Seawater samples were retrieved from depth using standard oceanographic sampling equipment and then collected by vacuum filtration onto 0.2 µm pore size Durapore membrane filters; these were frozen immediately at -80°C. Extraction was performed using a modified Bligh and Dyer (Bligh and Dyer, 1959;...
