Ecosystem services of the Southern Ocean: trade-offs in decision-making.

Antarct Sci 2013 Oct 12;25(5):603-617. Epub 2013 Jun 12.

British Antarctic Survey , NERC , High Cross , Madingley Road , Cambridge CB3 0ET , UK.

Ecosystem services are the benefits that mankind obtains from natural ecosystems. Here we identify the key services provided by the Southern Ocean. These include provisioning of fishery products, nutrient cycling, climate regulation and the maintenance of biodiversity, with associated cultural and aesthetic benefits. Read More

Dissolved gases in perennially ice-covered lakes of the McMurdo Dry Valleys, Antarctica.

Antarct Sci 1998 Jun;10(2):124-33

SETI Institute, NASA Ames Research Center, Moffett Field, CA 94035, USA.

Measurements of dissolved N2, O2, Ar, CO2, and CH4 were made in perennially ice-covered Lake Hoare. Results confirm previous reports that O2 concentrations in the upper water column exceed atmospheric equilibrium and that N2 and Ar are supersaturated throughout the water column. The mean supersaturation of N2 was found to be 2. Read More

Soil temperatures and stability of ice-cemented ground in the McMurdo Dry Valleys, Antarctica.

Antarct Sci 1998 Mar;10(1):31-8

Space Science Division, NASA Ames Research Center, Moffett Field, CA 94035, USA.

Year-round temperature measurements at 1600 m elevation during 1994 in the Asgard Range Antarctica, indicate that the mean annual frost point of the ice-cemented ground, 25 cm below the surface, is -21.7 +/- 0.2 degrees C and the mean annual frost point of the atmosphere is -27. Read More
