Continuing the Beaufort Gyre Observing System to Document and Enhance Understanding Environmental Change in the Arctic
This Arctic Observing Network (AON) project will conduct Beaufort Gyre Observational System (BGOS) operations begun in 2003 during 2009-2014 to document the unprecedented changes in sea ice and ocean parameters that are presently occurring in the Beaufort Gyre (BG) region. The project will measure t...
