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."; String time_coverage_end "2022-09-06"; String time_coverage_start "1992-08-22"; String title "FED Demersal Fish and Habitat Visual Survey Query."; Float64 Westernmost_Easting -124.97302104; } }
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").
