Antarctic ice-free coastal environments, like the Vestfold Hills (East Antarctica), are shaped by a complex interplay of physical processes. This study synthesizes new data and existing research from the Vestfold Hills across marine, terrestrial and cryosphere science, meteorology, geomorphology…
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.
We present Bedmap3, the latest suite of gridded products describing surface elevation, ice-thickness and the seafloor and subglacial bed elevation of the Antarctic south of 60?°S. Bedmap3 incorporates and adds to all post-1950s datasets previously used for Bedmap2…
Microbial communities support the health and function of individual organisms, all the way up to global biomes. Given rapidly changing global ecosystems, there is an urgent need to be able to predict what changes to microbial community structure mean for the emergent community function.
One of the key components of this research has been the mapping of Antarctic bed topography and ice thickness parameters that are crucial for modelling ice flow and hence for predicting future ice loss and the ensuing sea level rise. Supported by the Scientific Committee on Antarctic Research (SCAR)…
Molecular tools are increasingly applied for assessing and monitoring biodiversity and informing conservation action. While recent developments in genetic and genomic methods provide greater sensitivity in analysis and the capacity to address new questions…
Atmospheric electric field … measurements from the Concordia station on the Antarctic Plateau are … compared with those from Vostok (560 km away) for the period of overlap … (2009–11) and to Carnegie (1915–29) and extended Vostok (2006–11) measurements.
Near-synchronized in situ, space-borne (A-Train) and ground-based … lidar observations are employed to evaluate the boundary-layer clouds (BLCs) over Tasmania and the adjacent Southern Ocean (SO) simulated by the … limited-area version of Australian Community Climate and Earth System … Simulator…
Reference IUGG-2058, Symposium M03 Weather and the Global Atmospheric Electric Circuit. Atmospheric electric field measurements from Concordia station on the Antarctic Plateau are compared with those from Vostok (560 km away) for the period of overlap (2009-2011) and to earlier Vostok (2006-2009)…
The Antarctic ice sheet holds a wealth of information on past climate variability, locked away in successive layers buried by further snowfall. In the coastal regions of Antarctica, snowfall rates can be high enough to hold layers of climate data on monthly, or better, time resolution.
The Dome Summit South ice core from Law Dome, East Antarctica is 1200 m long and reveals an unusually high accumulation rate for Late Holocene precipitation (640 kg m2/a), dating to 90,000 years before present (BP) at its base.
Measuring the parameters of the atmospheric circuit with hourly and daily time resolution … is difficult to achieve and demonstrate. However, a relationship between Vi, the ionosphere- … to-ground potential difference, and Ez, the near-ground-level vertical electric field…
Ice cores from coastal East Antarctica provide highly resolved records that capture seasonal variations … in a wide range of climate proxies.
Regular measurements of the atmospheric electric field made at Vostok Station (φ=78.451S; … ë=106.871E, elevation 3500 m) in Antarctica demonstrate that extremely intense electric fields … (1000–5000 V/m) can be observed during snow storms.
Pressure variations at 11 Antarctic and 7 Arctic sites show significant day-to-day correlations with a proxy for the … meteorological generators (thunderstorms and strongly electrified clouds) of the atmospheric circuit. The proxy is … derived from electric field measurements at Vostok (78.5ºS…
The atmospheric electric field Ez measured at the Antarctic Plateau station of Vostok made it possible to estimate … the role of the main generators in formation the global electric circuit. In the polar region during the periods with good … weather conditions the classical diurnal curve…
