The value of interdisciplinarity for solving complex coastal problems is widely recognized. Many early career researchers (ECRs) therefore actively seek this type of collaboration through choice or necessity, for professional development or project funding. However, establishing and conducting interdisciplinary research collaborations as an ECR has many challenges. Here, we identify these challenges through the lens of ECRs working in different disciplines on a common ecosystem, the Norwegian Skagerrak coast. The most densely populated coastline in Norway, the Skagerrak coast, is experiencing a multitude of anthropogenic stressors including fishing, aquaculture, eutrophication, climate change, land runoff, development, and invasive species. The Skagerrak coastline has also been the focus of environmental science research for decades, much of which aims to inform management of these stressors. The region provides a fantastic opportunity for interdisciplinary collaboration, both within and beyond the environmental sciences. This perspective article identifies the barriers ECRs in Norway face in establishing interdisciplinary and collaborative research to inform management of coastal ecosystems, along with their root causes. We believe our discussion will be of broad interest to all research institutions who employ or educate ECRs (in Norway and worldwide), and to those who develop funding mechanisms for ECRs and interdisciplinary research.

 early career researchers interdisciplinarity marine science and technology Norway ocean Skagerrak Introduction

In a time when global anthropogenic impacts on ecosystems call for urgent solutions, interdisciplinary collaboration can push the boundaries of marine research to enable innovative knowledge building and provide resource managers and policymakers with tools to secure a productive and healthy ocean (Ledford, 2015). As such, more than ever before, researchers are expected to think and work across disciplines to solve pressing challenges (Ledford, 2015; Rylance, 2015; Andrews et al., 2020). Across the globe, interdisciplinary institutes and think tanks push innovation by facilitating knowledge exchange (Ledford, 2015; Vienni Baptista et al., 2019; Mäkinen et al., 2020). The European Union framework program Horizon 2020 has heavily promoted interdisciplinary research, even so far as stating that it is the “key to future scientific breakthroughs,” and awarded grants accordingly (Science Europe, 2012).

Early Career Researchers (ECRs) have an essential role within academic research, as driving forces that push science forward with research-focused workloads, fresh ideas, and enthusiasm (Friesenhahn and Beaudry, 2014; Andrews et al., 2020). Despite the documented benefits of interdisciplinarity, ECRs face many barriers to working successfully across disciplines (Table 1). The structure of academia is one such barrier, with field-specific funding calls, discipline-specific jargon, and short-term contracts, making interdisciplinary collaborations particularly challenging for ECRs (Brewer, 1999; Bromham et al., 2016; Andrews et al., 2020). This perspective article provides an overview of the barriers faced by ECRs within a recently established interdisciplinary research center in southern Norway, and their causes. To our knowledge, it is the first of its kind to focus on interdisciplinary coastal research in Norway and adds to the limited information on the topic in Scandinavia (Table 1 and see also Supplementary Material: Literature search).

Summarized barriers to successful interdisciplinary research from an early career perspective and suggested solutions, from literature published since 2015.

With Norway being a maritime nation, the Norwegian government’s long-term plan for research and higher education has a particular focus on research-based innovation and industry-oriented research, with the ocean being one of the priority areas (Norwegian Ministry of Education and Research, 2019). Investment in technology and research infrastructure is highlighted as crucial to promoting sustainable development and to increasing the value of industries in ocean and coastal areas. Norway’s continued investment in this sector is reflected by the country having the world’s highest proportion of marine scientists per capita (UNESCO-IOC, 2020). Norway could be used as an example by other countries of how to begin removing barriers for ECRs.

The aim of this article is to (1) identify barriers to interdisciplinary research faced by ECRs who work on a common ecosystem in Norway and (2) consider the root causes of these barriers. By sharing our perspective, we hope to draw attention to practices that need to be reviewed for more effective interdisciplinary research by ECRs in Norway and worldwide, leading to better informed management of coastal ecosystems during this time of global change. A background description of the Norwegian Centre for Coastal Research and the development of this manuscript can be found in the Supplementary Material (Supplementary Material: Background of This Study).

 Common Barriers to ECR Interdisciplinarity

To identify barriers to their research and their causes, the authors participated in individual and small-group work during winter and spring 2019/2020, then discussed these during a 3 days virtual workshop held in April 2020 (for details, see Supplementary Material: Background of this study). Three major themes emerged with regard to barriers, related to (1) short-term employment, (2) knowledge sharing via networks and partnerships, and (3) data-associated limitations (Figure 1). Within these themes, barriers were related to three main types of causes: (A) practical limitations hindering ECR research, (B) structural limitations inherent to the local research environment, and (C) systemic limitations inherent to the current scientific, political, and societal situation in which research occurs (later referred to as “practical,” “structural,” and “systemic” causes, Figure 1).

Practical, structural, and systemic causes contributed to barriers to interdisciplinary research across the three overarching themes (bold text) and the specific examples (regular text) identified by ECRs in marine science.

This perspective is in agreement with previous work reporting that main barriers limiting ECRs’ capacity for interdisciplinary research are not only of scientific origin but rather due to the working environment and conditions (Andrews et al., 2020; Brasier et al., 2020). A review of recent literature summarized in Table 1 suggests many diverse barriers to successful interdisciplinary collaborations for early career researchers. Since most of the barriers and their causes were raised by several researchers independently, we determined that these challenges occur across subdisciplines and will continue to hinder the progress of future ECRs unless they are addressed directly. As such, we outline below the identified barriers and causes. We acknowledge that our perspectives are biased toward our experiences in natural sciences and of being an ECR in Norway. Norway has comparatively favorable working conditions, specifically in relation to salary and gender equality at the ECR stage in our general field than many other countries. Furthermore, in Norway flatter structures are more common than in many other countries, which enables ECRs to engage with senior researchers and management staff more easily, as well as provide constructive criticism in regard to the work environment with less fear of repercussions. We discussed solutions, but given that we do not know the practicalities or secondary consequences of these, we have not made specific recommendations. Instead, we include our suggestions as a starting point for further discussion both briefly within the text and in more detail in Supplementary Material (Supplementary Material: Potential Solutions to Causes and Prevention of Barriers). In addition, solutions to the barriers identified in literature have been added to Table 1.

Barrier 1: Temporary and Short-Term Contracts

An overarching topic of our discussions related to temporary contracts and time limitations of short-term employment, which are not conducive to interdisciplinarity when considering the time investment needed to explore and establish collaborative research. There were several challenges associated with this barrier, such as pressure to publish; balancing time required to learn about the research environment, acquire skills, and conduct research; and job insecurity. The high competition for limited postdoc and permanent positions may not foster a collaborative working environment, as ECRs may feel they are in competition with their colleagues for limited resources. Time is a limiting factor for ECRs where, as a consequence, mental health and well-being suffer (Gewin, 2012; Woolston, 2018; Bosanquet et al., 2020; Table 1) with clinical symptoms such as depression and anxiety up to six times higher in graduate students compared to the general population (Evans et al., 2018). The problematic nature of short-term contracts for ECRs has become especially visible during the ongoing pandemic (Pardo et al., 2020). However, these problems were also identified by ECRs prior to COVID-19 and will not disappear post COVID-19 if long-term solutions are not created on all levels (Figure 1 and Supplementary Table 1). Furthermore, there is a growing body of literature related to career uncertainty in general and the associated economic and personal costs (Garwood, 2014; Bozzon et al., 2017; Chesters et al., 2019; Table 1). Underlying practical, structural, and systemic causes were identified, as detailed below.

Practical Causes

Practical reasons that short-term contracts are a barrier to ECRs establishing successful interdisciplinary projects include lengthy processes, such as finding potential collaborators and developing project plans that suit all partners; designing and trialing new experimental methods, which often have unpredictable results and timeframes; and seasonal limitations on field sampling or laboratory experiments.

 Structural Causes

Time limitations due to fixed-term contracts may also become a barrier for several practical reasons. Many tasks ECRs have to complete during their short-term employment may be mandatory or prescribed by their local research environment (i.e., following of internal routines and procedures). As specific examples, such time-demanding tasks may be (1) mandatory legislative approval for data collection or animal welfare approval for practical work, mandatory safety, lab, and method training. Although recognized as highly important, these tasks may be overly time consuming if proper guidance is not provided immediately. (2) ECRs depend on cyclical and highly competitive funding opportunities to cover field and lab expenses—funding opportunities which may have months between initial application, decision, and receipt of grant money. (3) Furthermore, interdisciplinarity requires working outside of an ECR zone-of-knowledge, whereby completing tasks and learning new methods may require additional time (Andrews et al., 2020). Lastly, (4) while learning native language is not a requirement for international staff on temporary contracts in most institutions in Norway, much of the communication between colleagues is conducted in the native speech. Such informal discussions are generally a great source for learning about colleagues’ work and opportunities to collaborate. Language courses are often only provided to permanent staff and, where available to temporary employees, are often at extra costs (time and money). Free language classes may sometimes be available at affiliated universities; however, those may not be frequent enough to provide the practice required to adequately engage in conversation until the end of the temporary contracts and are often not at the appropriate level to enable work-related conversation (Mentzoni et al., 2016).

 Systemic Causes

ECRs are typically expected to move during their academic career in order to expand their research and network horizon, i.e., take temporary positions (Bridle et al., 2013; Brasier et al., 2020; Fork et al., 2020). This funding and employment system appears to be driven by several assumptions, in particular the ECRs’ ability to relocate, i.e., the traditional view of ECRs as young, able, single, or with a stay-at-home spouse who is willing and able to relocate, and not as parents or carers for vulnerable relatives, or unable to relocate for other reasons (Jaeger-Erben et al., 2018; Andrews et al., 2020; Brasier et al., 2020). However, this assumption is exclusionary to the majority of our ECR authors who do not fit that demographic. There may also be an assumption that forced relocation to a new research environment, e.g., as a postdoctoral researcher in another country, is more valuable than long-term employment within one location. Yet, shorter research visits and exchanges with partner sites, instead of contractual relocation, can be an efficient option for knowledge transfer in both directions and on various levels (on a national, institutional, and individual level). In addition, while new knowledge and new studies could be conducted at the partner site, ongoing research and networks at the already established “home institute” could be maintained and continued, making investment in interdisciplinary partnerships more likely.

 Barrier 2: Networks and Partnerships (Knowledge Sharing Across Institutions)

Sharing of methods, data, and knowledge among disciplines is essential to pushing scientific frontiers forward. Barriers to interdisciplinarity identified by ECRs included access to appropriate networks, establishing successful collaborations, and overcoming communication barriers between disciplines (Supplementary Table 2 and Table 1). ECRs may largely depend on input from collaborators, supervisors, and senior academics, which may not fully acknowledge the needs of the ECRs or provide the required guidance. The problem is asymmetric, as for ECRs future employment may depend on successful interdisciplinary research experience while the project may not be pivotal for the careers of the senior researchers involved. Reluctance in sharing methods, data, and knowledge between individuals, research groups, disciplines, or even research generations was found to be a barrier to successful collaborations for ECRs.

Practical Causes

We identified several practical causes, such as the lack of holistic perspectives in the planning of data collection and experimentation, the difficulties in communication and open data sharing between disciplines and new partner institutions, the traditional divisions among sciences and the different types of knowledge produced, and lack of resources or technical limitations.

 Structural Causes

Engagement with stakeholders, practitioners, and local authorities, as well as the broader society is a prerequisite for turning research into action and to overcoming real-time coastal challenges in a long-lasting way. However, a lack of such established networks within research centers may prevent ECRs from connecting with relevant contacts and implementing their research. Interdisciplinary research institutes may be able to help ECRs overcome those structural barriers by actively promoting encounters between ECRs and already established networks (Bridle et al., 2013; MacLeod, 2018).

 Systemic Causes

Time and funding may be too limited to contact, exchange, and develop novel methods in collaboration with partners during an ECR contract. Although the general attitude toward sharing has largely improved over the past decade, sharing methods across disciplines and with new contacts can still be challenging. Often, collaborators may not be willing to share, contribute, or exchange expertise with new members, as ECRs will be less “known” compared to more senior researchers within collaborator networks and so may be less trusted with data. As a result, ECRs may not have access to new methods before they are published. Publication of novel, interdisciplinary methods may be more time demanding than traditional methods as reviewers or editors may be more skeptical or perceive themselves as less qualified to review the manuscript.

 Barrier 3: Data-Related Barriers

Reliable data is an integral part of research and remains so for interdisciplinary collaboration. Data acquisition, cleaning, normalization, and integration across interdisciplinary areas are an inherent part of ECR work. Technical advancements can provide significant assistance by simplifying the data acquisition process. The barriers we identify affect ECRs’ research in terms of quality, quantity, and efficiency (Table 1). Resolving data-related issues will not only improve the ECRs efficiency but also help the interdisciplinary research centers by ensuring their position at the forefront of research and help equip the next generation of interdisciplinary scientists to handle the rapidly increasing amount of data available (Supplementary Table 3). We identified four broad barriers related to data:

(A) Data communication. Communication barriers hinder the smooth sharing and coordination of data between different disciplines. Challenges arise in dissemination and publication of research activities that integrate the expertise of many domains, such as marine biology, chemistry, ecotoxicology, computer science, including reporting of results, and technical language.

(B) Data quality and format. All the ECR participants experienced challenges in integrating data for interdisciplinary research, despite having access to the datasets they needed.

(C) Data access and infrastructure—ECRs may not be in possession of their data, instead relying on institutes, senior researchers, and collaborative companies to access their databases and platforms. In some cases, ECRs may rely on the willingness of different project stakeholders for data access and later feel indebted to them (e.g., eternal inclusion on project ideas, papers). Furthermore, in our experience, database management is not the primary priority of project stakeholders, and often only few people know the nature of data (e.g., metadata). To meet the international standards of high impact work, addressing these issues is inherently crucial to ECRs’ work.

(D) Data handling. Traditionally, data acquisition was a manual process, especially within biology. “Big data” has become a mainstay of research due to advancement in technology, particularly sensors and remote observations, and exponential growth in internet capabilities and various open and online data platforms for visualization and analytics. The use of such datasets and platforms requires big data skills as well as knowledge of data security. ECRs therefore need to update and maintain these skill sets but are seldom provided with training opportunities to do so.

Practical Causes

With regard to data communication barriers (A), data collection and storage are often not designed for collaborators in different subfields to understand and use, and ECRs often lack sufficient knowledge about other topics and tools to share data in ways meaningful outside their own disciplines. Data quality and format (B) became a barrier for ECRs working with inherited data where, despite substantial efforts in the past to standardize and clean datasets by different researchers, data inconsistencies could not be eliminated. Furthermore, legacy data from senior researchers or online databases inherit errors that new recipients are unaware of. Regarding data access and infrastructure (C), the lack of transparent and replicable routines for data management and storage often prevents the use of existing data. Practical causes of barriers related to data handling (D) include a lack of common framework in open and online data platforms that enable interdisciplinary usage of data. Finally, in some overlap with the temporary and short-term contract barriers, time constraints for ECRs are an overarching practical cause of the interdisciplinary data-related barriers above. For example, reliable and relevant data acquisition often relies on manual sampling, a time-consuming, often seasonally limited process, and data cleaning, management, and handling take time to master when considerations must be made for use by other disciplines.

 Structural Causes

(A) The discipline-specific organization of universities inhibits interdisciplinary discussions and development of a common language between disciplines. (B) Past data cleansing efforts are not being circulated and shared in professional circles (Ma et al., 2018), and the absence of institutional frameworks for data collection and format leads to inconsistent entries or data exclusion. (C) There is a lack of integrative open and online data platforms, and decisions are yet to be made regarding who should be responsible for dealing with such challenges: individual researchers, ECRs, research centers, external companies handling external servers, universities, or governments (Durden et al., 2017). Therefore, ECRs need the specific support from project stakeholders and universities to establish networks with big data and data security specialists. (D) There is a lack of recognition of the importance of developing skill sets for handling big data across disciplines and lack of institutional capacity available to train ECRs. Large-scale data science initiatives can help to maximize the use of interdisciplinary data for both individual researchers and the research community as a whole by providing concepts, analytical tools, and training materials (e.g., the Big Data to Knowledge initiative of the National Institutes of Health for biomedical big data; Margolis et al., 2014). Such initiatives will likely disproportionately improve ECRs’ data-related challenges.

 Systemic Causes

(A) Traditional division of academic disciplines continues to hinder smooth communication of data and interdisciplinary results. For example, professional societies and publication outlets are often organized by a specialist topic and may not promote interdisciplinary content or have trained interdisciplinary editors and reviewers, who can translate the languages of different disciplines and uphold the quality of interdisciplinary research (McLeish and Strang, 2016). (B) We noted a lack of research funding and human resources invested in continuous monitoring programs and long-term data collection. (C) The conflicts of interests between the scientific community, universities, institutes, researchers, and project stakeholders hinder the data acquisition process of ECRs, for example through access to potential data sources. (D) The lack of a common data framework established by international regulatory bodies.

 Concluding Thoughts

Interdisciplinary research centers are well-positioned to both lead work to solve complex ocean challenges and to share knowledge through collaborations between public, private, academic, and community groups. We encourage researchers tackling global environmental challenges to increase collaboration across fields but also across career stages. In particular, we encourage more senior researchers and institutes to include and support ECRs in their long-term funding planning, their research networks, and their active research to help overcome the above-described barriers (Supplementary Tables 1–3).

Finally, as ECRs in Norway, we recognize our privilege in earning a salary through our research that enables us to live comfortably without the necessity of a second job, and with a reasonable level of job security for the duration of our contracts. These conditions contribute to a better work environment than is the case for many ECRs globally. It is likely that ECRs at other research centers, within and outside of Norway, will experience additional barriers and may differ in terms of priorities (for limitations of this study, see Supplementary Material: Limitations of this study). In sum, we consider that the barriers highlighted in this article are likely to be close to baseline that is applicable to ECRs around the world (Table 1). We suggest that shorter research visits and exchanges with partner sites could be explored to replace contractual relocation during temporary and short-term contracts (Barrier 1). This will continue to encourage knowledge transfer as well as enable ECRs to establish successful interdisciplinary projects at a “home institute.” Creation of interdisciplinary strategies and infrastructure for collaboration by institutions could enable knowledge sharing both within and between institutions, improve access to methods within the research community, and facilitate networking opportunities for ECRs (Barrier 2). Improved data management standards and associated training at all career stages will reduce data-related barriers to interdisciplinary research for ECRs and all levels of a research organization (Barrier 3). We hope our perspective will help to improve the work and working conditions for ECRs in interdisciplinary settings and ultimately improve the search for solutions to complex ocean challenges.
