Modelling Arctic Oceanographic Connectivity

Connectivity 2021 Report coverOngoing climate change may facilitate increased access to the Arctic region, and potential new economic opportunities, but may also bring potential threats to the Arctic marine and coastal environments. These changes could benefit from more integrated approaches to Arctic marine management, including the consideration of MPA networks designed to aid in the conservation and sustainable use of the Arctic environment. Understanding seascape connectivity in the Arctic Ocean using oceanographic circulation models is one way to support MPA networks and sustainable use of the Arctic Ocean.

Modelling Arctic Oceanographic Connectivity Report

In May 2021, the report on Modelling Arctic Oceanographic Connectivity was appropved at the Arctic Council Ministerial meeting. The report is aimed as a working document and is a contribution PAME’s MPA toolbox by:

  • mapping potential connectivity among populations of key marine species in the Arctic region using biophysical modelling to inform the positioning and nature of conservation measures deployed in a network of MPA
  • describing dispersal distance within the Arctic Ocean, which may be used to infer the minimum size of Marine Protected Areas (MPAs) for sufficient self-recruitment
  • identifying sources and sinks for MPAs and other valuable areas, e.g. fish spawning grounds and juvenile nursery areas
  • identifying major barriers to dispersal and gene flow

Continued project on Modelling Arctic Oceanographic Connectivity, with the inclusion of the Central Arctic Ocean, to further develop PAME’s Marine Protected Areas Toolbox

In 2021 to 2023, PAME will build on the Connectivity Report with a follow up project.
