can influence tourists&#x00027; pro-environmental behaviors, application of the ambassadorship concept to Arctic tourists both by professionals and researchers may be beneficial in creating a more complete picture of polar tourism. Tour operators that wish to keep utilizing this term should clearly define expectations, and researchers should keep pushing to understand the outcomes associated with this type of tourism and to better define the use of the terms. As the term Arctic Ambassadors is already established for official representatives from Arctic countries, extending it to tourists in the Arctic should be done judiciously so it does not create confusion with the official Arctic Ambassadors.</p>
<p>Experiences in polar regions are primarily educational through nature encounters, and many factors influence how tourists perceive their experience and whether that contributes to attitude or behavior change around conservation. An established connection to nature and a desire to learn about natural environments or the effects of climate change can motivate visitation (Groulx et al., <xref ref-type="bibr" rid="B19">2016</xref>). Visiting polar regions provide tourists with an opportunity to witness the effects of climate change first-hand; however, evidence also shows that without proper on-site interpretation, visitors can misinterpret the information in front of them (Miller et al., <xref ref-type="bibr" rid="B41">2020</xref>). This point is echoed by van Soest (<xref ref-type="bibr" rid="B59">2023</xref>)&#x00027;s recent critique of the value of Arctic Expedition despite the use of &#x0201C;science ambassadors&#x0201D; for its tourist participants. Limited longitudinal research suggests that visitors can retain practical knowledge at least 3 months after a journey, and certain factors, such as occurrence of epiphanies, length of experience, and total minutes educated, can increase the likelihood of engagement in pro-environmental behaviors (Powell et al., <xref ref-type="bibr" rid="B47">2008</xref>; Miller et al., <xref ref-type="bibr" rid="B41">2020</xref>). Additional research on the different factors involved in polar tourist experiences and which factors are most influential in facilitating that connection could help operators create more effective programming to facilitate pro-environmental outcomes. The effectiveness of providing specific actions or behavior tourists could engage in to contribute to conservation produced mixed results depending on other factors influencing tourists&#x00027; attitudes, beliefs, and experiences. Contributing to concept exploration may need to involve questions that Alexander et al. (<xref ref-type="bibr" rid="B4">2019</xref>) posed, &#x0201C;what then might such behavior look like? Is it conservation behaviors in a person&#x00027;s daily life such as supporting an environmental organization, reducing waste, walking to work, or is it enough to share photos of a trip on Facebook and tell your friends?&#x0201D; (p. 503).</p>
<p>We recommend researchers continue to advance the understanding, conceptualization, and operationalization of these terms, as well as to extend the scope of examination to include non-English scientific literature, such as Norwegian and Russian references in which these terms also appeared. Our methods may have led to search results that focused on the environmental aspects of ambassadorship, even in the Arctic. Changes in keywords and selection criteria may be needed if the social and community aspects of ambassadorship are of interest in future studies. Future research is also encouraged to apply citation impact analysis to examine how the terms and concepts introduced by seminal publications (e.g., Eijgelaar et al., <xref ref-type="bibr" rid="B15">2010</xref>) evolve in, and impact on, the scientific literature across disciplinary boundaries.</p>
<p>Ambassadorship, stewardship, and advocacy can be all sides of the same coin, subject to similar research seeking to prove their validity and efficacy within polar tourism. An understanding of the state of knowledge and academic discourse of these terms should inform the industry on how consistent or deviant it is in using these terms in its marketing and education programs, prompting debates about the implications and potential consequences if significant discrepancies exist. Despite the main focus of these studies being on measuring tourist outcomes, Tin (<xref ref-type="bibr" rid="B56">2017</xref>) starts to expand that boundary by labeling the Antarctic Treaty Consultative Parties as stewards themselves. While tourists are an important population to foster ambassadorship, this inclusion of the ATCPs prompts questions about who else in the polar tourism industry could function as ambassadors. Further research on developing and expanding the ambassadorship concept may open up the field to new perspectives on who could be considered an ambassador, which may help validate the accuracy of the concept in these contexts.</p></sec>
