It was an annual program with missions in the months of  November - January covering 35 stations in the Gulf Of St. Lawrence. The purpose was to obtain temperature-salinity measurements in the upper 100 m of water from 35 stations in the Gulf of St. Lawrence for preparation of seasonal ice outlook by the Ice Climatology Branch and later the Ice Forecast Central Office of the Department of Environment Atmospheric Environment Service.  The data measured included: profile CTD, dissolved oxygen and nutrient data, oxygen isotope, Ra isotope, sediment cores,  satellite transmitting thermistor buoys to monitor the cooling, and doppler current profiler to measure ice motion and currents.";

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.
