the IEH format.

Routine oceanographic sampling within the California Current System has 
occurred under the auspices of the California Cooperative Oceanic Fisheries 
Investigations (CalCOFI) since 1949, providing one of the longest existing 
time-series of the physics, chemistry and biology of a dynamic oceanic 
regime.

Using tabledap to Request Data and Graphs from Tabular Datasets

tabledap lets you request tabular data (for example, buoy data) and graphs of tabular data, via specially formed URLs.
The URLs specify everything: the dataset, the desired file type for the response, and the subset of data that you want to receive.
You can form these URLs by hand or with a computer program,
or (much easier) you can use the dataset's "Data Access Form" (oriented to requests for data)
or the dataset's "Make A Graph" form (oriented to requests for graphs and maps),
both of which generate the URL when the form is submitted.
tabledap is a superset of the OPeNDAP DAP constraint protocol.

tabledap request URLs must be in the form
   http://coastwatch.pfeg.noaa.gov/erddap/tabledap/ datasetID fileType {?query}
For example,
   http://coastwatch.pfeg.noaa.gov/erddap/tabledap/pmelTao.htmlTable?longitude,latitude,time,sea_surface_temperature&longitude>180&longitude<180.2&latitude>0&latitude<0.2&time>2007-06-01T00:00:00Z

For details, see the tabledap Documentation.
