The task of Global Temperature-Salinity Profile Program (GTSPP) is to create a
complete data and information base of ocean temperature and salinity data
captured both in real-time and submitted in delayed mode. The goal is to
construct a database of both the highest quality and the most complete salinity
and temperature data available. ... Both real-time data transmitted over the Global Telecommunications
System (GTS), and delayed-mode data received by the NODC are acquired
and incorporated into a continuously managed database. Countries
contributing to the project are Australia, Canada, France, Germany,
Japan, Russia, and the United States.
Canada's Marine Environmental Data Service (MEDS) leads the project,
and has the operational responsibility to gather and process the
real-time data from the GTS. The quality control procedures used in
GTSPP were developed by MEDS.
NODC maintains the global database by adding the real-time data
supplied by MEDS. NODC also adds delayed-mode data after performing
the same data quality tests as MEDS.
In addition to MEDS and NODC, 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, Industrial and Research Organization (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 Experiment (WOCE,
which GTSPP supports.
