World Ocean Database, World Ocean Atlas, and Regional Climatologies
Ocean Climate Laboratory Team/NODC
A quality controlled collection of ocean profiles, plankton tow , and ship-based surface measurements from 1772-present.
Instrument types in WOD
1) Station Data (bottles, thermometers)
5) Towed CTD
6) Profiling Floats
7) Drifting buoy (thermistor chains)
8) Moored buoy (e.g., TAO, PIRATA TRITON)
9) Autonomous Pinniped (instrumented

Up to date, four regional climatologies have been completed and published at NODC web site. Gulf of Mexico (a supplement to the Gulf of Mexico Digital Atlas), the East Asian Seas Climatology, the Arctic and most recently Greenland-Iceland-Norwegian Seas
NODC existing and intended regional climatologies in the Northern Hemisphere in FY12-FY16 (the Nordic Seas Atlas is a collaborative NODC-AARI –University of Bergen project).

The Greenland, Iceland and Norwegian Seas (GINS) – the gateways for water exchange between the North Atlantic Ocean and the Arctic – play a key role in the entire high-latitudinal ocean climate formation and change.
To provide an improved oceanographic foundation and reference for multi-disciplinary studies of the GINS, NODC Regional Climatology Team developed a new set of high-resolution quality-controlled long-term annual, seasonal and monthly mean temperature and salinity fields on different depth levels.

The NWA high-resolution regional climatology is a part of the NOAA-wide Sustained Marine Ecosystem in Changing Climate (SMECC) Project.
NODC Regional Climatology Team1 developed a new set of high-resolution quality-controlled long-term annual, seasonal and monthly mean temperature and salinity fields on different depth levels.
This new regional climatology is based on the World Ocean Database 2013 archive of temperature and salinity from observations spanning over more than a hundred years and incorporates a great deal of new data not previously available.
High-resolution NWA regional climatology provides quality-controlled temperature and salinity on 87 levels with 1/10°x1/10° grid resolution.

At the moment, the “all-time” NWA climatology has been completed on 1/10x1/10° grid. “All-time” means the climatology was compiled using all available data. There will be decadal climatologies compiled for six decades from 1955-1954 to 2005-2012 (the last “decade” has only eight years of data). The decades 1995-2004 and 2005-2012 will be completed by the end of FY14, while earlier decades are due in FY15.
Annual temperature at the surface from NWA regional climatologies with 1°x1°, 1/4°x1/4° and 1/10°x1/10° grid resolution show dramatic improvements provided by high-resolution climatology.
