FLEET AND MATERIAL AND TECHNICAL BASIS Research Vessels
Research Vessels

Research vessels Atlantida and Atlantniro allow conducting a wide scope of oceanological and biological surveys in any area of the World Ocean. The vessels were built in Stralsund (Germany) in 1987.

Crew number of each vessel accounts for 40 persons, 11 scientific specialists including. Participants of expeditions occupy single- or double-berth air-conditioned cabins. Eight research laboratories (hydrological, hydrochemical, hydroacoustic, ichthyological with a 9-square metre aquarium, hydrobiological, technological, geological and benthos, and laboratory for satellite observations) are available. Sea water, plankton, benthos and bottom ground are sampled with three hydrological winches. Scientific discussions can be held in comfortable conference hall.

Each vessel is equipped with pelagic and bottom trawls and is able to conduct trawling operations at the depths to 1000 m (Atlantniro) and 1300 m (Atlantida). Catch can be processed into fish meal at a fish meal plant.

Samples are frozen and stored in the 45-cubic metre refrigerator.

To improve maneuverability the vessels are provided with bow and stern maneuvering gears.

Hydroacoustic equipment, used to assess biomass of pelagic fish species, includes a modern echometric complex, being up to the world standards in force.

A set of instruments for environment studying includes:

  • water surface temperature indicator;
  • Doppler sonar current and vessel speed indicator;
  • hydrophysical sounding complex to measure water temperature and salinity, dissolved oxygen and chlorophyll-A content to the depth of 3000 m;
  • hydrochemical complex to determine concentrations of biogenic elements;
  • a special station to receive and process sea surface satellite imagery.

The hydrological laboratory is provided with equipment allowing making a primary processing of plankton and ichthyoplankton samples. The ichthyoplankton laboratory is provided with equipment allowing making biological analysis of fish and invertebrate catches as well as to observe hydrobionts kept in the aquarium. On the whole, the vessels have any possibility to expand directions of exploratory work depending on research problems under investigation.
