3. Call Topic: Research Priorities in Polar Regions
Proposals must contribute to addressing at least one of the following key research challenges in the polar regions:
- Sea Ice and Polar Oceans in the Climate System: Understanding the properties and dynamics of the sea ice covers and polar oceans and their mutual interaction, their variability at all time scales and their relations to the atmosphere and land is essential to evaluate their role in shaping regional and global climate and major biogeochemical cycles. This includes determining the conditions of occurrence of extreme events such as marine heat waves as drivers of sea ice retreat, the role of sea ice in the Earth’s surface energy balance, the causes of changes in ocean bottom waters properties in relation to their source waters and their impact on the global overturning circulation, the biogeochemical ocean processes in relation to nutrient cycling, ocean carbon uptake, or the release of greenhouse gases from under-ice waters.
- Polar Ice Sheets, Glaciers and Sea Level: Understanding the behavior of the polar ice sheets and glaciers is essential to narrow down the uncertainties on their contributions to global sea-level rise under current and future climate scenarios, including risks of possible collapse in the future. Focus should be put on understanding the dynamics of the Greenland and Antarctic ice sheets, including the impact of subglacial processes on the ice flow, the ice sheet mass balances, and the leading processes controlling their stability, and on monitoring the polar glacier mass balance and retreat in response to global warming.
- Terrestrial Carbon Cycle and Permafrost: Investigating the terrestrial carbon cycle in polar regions, particularly the role of permafrost and polar ecosystems in storing and releasing carbon, is essential to understand the implications for the atmospheric greenhouse gas concentrations and potentially global warming. This includes understanding the permafrost dynamics, distribution and state in Arctic regions, including events of rapid thawing, and quantifying carbon dioxide and methane fluxes from permafrost regions and possible feedback mechanisms.
- Polar Ecosystems and Biodiversity: Understanding the structure, function, and biodiversity of polar ecosystems and how these are affected by environmental changes across different geographical sectors and habitats, including the cumulative effects of multiple drivers, is essential to plan for improved management of these unique ecosystems. Focus should be put on the drivers and characterization of changes, possible occurrence of thresholds or irreversible changes, the connectivity with the lower latitudes and the impacts of human activities.
- Atmosphere dynamics and chemistry: Investigating the atmosphere dynamics and processes in polar regions and their influence on local and global climate systems is essential to improve regional and global climate projections and to plan for the extent of regional and global warming, including changes in extremes in the polar regions and beyond. Focus should be on characterizing changes in weather systems, clouds, and precipitation in the polar regions, understanding the role of clouds in the energy balance and major climate feedbacks in the polar regions, including the major cloud-aerosol feedback, the unique polar atmosphere chemistry, and the sources, pathways and impacts of atmospheric pollutants.
- Paleoclimate Processes and Variability: Collecting and analyzing ice and sediment cores and reconstructing past climate conditions in polar regions is essential to improve understanding of long-term trends and natural climate variability, including past glaciations, ice sheet extent and retreat patterns, and to inform climate projections. This includes integrating multiple proxy data sources to create comprehensive reconstructions of past climate variability and its drivers.
- Humans, societies and global changes: Assessing the impacts of global changes on humans and societies in the polar regions is essential to develop strategies for adaptation and resilience. Focus should be put on understanding the socio-economic impacts on Arctic communities, including cumulative impacts, on livelihoods, health and well-being and adaptation pathways based on co-production of indigenous and scientific knowledge, the contribution of economic development and innovation to welfare, the interdependency between subsistence economy and industrial activities, and impacts on education and schooling trends.
4. Eligibility Criteria
Proposals for access received by the notified submission date will only be accepted for evaluation if they meet the following Eligibility Criteria:
1. Affiliation:
a) The user group leader, and at least the 80% of the users must work in countries other than the country(ies) were the legal entity operating the requested infrastructure is based (when the infrastructure is composed of several research facilities, operated by different legal entities, this condition must apply to each facility), except when access is provided by an International organisation, the Joint Research Centre (JRC), an ERIC or similar legal entities with international membership.
b) User teams with more than four users must include researchers from at least two different countries.
2. Expertise: The user group leader must have the appropriate expertise to lead the research at the requested research infrastructure.
3. Duration of the period of access to RIs: The maximum duration of granted access at a RI is limited to the units of access offered in POLARIN and must in any case be less than three months.
4. Key research challenges: Proposals must contribute to addressing at least one of the key research challenges in the polar regions as detailed in the call text. More information available above.
5. Dissemination: Only user groups that are allowed and willing to disseminate the results they have generated under the project are eligible for access (unless the users are working for SMEs).
6. Data policy: User groups must agree to comply with the POLARIN data policy.
The non-fulfilment of any of the previous criteria implies non-acceptance of the proposal for further evaluation.
5. Access modalities
POLARIN provides Transnational Access (TA) free of charge to research infrastructures for selected user groups. Transnational access can be either in-person (hands-on) or remote.
In-person access means free of charge, transnational (or cross-border) access to research infrastructures or installations for selected user groups. The access includes the use of the RI, and the logistical, technological and scientific support and the specific training for researchers using the infrastructure.
Remote Access is a form of Transnational Access in which the user(s) do not visit the infrastructure/installation physically themselves; instead, the users are either provided with reference materials or samples, get access to a high-performance computing facility, or receive the data from the study that the staff of the infrastructure/installation has conducted according to their research plan and protocol.
It is also possible to combine in-person and Remote Access, meaning that users physically visit the station and set up the required field experiments/monitoring, after which study continues by using Remote Access.
6. Infrastructures offering access in POLARIN TA Call 2025
Forty-nine (49) of the POLARIN RIs are offering Transnational Access in the 2024 Call for Proposals. Detailed information about the RIs and their conditions for access can be found on the POLARIN website . Map-based information on the RIs can be found from INTERACT GIS (Arctic terrestrial RIs), PolarDex (Antarctic RIs and vessels), and individual websites of the RIs.
* for simplification, in this table we use the terms TA as in person access, RA as remote access, TA/RA both in person and remote access.
