==Comparison of World Ocean Databases==

The World Ocean Database represents the world’s largest collection of ocean profile-plankton data available internationally without restriction. Data comes from the: (a) 65 National Oceanographic Data Centers and nine Designated National Agencies (DNAs) (in Croatia, Finland, Georgia, Malaysia, Romania, Senegal, Sweden, Tanzania, and Ukraine), (b) International Ocean Observing Projects such as historical [[WOCE|World Ocean Circulation Experiment]] (WOCE) and Joint Global Ocean Flux Study (JGOFS), as well as currently active programs such as [[CLIVAR]] and Argo, (c) International Ocean Data Management Projects such as the IOC/IODE Global Oceanographic Data Archaeology and Rescue Project (GODAR), and (d) Real-time Ocean Observing Systems such as the IOC/IODE [[Global_Temperature-Salinity_Profile_Program|Global Temperature-Salinity Profile Project]] (GTSPP). All ocean data acquired by WDC Silver Spring – USA are considered as part of the WDC archive and freely available as public ___domain data.

The World Ocean Database was first released in 1994 and updates have been released approximately every four years, 1998, 2001, and 2005. The most recent World Ocean Database series, WOD095, was released in September 2009. The WOD09 has more than 9 million temperature profiles and 3.6 million salinity profiles. Table 1.0 is a comparison of the number of stations by instrument type in WOD09 with previous NODC/WDC global ocean databases.

'''==Instrument Types'''==

Ocean profile, plankton data, and metadata are available in the World Ocean Database for

29 depth-dependent variables (physical and biochemical) and 11 instruments types: Ocean Station Data (OSD), Mechanical Bathythermograph (MBT), Expendable Bathythermograph (XBT), [[Conductivity-, Temperature-, Depth]] (CTD), Undulating Oceanographic Recorder (UOR), Profiling Float (PFL), Moored Buoy (MRB), Drifting Buoy (DRB), Gliders (GLD), Autonomous Pinniped Bathythermograph (APB).

'''==Word Ocean Database Products'''==

The data in the World Ocean Database are made available through the on line search and retrieval system known as the WODselect. Another project using the World Ocean Database variables is the [[World Ocean Atlas]] (WOAselect). The WOAselect is a selection tool by which the user can designate a geographic area, depth, and oceanographic variable to view climatological means or related statistics for a given variable at the requested depth for the requested geographic area. The World Ocean Atlas series is a set of gridded (1° grid), climatological, objectively analyzed fields of the variables in the World Ocean Database.
