String summary "Fisheries Monitoring in Ocean Wind 01. Two seasonal pre-construction surveys. Twenty tows conducted in the lease area and twenty in the control area each season (160/year total). Tows conducted at three knots for 20 minutes. Trawl data will inform relative biomass (kg/tow) by species, size frequency by species, condition index (length-weight) by species, community assemblage, and gut content of a subset of species. This dataset includes the gut content analysis performed on a subset of the catch.";

Data Access Protocol (DAP) and its
selection constraints.
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
https://coastwatch.pfeg.noaa.gov/erddap/tabledap/datasetID.fileType{?query}
For example,
https://coastwatch.pfeg.noaa.gov/erddap/tabledap/pmelTaoDySst.htmlTable?longitude,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.
