RV Aranda is a modern, ice-reinforced research vessel owned by the Finnish Environment Institute SYKE. Even if  planned and constructed for Baltic Sea research, she is able to operate in all seas. Aranda has made scientific expeditions i.a. to Antarctic waters and the Northern Atlantic.

Aranda was thoroughly renovated in 2016-2017, in terms of hull shape, deck area, laboratories and instrumentation.

The vessel is adapted to year-round multidisciplinary marine research, including biology, physics, chemistry and geology of the sea. The well-equipped laboratories and advanced computer systems facilitate sample treatment and data analysis under way.

The manoeuvrability of Aranda has been dimensioned for demanding research work, the ship being able to stay exactly in position at a station with the aid of DGPS and DP systems. Aranda has the equipment to receive satellite and weather images, and its own versatile weather station.
