String summary "Zooplankton taxonomic abundance from surface net tows at sampling stations in the Delaware Bay for microplastics research during the fall of 2019 and spring of 2022. Zooplankton were collected using a 0.5m diameter ring net with 200 um mesh fitted with a mechanical flow meter (General Oceanics, Model 2030R) at the net opening and filtering cod-end. Nets were towed for approximately 5 minutes at 1-2 knots. Samples were gently rinsed with filtered seawater into glass jars and preserved in a 10% buffered formalin solution until later analysis in the laboratory where zooplankton taxa were identified and enumerated using a dissecting microscope.";

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/erdGlobecBottle.htmlTable?longitude,latitude,time,bottle_posn,temperature1&time>=2002-08-17T00:00:00Z&time<=2002-08-19T20:18:00Z
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.
