1962, British weather vessels measured sea temperature and salinity values from the surface down to as part of their duties. Upper air soundings launched from weather ship E ("Echo") were of great utility in determining the cyclone phase of Hurricane Dorothy in 1966. During 1971, British weather ships sampled the upper of the ocean to investigate plankton distribution by depth. In 1972, the Joint Air-Sea Interaction Experiment (JASIN) utilized special observations from weather ships for their research. More recently, in support of climate research, 20 years of data from the ocean vessel P ("Papa") was compared to nearby voluntary weather observations from mobile ships within the International Comprehensive Ocean-Atmosphere Data Set to check for biases in mobile ship observations over that time frame.
