both inside and outside the WGOMC. Five sites were investigated in the two
year portion of the WGOMC, with three to five ROV stations/site, and four
sites in the actively trawled Kettle, with three ROV stations/site. All
sessile, or weakly mobile, invertebrates were identified and quantified in
each ROV transect in frames where the ROV was positioned on the bottom. Due to
unequal numbers of frames in some transects, numbers were standardized to 50
frames. Non-parametric multi-dimensional scaling (NMDS) was used to
investigate similarities in epifaunal species diversity and abundances. ANOSIM
analysis found a p-value of 0.08, thus our plot suggests a weakly significant
partitioning between closed and open stations.";

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 (external link) Data Access Protocol (DAP) (external link) and its selection constraints (external link).

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.
