This boat does research. It basically gathers information from the ocean by sampling the water at different depths. They have a device they lower down to the bottom that has many tanks on it. They can open & close these sampling tanks at different depths to sample the waters plankton. They also check PH,temperature,salinity,DO (dissolved oxygen). This data is collected because of fish farms being near by. The Government wants to make sure the environment isn’t being affected adversely by the farms.
