Antarctic microclimate data


Automatic data loggers are often used to monitor environmental variables such as temperature (of air and soil), humidity, wind speed and radiation in microclimates where experimental or ecological studies are being carried out. Some loggers are only in operation for a few weeks or months while others have been run for several years. Loggers have been sited in a wide variety of locations from the sub-Antarctic (South Georgia), South Orkney Islands (Signy) various Peninsula sites (as far south as Alexander Island - 70S), and some continental localities (e.g. Victoria Land). These form an important data resource to the climate conditions experienced by Antarctic terrestrial organisms.

Various types of logger are used. Sensors tend to be deployed at or near ground level and in and around particular types of vegetation, or other experimental sites, such as cloches. Loggers used include Grant, Delta-T, Campbell and Squirrels.

Victoria Land data for Kay Island and Edmonson Point in 1995 and 1996 was collected under the BIOTEX 1 experiment of the SCAR BIOTAS (Biological Investigations of Terrestrial Antarctic Systems) Programme. An overview of BIOTEX is available as a PDF file.
