Geochemical-physical coupled study of the modern Arctic Ocean: GEOTRACES-ARCTIC

Objective

Climate-driven alterations of the Arctic Ocean (sea ice cover, hydrography, circulation) strongly influence biological productivity and ecosystem structure. At present, our ability to evaluate the full impact of these changes and predict their future trajectory is limited by a poor understanding of the interacting chemical, physical and biological processes which shape the functional characteristics and resiliency of Arctic waters. To bridge this critical knowledge gap, a pan-Arctic field study (Arctic-GEOTRACES) is being coordinated between Canada (2015), US, Germany and France to generate a quasi-synoptic database of biogeochemical tracers in relation to circulation and ecosystem structure and productivity. The Canadian program involves 28 investigators including biological, chemical and physical oceanographers, experimentalists and modelers.
Fully integrated in this program, the proposed research focuses on tracers of ocean circulation and land/ocean chemical exchanges (Rare Earth Elements, ENd, 230Th, 231Pa), both impacted by climate change in the Arctic. It will be conducted on the Canadian section, from the Canada Basin to the Labrador Sea, and consists of a three-step approach:
1) Modelling study of Arctic Ocean dynamics, including off-line Lagrangian analyses to refine the sampling strategy for the tracers above-mentioned;
2) Measurements of these tracers on the Canadian section to specifically investigate land-ocean exchanges and circulation;
3) Integration of these data into a fine resolution model coupling circulation, sea ice dynamics and biogeochemical processes to refine our understanding of circulation and to quantify land-ocean margin chemical exchanges of bioactive or water mass fingerprinting chemical elements.
Besides enriching international databases, results from this program will provide foundational information critical for sustainable development in the Arctic.

Keywords

Project’s keywords as indicated by the project coordinator. Not to be confused with the EuroSciVoc taxonomy (Fields of science)

Programme(s)

Multi-annual funding programmes that define the EU’s priorities for research and innovation.

Topic(s)

Calls for proposals are divided into topics. A topic defines a specific subject or area for which applicants can submit proposals. The description of a topic comprises its specific scope and the expected impact of the funded project.

Funding Scheme

Funding scheme (or “Type of Action”) inside a programme with common features. It specifies: the scope of what is funded; the reimbursement rate; specific evaluation criteria to qualify for funding; and the use of simplified forms of costs like lump sums.

Net EU contribution

Net EU financial contribution. The sum of money that the participant receives, deducted by the EU contribution to its linked third party. It considers the distribution of the EU financial contribution between direct beneficiaries of the project and other types of participants, like third-party participants.
