The roles of Indigenous youth in environmental research remain largely unexplored with little practical guidance for achieving meaningful engagement in environmental research. This paper aims to characterize the varying types of Inuit youth engagement in environmental research conducted in Inuit Nunangat. Findings were derived from a community-engaged participatory research approach in Mittimatalik (Pond Inlet, Nunavut). Our typology of Inuit youth engagement in environmental research suggests three types of engagements: “participate”, “conduct”, and “control”. Results highlight that Inuit youth who are interested in undertaking their own environmental research projects expect to enhance their knowledge of natural and life sciences more than those who may seek short-term supportive research roles. Strategies employed by researchers seeking to enhance youth research capacity may also vary based on youth wants and expectations. Our findings suggest that there is no one-size-fits all solution. None of the engagement types identified were necessarily and inherently considered better than the others by project contributors, unlike what has been proposed in other, hierarchical, typologies. Our proposed typology contributes to a better understanding of the varying roles that Inuit youth can play in environmental research, as well as inform potential frameworks for enhancing Inuit youth engagement and leadership in research.

Outcrops with conspicuous reddish to yellow-colored clinker, blackish paralava, and blends of both with a breccia-like appearance occur across the Canadian Arctic. We examined such rocks on Ellesmere Island, Banks Island, and the Mackenzie Delta area. These rocks are a product from natural combustion of bituminous shale and low-rank coal seams in Cretaceous and Paleogene host sedimentary rocks, respectively. The main mineral phases of clinker and silicate paralava samples are comprised of quartz + hematite ± feldspars ± cristobalite (or tridymite) ± cordierite–sekaninaite ± clinopyroxene ± sillimanite ± glass. Slag-like iron oxide paralava (74–95 wt.% total Fe2O3) consisting of hematite ± magnetite ± clinopyroxene occur in Paleogene host sedimentary rocks, rich in siderite concretions. The whole-rock geochemical composition of clinker and silicate paralava shows similarities for samples from the same outcrop. Regional and local specific elemental enrichments are mainly inherited from the sedimentary protoliths, which are characterized by volcanogenic input (Paleocene sedimentary rocks) or oxygen-depleted depositional conditions (Upper Cretaceous bituminous sedimentary rocks). Spontaneous combustion could take place when the organic-rich sedimentary rocks become exposed to atmospheric oxygen. This process has occurred at least since the Messinian stage (Miocene) on Ellesmere Island (6.1 ± 0.2 Ma; 40Ar/39Ar incremental heating dating on whole-rock paralava) and continues until now. An active combustion process on scree from a coal seam and clastic Eureka Sound Group sedimentary rocks was observed on Ellesmere Island. [ABSTRACT FROM AUTHOR]

Open top chambers (OTCs) were adopted as the recommended warming mechanism by the International Tundra Experiment network in the early 1990s. Since then, OTCs have been deployed across the globe. Hundreds of papers have reported the impacts of OTCs on the abiotic environment and the biota. Here, we review the impacts of the OTC on the physical environment, with comments on the appropriateness of using OTCs to characterize the response of biota to warming. The purpose of this review is to guide readers to previously published work and to provide recommendations for continued use of OTCs to understand the implications of warming on low stature ecosystems. In short, the OTC is a useful tool to experimentally manipulate temperature; however, the characteristics and magnitude of warming varies greatly in different environments; therefore, it is important to document chamber performance to maximize the interpretation of biotic response. When coupled with long-term monitoring, warming experiments are a valuable means to understand the impacts of climate change on natural ecosystems.

Community leadership in Arctic environmental research is increasingly recognized as one of many pathways to Indigenous self-determination in Nunavut, Canada. While experienced Inuit hunters, trappers, and other recognized environmental knowledge experts are commonly included in research, similar opportunities for Inuit youth to meaningfully engage in environmental research remain limited. Finding ways to increase scientific literacy, particularly among Inuit youth, has been identified as an important step in the continuation of high-quality Arctic environmental research. This paper examines community perspectives on the roles and contributions of Inuit youth in environmental research in Nunavut, barriers that Inuit youth face in becoming meaningfully engaged in field-based environmental research, and strategies for enhancing Inuit youth engagement. Our study was conducted in Pond Inlet, Nunavut, and used interviews, workshops, and observation to gather stories and knowledge from community members about field- and land-based experiential learning pathways. This study found that a complex set of barriers, including a lack of credentials and support systems, among others, may inhibit meaningful Inuit youth engagement in environmental research. Key findings from the study support the view that collaborative land-based research activities can be an effective and meaningful method of enhancing scientific literacy among Inuit youth.

Marine plastic is a ubiquitous environmental problem that can have an impact on a variety of marine biota, such as seabirds, making it an important concern for scientists and policy makers. Although research on plastic ingestion by seabirds is increasing, few studies have examined policies and long-term monitoring programs to reduce marine plastic in the Arctic. This paper provides a review of international, national, and regional policies and long-term monitoring programs that address marine plastic in relation to seabirds in the Arctic countries: Canada, the Kingdom of Denmark (Greenland and the Faroe Islands), Finland, Iceland, Norway, the Russian Federation, Sweden, and the United States of America. Results show that a broad range of international, national, regional and local policies address marine debris, specifically through waste management and the prevention of pollution from ships. However, few policies directly address seabirds and other marine biota. Further, policies are implemented inconsistently across regions, making it difficult to enforce and monitor the efficacy of these policies given the long-range transport of plastic pollution globally. To reduce marine plastic pollution in the Arctic environment, pan-Arctic and international collaboration is needed to implement standardized policies and long-term monitoring programs for marine plastic in the Arctic and worldwide.

Subsistence is the basis for food access for Inuvialuit in the western Canadian Arctic and has strong economic, dietary, and cultural importance. Inuvialuit harvest beluga whale (Delphinapterus leucas (Pallas, 1776)) from the eastern Beaufort beluga population during summer months within parameters established through co-management. Over the past thirty years there has been a dramatic decline in the number of beluga harvested by Inuvialuit from the community of Aklavik, Northwest Territories. This paper investigates the potential drivers of change, both social and ecological, affecting the beluga harvest. Data were collected using 32 semi-directed interviews and experiential learning. Results revealed that ecological changes, notably coastal erosion at preferred whaling camps and unpredictable and severe weather have made harvesting more difficult, expensive, and often impractical. These changes are being experienced together with social changes including the loss of elders and their knowledge, and changing values and motivations for harvesting beluga. We conclude that no one driver is responsible for the decline in the beluga harvest, but rather it is the result of multiple social-ecological changes operating across scales that affect the feasibility of the harvest and motivation to participate.

Inuit hunters and meteorologists alike pay close attention to weather and weather changes, with deep understandings. This paper describes a long-time research project based in Kangiqtugaapik (Clyde River), Nunavut, where a research team of Inuit and visiting scientists have combined information and knowledge from a community-based weather station network, on-going interviews and discussions, and extensive travel (both Arctic fieldwork and visits to southern universities) to co-produce knowledge related to human–weather relationships and weather information needs and uses in one Nunavut community. The project uses the concept of “HREVs”, human-relevant environmental variables — complex, synthesis variables that, used in conjunction with a host of social variables, assist in informing safe land travel and activities. This work, including linking Inuit knowledge and environmental modeling, can be expanded to not only understand human–weather relationships more broadly and in other locations but also provide insights into the process of building diverse research teams and knowledge co-production.

This communication paper reflects on discussions from a workshop about Indigenous involvement in the peer review and editorial processes. Arctic-based research is undergoing a paradigm shift to include local Indigenous Peoples, their priorities, and knowledge throughout the research process. This special issue is an excellent example; it highlights research involving partnerships between Indigenous and non-Indigenous researchers to support knowledge co-production. Despite this shift, we find little space within the standard peer review and editorial processes for Indigenous Peoples, their perspectives, and knowledge. To discuss this issue, we organized a half-day workshop at the 2019 ArcticNet Annual Scientific Meeting with a diversity of Indigenous and non-Indigenous participants who are involved in Arctic research. The discussions revealed that answering questions about the involvement of Indigenous Peoples in the peer review and editorial processes largely begins by addressing the challenges of achieving equity in the research process generally. Our discussions demonstrated that further conversations are needed and that no single approach will work in all cases, but that there are several concrete actions that researchers, universities, funding organizations, and publishers can take to begin addressing this issue.

This paper documents Inuvialuit traditional ecological knowledge of beluga, including ecology and behavior, hunting techniques, and food preparation under changing climatic conditions in Tuktoyaktuk, NT. Beluga whale (Delphinapterus leucas) is an important food source for Inuvialuit in the western Canadian Arctic, a region that is experiencing dramatic climate change. Data were collected using semi-directed interviews with 17 Inuvialuit beluga harvesters and participant observation. The research found that Inuvialuit beluga harvesters possess detailed rational knowledge of beluga, particularly regarding hunting techniques and food preparation, both which are guided by a moral code about how to behave with respect to beluga. In terms of beluga ecology and behavior, Inuvialuit knowledge is limited to anecdotal reasoning drawing on generalized observations of beluga and the accounts of others. Inuvialuit are experiencing the effects of climate change, but seem to be coping thus far in the context of beluga harvesting but ongoing change in the region may increase the risks associated with hunting and preparing beluga in the future.

If the current rate of climate change continues, the composition, distribution, and relative population sizes of species in the higher latitudes of the Northern Hemisphere are likely to change considerably. Understanding the magnitude of this change requires a well- documented baseline against which to compare. Although specimen-less observations can help augment such a baseline for the minority of organisms that can be confidently identified in the field or from photographs, the vast majority of species are small-bodied invertebrates, primarily arthropods, that can only be identified from preserved specimens and (or) their tissues. Museum staff archive specimens and make them and their data available for research. This paper describes a number of challenges to the goal of thorough documentation of high-latitude arthropod biodiversity and their potential solutions. Examples are provided from ongoing and recently completed research that demonstrates the value of museum specimens and the sharing of their data via global portals like GBIF.org.
