    Aerial reconnaissance and photography are used in the Ross Sea sector of Antarctica to determine the breeding locations of Adélie penguins and to count the numbers of nests occupied during the early incubation period. From 1981 to present (two-year embargo), all islands and sea coasts between 158°E and 175°E have been searched, and 11 previously unreported breeding colonies discovered. The aim is to census Adélie (Pygoscelis adeliae) populations to provide basic data against which future population levels can be compared in order to monitor environmental change of the Antarctic Ocean ecosystem, both natural and man-induced.

  • There are nine soil climate stations located in the McMurdo Sound region of Antarctica that were established starting in 1999 through 2011. Four of the stations are in the Dry Valleys and four are located along the coast. The ninth station is located on Mt. Fleming near the polar plateau. Each climate station measures atmospheric parameters (air temperature, relative humidity, wind speed and direction, and solar radiation) and soil parameters (soil moisture and temperature) that extend from the active layer (seasonally thawed layer) into the permafrost. Recorded measurements are made on an hourly basis. At each climate station the soils have been sampled and characterized at the Kellogg Soil Survey Laboratory. There are two borehole stations at Bull Pass and Marble Point which measure ground temperature and are used to study permafrost temperatures and active-layer thermal regimes to a depth of 30m. Further station and borehole details including the instruments' specification, maintenance, and measured variables are described in each site's data "_description" folder. GET DATA:
