Abstract

Dimethylsulfide (DMS) and pigment samples were taken over two months (October–November 1990) in the Bellingshausen Sea, Antarctica, as part of the Icecolors’ 90 ozone-hole cruise. During this period, a large ice-edge bloom of Phaeocystis developed over an extensive area. To estimate DMS production over the entire bloom, CTD casts provided samples over depth, while transects were taken following the ice edge, and from heavy ice to the open sea. Together, these data provide a three-dimensional overview of DMS production. DMS measurements correlate well with in vivo measurements, and with the presence of Phaeocystis. An estimate was made of DMS production over the duration of an ice-edge bloom.
