1. An evaluation device comprising circuitry that compares reference data to measurement data to generate a probability of an existence of a seabed deposit,
wherein the reference data is generated by machine learning,
wherein the reference data comprises reference location data for a known seabed deposit and reference fine particle component measurement data for the known seabed deposit,
wherein the measurement data comprises evaluation location data for a seabed deposit search area and evaluation fine particle component measurement data for the seabed deposit search area,
wherein the reference fine particle component measurement data comprises measurement data regarding microorganisms from the known seabed deposit,
wherein the evaluation fine particle component measurement data comprises measurement data regarding microorganisms from the seabed deposit search area, and
wherein the circuitry outputs the generated probability of the existence of the seabed deposit as navigation information.
