Abstract:
Arctic sea ice extent reached another historical record low in summer 2012. More importantly, perennial sea ice extent in 2012 set the new record low in the long period that extends back to the last half of the 20th century as observed by a combination of long-term measurements acquired by ocean buoys and decadal data acquired by satellite scatterometers. To investigate impacts of sea ice reduction on atmospheric chemical processes, we conducted the BRomine, Ozone, and Mercury EXperiment (BROMEX) in March-April 2012 around Barrow, Alaska. We present an overview of BROMEX and highlight results to document sea ice change and chemical processes. We found a large number of bromine explosion events occurred in the BROMEX area where seasonal sea ice dominated.
