String acquisition_description
"Actual sampling location varied slightly between years and may be obtainable
from support contractor records. \\u00a0Approximate location of sampling was
McMurdo Station, Antarctica (77\\u00b051\\u203214\\u2033S,
166\\u00b028\\u203207\\u2033E). The number of measurements varied between
different years from 1 to 20. \\u00a0 All data were collected within an area of
approximately 0.28 km2, at a standard suite of 16 stations along a 3000 m
distance, and five stations across an orthogonal 1000 m distance.
At each station, small holes were drilled through the ice and the thickness
measured using a meter tape with a lever-arm that held the zero-point against
the bottom of the fast ice. Thickness was measured for solid ice and did not
include underlying brash ice or frazil ice, nor overlying snow.
Notes:
1999 began collection of additional data on time of day and snow depth
2003 began collection of additional data from shipping channel sites
2006 stopped collection of shipping channel site data, began collection of
additional data on ice temperature profiles
2010 did not collect ice temperature profile data.
For access to additional data that are available but not transcribed into this
data set; please contact authors to obtain access.";

"Extracted from the NSF award abstract:
The research project investigates the importance of top down forcing on pelagic food webs. The relatively pristine Ross Sea includes large populations of upper-level predators such as minke and killer whales, Adélie and Emperor penguins, and Antarctic toothfish. This project focuses on food web interactions of Adélie penguins, minke whales, and the fish-eating Ross Sea killer whales, all of which exert foraging pressure on their main prey, crystal krill (Euphausia cyrstallorophias) and silver fish (Pleuragramma antarcticum) in McMurdo Sound.
The investigators used a video- and acoustic-capable ROV, and standard biological and environmental sensors to quantify the abundance and distribution of phytoplankton, sea ice biota, prey, and relevant habitat data. The sampling area included 37 stations across an 30 x 15 km section of McMurdo Sound, stratified by distance from the ice edge as a proxy for air-breathing predator access. This study will be among the first to assess top-down forcing in the Ross Sea ecosystem and will form the basis for multidisciplinary studies in the future.

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.
