NetCDF Data Format

OceanSITES uses NetCDF (Network Common Data Form), a set of software libraries and machine-independent data formats. The OceanSITES data managment team has developed an implementation of NetCDF for the data sets. Please consult the Data Format Reference Manual for details.

Data Flow

The OceanSITES data flow is carried out through three organizational units: Principal Investigators (PI), Data Assembly Centers (DAC), and Global Data Assembly Centers (GDAC). In general, a PI provides the data and metadata information to a DAC, which formats this information into the OceanSITES file format and passes it on to the GDAC.

Data Users Guide

The OceanSITES data users guide was developed by Dr. Matthias Lankhorst at Scripps Institution of Oceanography, University of California San Diego. Full document is here.

The GDACs are the primary portal for OceanSITES data and members of OceanSITES must eventually submit their data to a GDAC. Detailed information on each OceanSITE can be found by searching the map.
