| Summary of measurements |
- -Marine megafauna (seabirds, mammals, turtles) and litter legs.
-Hydrology stations (CTD, taking water samples for nutrients, oxygen, salinity, stable isotope measurements in particulate organic matter, chlorophyll pigments).
-Oblique Bongo-type plankton nets (depths of 200m and 500m).
-Pelagic trawling (250m at night and 100m in daytime).
-Testing the neuston surface surface net (torn the first time deployed).
-Sediment grab (bottom depth 70 m ).
