Abundance and size distribution of transparent exopolymer particles (TEP) during a coccolithophorid bloom in the northern Bay of Biscay
The distribution of transparent exopolymer particles (TEP) was investigated during a coccolithophorid bloom in the northern Bay of Biscay (North Atlantic Ocean) in early June 2006. MODIS chlorophyll-a (Chl-a) and reflectance images before and during the cruise were used to localize areas of importan...
