Basal sliding in Antarctic glaciers is often modeled using a friction law that relates basal shear stresses to the effective pressure. As few ice sheet models are dynamically coupled to subglacial hydrology models…
Dimethyl sulfide (DMS) and methanethiol (MeSH) are biologically co-produced marine volatile sulfur compounds, which play a critical role in climate-cooling aerosol formation. The spatio-temporal distributions of MeSH are poorly constrained, especially over the Southern Ocean.
Snow is a crucial and integral component of the sea ice system. It insulates the ice to retard the rate of thermodynamic ice thickening. At the same time, it contributes directly to sea-ice thickening through snow-ice formation…
A baseline for persistent organohalogen compound (POC) accumulation in the Antarctic … keystone species, Antarctic krill (Euphausia superba) has been established for a 50¡ã longitudinal … range of the eastern Antarctic sector. Samples of adult krill…
We present measurements and analysis of the isotopic composition (ä15Nbulk, ä15Ná, ä15Nâ, and ä18O) of nitrous oxide in 50 samples of tropospheric air collected at Cape Grim, Tasmania between 1978 and 2005 and in 11 samples of firn air from Law Dome, Antarctica…
Thorium-234 is increasingly used as a tracer of ocean particle flux, primarily as a means to estimate particulate organic carbon … export from the surface ocean. This requires determination of both the 234Th activity distribution (in order to calculate 234Th fluxes)…
