The Arctic Ocean is a dynamic place, and climate change is making it even more so. That picture is gradually becoming clearer, thanks to data collected by the Beaufort Gyre Observation System (BGOS), an ocean monitoring network developed and maintained by Woods Hole Oceanographic Institution (WHOI) researchers for nearly two decades. As one of the primary drivers of Arctic Ocean circulation, researchers are closely monitoring this gyre to understand changes in the Arctic region and how it affects the climate at lower latitudes. More than 160 publications have tapped into data from BGOS in recent years, covering such topics as ocean circulation, sea ice changes, and ecosystem and biogeochemistry dynamics. One recent study from the Massachusetts Institute of Technology showed a clear correlation between summer ice melt and the formation of high-energy swirling water masses known as eddies in the Arctic Ocean.
