Equipment

Sampling equipment and technologies on leg 1

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)
  • CTD (profiler for salinity and temperature) and UVP (underwater video profiler)
  • See G.O. Sars website (http://www.imr.no/english/about_imr/vessels/g.o._sars)
    for permanent instrumentation and facilities
