Global Temperature-Salinity Profile Program

The Global Temperature and Salinity Profile Programme (GTSPP) is a cooperative international project that seeks to develop and maintain a global ocean Temperature-Salinity resource with up-to-date and high quality data.

Making global measurements of ocean temperature and salinity (T-S) quickly and easily accessible to users is the primary goal of the GTSPP.

Both real time data transmitted over the Global Telecommunications System (GTS), and delayed-mode data received by NCEI are acquired and incorporated into a continuously managed database.

NOAA's National Centers for Environmental Information (NCEI) performs four functions for the GTSPP: In addition to MEDS and NCEI, three science centers participate in the project by independently evaluating the delayed-mode data sets for the Indian, Pacific, and Atlantic Oceans.

Australia's Commonwealth Scientific and Industrial Research Organisation (CSIRO), the Scripps Institution of Oceanography (SIO), and NOAA's Atlantic Oceanographic & Meteorological Laboratory (AOML) perform this function as Data Assembly Centers for the World Ocean Circulation Program, which the GTSPP supports.
