"A Sipre 3-inch core barrel was used. The cores were drilled by hand to avoid
contamination by oil and gasoline. Both the ice core length and the ice
thickness were recorded. There was often a discrepancy between these values
due to gaps in the core or the inability to obtain a core sample from the
bottom part of the ice floe.
 
Vertical thin sections were made from the structure cores. These thin sections
were photographed using transmitted natural light and through crossed-
polaroids to analyze the crystallographic structure of the ice. The relative
amounts of granular and columnar ice were determined. Averaging all cores
together there was 66% granular ice and 34% columnar in 2001. In 2002, there
was 78% granular and 22% columnar ice. The structural analysis of the thin
sections was performed by A.J. Gow.";

Polar ice cores contain a record of the past atmosphere - temperature, precipitation, gas content, chemical composition, and other properties. This can reveal a broad spectrum of information on past environmental, and particularly climatic, changes. They can also be used to study bacteria and chlorophyll production in the waters from which the ice core was extracted.";

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.
