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 The ocean (also the sea or the world ocean) is the body of salt water that covers approximately 70.8% of the surface of Earth and contains 97% of Earth's water. An ocean can also refer to any of the large bodies of water into which the wo ...

(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

(NCEI) performs four functions for the GTSPP: # Maintains the global database of temperature and salinity data and provides online access to the data. # Adds real-time data supplied by MEDS to the database. # Processes delayed mode copies of data by performing the same data quality tests as MEDS, then adds data to the database. # Prepares monthly data sets and transfers them by network to participants in the U.S., Australia and France, as well as to requestors. In addition to MEDS and NCEI, three science centers participate in the project by independently evaluating the delayed-mode data sets for the Indian,

Infrastructure

The GTSPP consists of four major components: * Global Telecommunication System (GTS): Carries real-time data from ships and buoys in support of the IOC/WMO Integrated Global Ocean Services System (IGOSS). * IODE Data Centers: Contribute data, monitor the project, and distribute products. These are national oceanographic data centers which participate in the
