Monthly Summaries of Soil Temperature and Soil Moisture at Oil Contamination Sites in Antarctica

Summary

To determine the effects of oil spills on soil temperature and moisture, soil climate stations were built at existing contamination sites: Scott Base, Marble Point, Bull Pass, and nearby control sites in the Ross Sea Region, Antarctica. Sensors recorded soil temperature, soil moisture, air temperature, relative humidity, solar radiation, net radiation, wind speed, and wind direction. Data extend from January 1999 through December 2001. Data from individual stations are available in tab-delimited ASCII text files. An Excel spreadsheet contains the same data compiled together in a single file. NSIDC currently provides these summary data via FTP; the full soil temperature and moisture data set is available from Ron Paetzold, USDA.

2. Detailed Data Description:

This project investigates the impacts of hydrocarbon spills on soils of the Ross Sea region. Accidental fuel spills in the region occur mainly near scientific stations, where storage and refueling of aircraft and vehicles often results in spills. To determine the effects of spills on soil temperature and moisture, soil climate stations were built at existing contamination sites: Scott Base, Marble Point, Bull Pass, and nearby control sites.

A Campbell Scientific CR10X-2M datalogger records day, time, battery (voltage), and internal temperature. A combination of the following below-ground sensors are attached to the datalogger: Vitel Hydra dielectric constant soil moisture and temperature sensors, Campbell 107 soil temperature sensors, and MRC soil temperature probes.

At Bull Pass, two additional Vitel sensors were installed under a rock at about 40-cm depth. One of the three Campbell 107 temperature sensors was placed under a white rock, one under a black rock, and another between the Vitel sensors under the rock at 42-cm depth.

At Scott Base Oil station, one additional Vitel sensor and six Campbell 107 sensors were placed in an adjacent control site.

Above-ground sensors at all sites include Licor LI200X pyranometer (solar radiation) sensors and Met One wind speed and direction sensors, which are mounted 3 m above the ground. Vaisala HMP45C air temperature and relative humidity sensors are mounted approximately 1.6 m above the ground.

See Active-Layer Depths for a table of active-layer depths at the three primary stations, and graphs of soil temperatures at all six stations.

Format:

Each of the six station files contains average, median, standard deviation, maximum, and minimum values for the following variables. Not all stations have all of these columns.
