Edlund. Excellent field assistance was provided by R.J. Richardson in 1972; R.E. Allan, b. Feldbruegge, S. Hotzel, and L.R. Stevenson in 1973; B.G. Green, A.C. Liard and R. Young in 1974. The Atmospheric Environment Service of Environment Canada permitted access to the unpublished Eureka weather station journal in 1973. The field logs were painstakingly transcribed into an orderly body by Theresa Grasby. Result digitizing was supported by PermafrostNet Theme 1.";

String summary "To quantify the ground volumes in the Western Fosheim Peninsula, Ellesmere Island (NU, Canada), 152 boreholes were drilled to depths of 1 to 8 meters from 1972 and 1974. This borehole was drilled on 1973-06-19 with a hand-held drill near Eureka and is 0.9 m deep. The dataset describes soil stratigraphy, volumetric ground ice content, and surface deposits. Volumetric ice content was determined with a combination of visual estimates and laboratory measurements.";

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.
