Your vessel will be equipped with two vessel-mounted ADCPs, a CTD, and can collect underway data of temperature and salinity from 2 meters below the hull of the ship. In addition, you can deploy up to 30 Argo floats and/or 30 surface drifters. A detailed plan of your route, timing and required instruments needs to be sent in for approval/grading. \n",
