"Since 1992, the Southwest Fisheries Science Center’s Habitat and Groundfish
Ecology team has conducted visual surveys using submersible vehicles to quantify demersal
fish communities in deep seafloor habitats that are typically inaccessible to bottom trawls.
Data are collected from strip transects recorded with video and still cameras. To date, this
georeferenced dataset contains 460,000 individual fishes and 201 taxa, including 242,000
rockfishes (genus Sebastes) comprising 55 species, recorded from more than 2,000 transects
at depths 25 – 1,200 meters, primarily off California. Other data include estimated fish total
lengths, habitat, and in situ depth and temperature. The data have applications for a variety
of research topics, including ecology, distribution modeling, essential fish habitat, and stock
assessment. Videos from the surveys are available for download in mp4 format and
searchable by location, depth, species observed, and other factors.

This project was born out of a need to collect habitat-specific information on
rockfish abundance and ecology that cannot be obtained by traditional survey methods,
such as bottom trawling.";

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 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.

• (easy) You can get data by using the dataset's Data Access Form or Subset form. They make the URL for you.
• (easy) You can make a graph or map by using the dataset's Make A Graph form. It makes the URL for you.
• (not hard) You can bypass the forms and get the data or make a graph or map by generating the URL by hand or with a computer program or script.

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.
