• Profile measurements in a horizontal and vertical plane of the physical and chemical properties of the sea
• Locating and charting temperature and salinity fronts
• Measurements of temperature, salinity and tracking of pollutant sources
• Studies of seabed topography and biosphere, all research in shallow and deep water down to 2000 meters and under ice
• Measurements of plankton and smolt using a camera, sonar and echo sounder
• Measurement and smolt counting of fish-stock size using echo sounder, lateral sonar and camera
• Search for fish, benthic species etc.
• Exploration of the sea bed
• Research on the impact of fishing gear
• Research in lakes, e.g. measurements of fish stock sizes and fresh water studies

Fish Farming and Fisheries

• Monitoring of the physical and chemical properties around sea cages
• Surveying and monitoring of sea cages to prevent accidental releases of fish
• Surveying of sea cages to prevent the attack of seals
• Surveying of artificial reefs used as breeding grounds in coastal fish farming
• Searching schools of pelagic species, like capelin, herring, mackerel etc.
  Offshore Industries
• Surveying underwater pipes, cables and oil extraction installations

Military/Police/Coast Guards

• Mine counter measures
• Surveying
• Search and rescue operations
• Coastal drug control
• Application as a delivery vehicle

Environmental Research and Monitoring

• Environmental assessment in sensitive areas, prior to major projects
• Ocean floor studies prior to sewage outlet construction
• Mapping of inshore areas that survey vessels cannot enter. Many maps lack detailed information and description of the inshore coastline, due to lack of research tools and methods in early stages of surveying
• Mapping of shipwrecks on the ocean floor. Uncharted shipwrecks pose a threat to fishing gear
• Surveying of bridge and harbor constructions, monitoring of shifting sediment in harbor entrances
• Tracking of pollutant sources. Gavia can be equipped with various sensors for pollutant sensing.
