Vessel Description

The vessel is a dedicated Spanish oceanographic research ship operated under the institutional framework of the Spanish National Research Council (CSIC) and the Spanish Institute of Oceanography (IEO). The vessel was designed and built specifically for scientific research purposes, including fisheries assessment, marine biology surveys, physical oceanography, and environmental monitoring. Her diesel-electric propulsion combined with azimuth thrusters provides enhanced maneuverability and low acoustic noise levels, essential for sensitive scientific operations such as acoustic fish stock assessments. The vessel is equipped with dedicated laboratory spaces, scientific winches, and sampling equipment suited for deep and shallow water research activities. Operating primarily in Spanish and broader European Atlantic and Mediterranean waters, she represents a significant asset in Spain's national oceanographic research fleet.
