The main objective of this project was to assess variability among estuaries in supporting fishery species and other abundant nekton. The project is part of a larger effort of the National Marine Fisheries Service Galveston Laboratory to develop a Comparative Assessment of Gulf Estuarine Systems (CAGES). The nekton abundance data summarized in this report are available at http://data.gcoos.org. This cooperative study with state natural resources agencies was designed to use fishery independent monitoring data and compare historical catches from 4.9-m and 6.1-m trawl surveys. This report provides an assessment of the abundance, length frequencies, and biomass of 14 species of fish and four species of decapod crustaceans that were either abundant in the samples or economically important. The most abundant species in the analysis include bay anchovy, Atlantic croaker, spot, and brown shrimp. Other fishery species of particular interest include Gulf menhaden, white shrimp, pink shrimp, blue crab, spotted seatrout, southern flounder, and red drum. While the years analyzed varied among states, samples from most estuaries were available and analyzed for the years 1986 to 2005. The 24 estuaries analyzed were identified using the Estuarine and Coastal Drainage Areas delineated by the U. S.Geological Survey and listed in NOAAs Coastal Assessment Framework"; String time_coverage_duration "P0Y0M30DT23H45M0S"; String time_coverage_end "1995-12-28T15:09:00Z"; String time_coverage_start "1995-01-03T11:00:00Z"; String title "CAGES_Louisiana_CPUE_Trawl_study_OBIS_MeasurementOrFact_1995"; Float64 Westernmost_Easting -93.36667; }}
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.
