eWOCE Home (DVD)

Profile and sequence data from most WOCE data streams have been compiled in integrated, global or basin-wide data sets. When used with the Ocean Data View (ODV) visualization software, this compilation constitutes an Electronic Atlas of WOCE Data that permits graphical display and interactive analysis of the data in many different ways. With extensive interactive controls and the capability to add a wide variety of derived quantities, this electronic atlas complements the printed atlases that are now in preparation.

In addition to the eWOCE data collections, this disk also contains installation files and runtime environments for version 1.2 of the multi-platform Ocean Data View software for Windows, Linux, Solaris, Irix and Mac OS X systems. The runtime environments allow running ODV directly from the disk without having to install the software first. The data collections on this disk are platform independent and can be used on all ODV supported systems. Newer ODV versions or versions for additional platforms might be available at the time when this disk is distributed. Please visit the ODV web page for latest information.

An eWOCE Gallery containing more than 350 property plots along sections from the WOCE Hydrographic Program (WHP) is also included on this disk. The gallery figures are accessed through interactive maps using your web browser. No additional software installation is required for viewing the gallery plots.

The Alfred Wegener Institute for Polar and Marine Research in Bremerhaven conducts oceanographic, atmospheric and ice research in polar and sub-polar areas. Some WOCE WHP lines in the Southern Ocean were carried out with the AWI icebreaker Polarstern.

The eWOCE data files are in binary format for use with the Ocean Data View (ODV) software. The ODV format allows dense storage and fast data access, even for very large data collections. To use the eWOCE data files you run ODV either from an ODV installation on your computer or from the runtime environment on this disk. The data are located in subdirectory data and are organized by DACs:

Directory	Data
cmdac	Velocity and hydrographic data for more than 1300 moored current meters from the Current Meter Program.
pfloat	More than 31,000 temperature and salinity profiles from more than 1600 profiling floats.
sadcp	Shipboard ADCP velocity profiles for more than 240,000 stations and 540 cruises from the ADCP Program.
sl-delay	Hourly sea level data for 161 stations from the delayed mode Sea Level Program (1900-2000).
sl-fast	Hourly sea level data for 129 stations from the fast-delivery Sea Level Program (1985-2001).
sss	Sea-surface temperature and salinity data from the Sea Surface Salinity Program (>400,000 samples).
svp	Trajectories and velocity data for more than 12,000 drifters from the Surface Velocity Program (daily data organized by years, 1979-2000).
whp	Hydrographic, nutrient and tracer data from the WOCE Hydrographic Program (>18,000 stations, separate data collections for bottle and CTD data).
woce-ssf	Trajectories as well as velocity and temperature data for 1040 floats from the Subsurface Float Program.
woce-uot	More than 1 million temperature and salinity profiles from the Upper Ocean Thermal Program (organized by ocean basins; separate data collection for high density lines).

Ocean Data View has built-in support for WOCE and COARDS/CF compliant netCDF files. WOCE data for wind, sea-surface temperature and sea-surface height from satellites as well as meteorological data for WHP lines can be accessed directly from the netCDF files in the respective DAC data directories (sat_mwf1, sat_mwf2, sat_sst, sat_sl, wocemet, woceflux).
