String acquisition_description
"The convention is the zero height, or zero depth is the bottom of the
snowpack.
Snow pits were conducted to measure the temperature, salinity, density and
\\u00ef\\u009d\\u201e18O profile through the snow pack as well as a visual
description of grain size, crystal form and hardness of each layer of snow.
Many of the sites had an ice surface that was below freeboard due to snow
loading. This created a salty slush layer on top of the sea ice that had
salinities well above the salinity of seawater and were 10-20 cm thick in
places. This slush layer also had a wicked layer of snow above it where the
snow was wicking the brine up into the snow pack, 10 cm in places.";

Physicists, biologists, and chemists must make use of data collected during U.S. GLOBEC field programs to further our understanding of the interplay of physics, biology, and chemistry. Our objectives require quantitative analysis of interdisciplinary data sets and, therefore, data must be exchanged between researchers. To extract the full scientific value, data must be made available to the scientific community on a timely basis.";

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.
