Sampling equipment for continuous observations (during steaming)
- Echosounders with vessel-mounted transducer transmitting at 5 frequencies on same acoustic axis
- Surface plankton recorder and chlorophyll recorder
Sampling equipment for point sampling (data collection at selected stations)
- Mid-water trawls and nets of different sizes and designs (large pelagic trawls, macrozooplankton trawl, Multinet)
- ROV (remotely operated vehicle) and landers
- Echosounders of various designs/characteristics (hull- and keel-mounted, and towed vehicle transducers)
