"Sea ice cores were collected at 71.2944\\u02daN, 156.7153\\u02daW and

156.7294\\u02daW in May 2018. Sea ice cores were drilled with a MARK II ice
auger (Kovacs Enterprise). The cores were sectioned immediately after
collection with a clean rust-proof, custom alloy bow saw in the field in 5 cm
sections and each was collected in sterile Whirlpak\\u00ae bags. Core sections
were melted at room temperature before volumes were allocated for nutrient,
water isotope, and bulk salinity measurements. Analytical measurements were
made upon sample return to the University of Washington and to the University
of Alaska Fairbanks. Associated temperature profile data were acquired from
the nearby UAF Sea Ice Mass Balance site.";

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.
