Advective Pathways of nutrients and key Ecological substances in the ARctic


Twitter: @CAO_APEAR

Retreating Arctic sea ice is expected to change the way the ocean interacts with the atmosphere, which will affect the Arctic ecosystems.

APEAR will help to understand how the sea ice decline and the longer summer season will change the pathways of nutrients which enter the Arctic Ocean from the Atlantic and Pacific.

Another goal is to examine how the differences between parts of the Arctic ecosystem may change. We will combine in situ measurements from MOSAiC fieldwork with ultra-high-resolution computer modelling to quantify current and future changes in the Arctic ecosystems.

This project is co-funded by the German Federal Ministry of Education and Research and by UKRI NERC.

Dr Yevgeny Aksenov, lead investigator of the APEAR project:

Arctic sea ice decline is expected to increase the regional differences between parts of the Arctic ecosystem.

Lead Investigators

  • Dr Yevgeny Aksenov

    Co-lead investigator, National Oceanography Centre (NOC)

    Yevgeny Aksenov is a Senior Research Fellow at the National Oceanography Centre. He is co-lead investigator for APEAR, providing overall management and coordination of the project and leading sea ice and ocean modelling analysis. His research focuses on global modelling of ocean circulation and sea ice dynamics, and in implications for climate and impacts on sea ice and ocean. He is part of collaborative sea ice-ocean biogeochemical modelling studies.
