Title
Assessing the Response of Marine Macro- and Micronutrient Bioavailability and Cycling to Arctic Sea-Ice Loss
General information
Understanding the effects of sea-ice loss on Arctic marine ecosystems
The EU-funded ICEotopes project will develop a multi-tracer approach based on innovative isotopic tracers sensitive to nutrient sources and cycling to be determined in snow, sea ice and seawater obtained from the year-round MOSAiC initiative and from multiple summer cruises to the Arctic Ocean. Combining established and new analytical techniques in trace element and isotope geochemistry and conducting laboratory-controlled sea-ice growth experiments will take advantage of cutting-edge knowledge in tracer development and behaviour without compromising seasonally and spatially constraint dataset. Results will provide a deep understanding of the effects on, and feedback within, Arctic marine ecosystems due to sea-ice loss, reduce uncertainties associated with bioengineering-inspired carbon sequestration efforts and complement Europe's 2020 strategy to tackle Food Security and Climate Action objectives.
