There’re no exact length limits separating the classes so there will be some overlap between classes and selecting size classes will have to come with experience.";

String comment "This is the weight in kgs of anything we took measurements for where we didn’t measure every individual of that species, with the exception of anything sorted into size classes (50 count/class). If there are over 100 individuals of one species and not everything got measured, then everything that got measured gets reweighed and put here. For example, if there’s 20 kgs and well over 100 count of Northern Sea Robins, we measure 100 and get the weight of the 100 we measured. Things are recorded a bit differently if they were assigned a size class. If there is a size class for a species, ALWAYS take the weight of what was measured (by size class) regardless of the count";

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/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.
