The Northwest Fisheries Science Center's Fishery Resource Analysis and Monitoring Division (FRAM) completed the sixth in an annual series of groundfish bottom trawl surveys in 2003. The survey was conducted June 24 to October 23, 2003 and targeted the commercial groundfish resources inhabiting depths of 55 to 1,280 meters [m], (30 - 700 fathoms [fm]) from the area off Cape Flattery, Washington (latitude [lat.] 48°10'N) to the U.S.-Mexican border (lat. 32°30'N) using chartered West Coast commercial trawlers. These ongoing series of annual surveys, conducted by FRAM since 1998, are designed to monitor long-term trends in distribution and abundance of west coast groundfish, especially those species of management concern. The 2003 survey represents the first year in which the depth range was expanded to include both the continental shelf (55 - 183 m) and continental slope (183 - 1,280 m) area and the first year in which a stratified-random sampling design was adopted. In 2003, a total of 574 successful tows were completed out of 643 attempts. Simrad ITI net mensuration data, as well as global positioning system (GPS) navigation data and bottom contact sensor data, used to document performance (e.g. bottom tending), were obtained for most tows. An Aberdeen-style net with a small mesh (2\" stretched measure or less) liner in the codend (to retain smaller specimens) was used to sample fish biomass. Target duration of each tow was 15 minutes. Tow duration was the time between touchdown and lift-off of the trawl net from the seafloor based on readings from bottom contact sensors. Catches were sorted to species, aggregate or other appropriate taxonomic level and then weighed using an electronic, motion-compensated scale. A total of 517 species or families (fish and invertebrates) were identified within the survey area. Although biological sampling effort continues to include Dover sole (Microstomus pacificus), shortspine thornyhead (Sebastolobus alascanus), longspine thornyhead (Sebastolobus altivelis), and sablefish (Anoplopoma fimbria), focus has increasingly shifted to encompass all groundfish species of management concern. Up to 100 length measurements, sex determinations, and individual weights and up to 25 age structures were collected per haul for these species."; String time_coverage_end "2006-01-01T00:00:00Z"; String time_coverage_start "2003-01-01T00:00:00Z"; String title "NWFSC Groundfish Data for U.S. West Coast (2003-2005)"; Float64 Westernmost_Easting -125.86019134521484; } }

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.
