    String summary 
"This data contains the locations of some observations of
cold-water/deep-sea corals off the west coast of the United States.
Records of coral catch originate from bottom trawl surveys conducted
from 1980 to 2001 by the Alaska Fisheries Science Center (AFSC) and
2001 to 2005 by the Northwest Fisheries Science Center (NWFSC).
Locational information represent the vessel mid positions (for AFSC
survey trawls) or \"best position\" (i.e., priority order: 1) gear
midpoint 2) vessel midpoint, 3) vessel start point, 4) vessel end
point, 5) station coordinates for NWFSC survey trawls) conducted as
part of regular surveys of groundfish off the coasts of Washington,
Oregon and California by NOAA Fisheries. Only records where corals
were identified in the total catch are included. Each catch sample
of coral was identified down to the most specific taxonomic level
possible by the biologists onboard, therefore identification was
dependent on their expertise. When positive identification was not
possible, samples were sometimes archived for future identification
by systematist experts. Data were compiled by the NWFSC, Fishery
Resource Analysis & Monitoring Division

Purpose - Examination of the spatial and temporal distributions of
observations of cold-water/deep-sea corals off the west coast of the
United States, including waters off the states of Washington, Oregon,
and California. It is important to note that these records represent
only presence of corals in the area swept by the trawl gear. Since
bottom trawls used during these surveys are not designed to sample
epibenthic invertebrates, absence of corals in the catch does not
necessary mean they do not occupy the area swept by the trawl gear.

Using tabledap to Request Data and Graphs from Tabular Datasets

tabledap lets you request a data subset, a graph, or a map from a tabular dataset (for example, buoy data), via a specially formed URL. tabledap uses the OPeNDAP (external link) Data Access Protocol (DAP) (external link) and its selection constraints (external link).

The URL specifies what you want: the dataset, a description of the graph or the subset of the data, and the file type for the response.

Tabledap request URLs must be in the form{?query}
For example,,latitude,time,station,wmo_platform_code,T_25&time>=2015-05-23T12:00:00Z&time<=2015-05-31T12:00:00Z
Thus, the query is often a comma-separated list of desired variable names, followed by a collection of constraints (e.g., variable<value), each preceded by '&' (which is interpreted as "AND").

For details, see the tabledap Documentation.
