This data set consists of borehole temperatures from different depths gathered by three thermistor strings, which were deployed in three boreholes drilled through the Pine Island Glacier ice shelf, Antarctica. Each string held 16 thermistors along its length spaced at varying distances from each other.
The data are in MATLAB (.mat) format.
Data are available on the FTP site in the ftp://sidads.colorado.edu/pub/DATASETS/AGDC/nsidc0627_truffer/ directory. Within this directory, there are three files: tstring1.mat, tstring2.mat, tstring3.mat. Refer to Table 1 for a list of the variables contained in each file.
Variable | Description |
---|---|
tstringTemp | n x 16 matrix of calibrated thermistor data in °C |
yd | 1 x n array of yearday (yyyddd.dddd). (Example: 2013009.5 would represent noon on yearday 9 of 20913.) All times are UT. |
dx | 1 x 16 array of distance of each thermistor from bottom of string where the bottom of the string is approximately at the ice/water interface. Thermistor 1 is the deepest thermistor. |
lbl | Label string |
The files of this data set range from 14.3 to 155 KB.
The data set has a volume of 374.7 KB.
The data were collected at Piine Island Glacier, Antarctica (75.1° S 100.5° W). Refer to Figure 1 for Pine Island Glacier's location.

Spatial Resolution
Spatial resolution varies from 0 to 110 meters.
Data were collected from 20 Dec 2012 to 10 May 2013.
Temporal Resolution
Temperatures were recorded every two hours.

Sample Data Record
Refer to Figure 2 for an example of the data.

Software and Tools
The MATLAB files can be accessed using MATLAB software.
Data Acquisition and Processing
Three boreholes were drilled using hot water, and a thermistor string was deployed in each borehole. Each thermistor string held 16 thermistors. Thermistor strings 1 and 3 were placed at Pine Island Glacier Site A, and string 2 at Site B.
