GTSPP Global Temperature and Salinity Profile Project “A cooperative international program designed to develop and maintain a global ocean T-S resource with data that are as up-to-date and of the highest quality as possible.” “The primary goal of the GTSPP is to make these data quickly and easily accessible to users. ”
