String comment "This product is the result of collating and analyzing fish stomach contents data from the North Atlantic and Arctic Oceans to classify fish into functional feeding guilds based on their diet. Non-metric multidimensional scaling (NMDS) analysis was used to provide information on the differences between fish species and size class feeding traits in relation to one another. The NMDS analysis presents axis scores that offer a more nuanced perspective compared to categorical data (i.e. feeding guilds), of different predator feeding traits. This analysis is part of the process to classify feeding guilds based on predator stomach contents data.

Data Access Protocol (DAP) and its
projection 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.
griddap request URLs must be in the form
https://coastwatch.pfeg.noaa.gov/erddap/griddap/datasetID.fileType{?query}
For example,
https://coastwatch.pfeg.noaa.gov/erddap/griddap/jplMURSST41.htmlTable?analysed_sst[(2002-06-01T09:00:00Z)][(-89.99):1000:(89.99)][(-179.99):1000:(180.0)]
Thus, the query is often a data variable name (e.g., analysed_sst),
followed by [(start):stride:(stop)]
(or a shorter variation of that) for each of the variable's dimensions
(for example, [time][latitude][longitude]).
For details, see the griddap Documentation.
