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. Purpose. 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. International contributors. Several countries contribute to the GTSPP. They are: Canada 's Marine Environmental Data Service (MEDS) leads the project, and has the operational responsibility to gather and process the real-time data. MEDS accumulates real-time data from several sources via the GTS. They check the data for several types of errors, and remove duplicate copies of the same observation before passing the data on to NCEI. The quality control procedures used in GTSPP were developed by MEDS, who also coordinated the publication of those procedures through the Intergovernmental Oceanographic Commission (IOC). 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. Infrastructure. The GTSPP consists of four major components:
