PMEL’s Dr. Trish Quinn led a group of PMEL and JISAO scientists on a recent cruise in the North Atlantic Ocean to assess how ocean biogeochemistry impacts sea spray particles. Quantifying the size and composition of sea spray particles is critical for parameterizing cloud condensation nuclei in climate models.  The particles are generated using the PMEL developed Sea Sweep device that is deployed over the side of the ship to collect samples. 

The study, which ended on June 5, is part of the Western Atlantic Climate Study II (WACS II) and was conducted using the Woods Hole Oceanographic Institute’s R/V Knorr.  For more information please visit PMEL’s Atmospheric Chemistry website.
