The ICECAP project represents a return to the long-range, internationally collaborative … Antarctic aerogeophysics last seen in the 1970’s SPRI/NSF/TUD project. ICECAP is a joint … IPY collaboration between the University of Texas at Austin (funded by NSF), the University of … Edinburgh…
Sub-ice shelf bathymetry remains a poorly known but important boundary condition for … models of sub-ice shelf circulation and the distribution of basal melt and accretion. Surfacebased … seismic surveys are traditionally used to determine sub-ice shelf bathymetry…
Improved sampling technologies, international observing networks, and data synthesis efforts are providing an unprecedented view of the global patterns and decadal variability of surface-ocean partial pressure of carbon dioxide (pCO2) and air–sea CO2 flux.
The oxygen (O2) concentration in the surface ocean is influenced by biological and physical processes. With concurrent measurements of argon (Ar), which has similar solubility properties as oxygen…
Polar stratospheric gravity wave activity is studied using data from the Constellation … Observing System for Meteorology, Ionosphere and Climate (COSMIC) Global … Positioning System Radio Occultation (GPS-RO). Waves with vertical wavelengths of … 2 to 15 km are considered.
: Recent technological advances in the study and dating of both land and marine glacial geologic features combined with improvements in both glaciological and post-glacial isostatic rebound modelling have led to significant improvements in our knowledge and understanding of the Antarctic Ice Sheets…
In situ cosmogenic 10Be exposure dating, radiocarbon determinations, salt and sediment geochemistry, and rock weathering observations indicate that parts of Larsemann Hills, East Antarctica have been subaerially exposed throughout much of the last glacial cycle…
