A major subglacial lake, Lake Snow Eagle (LSE), was identified in East Antarctica by airborne geophysical surveys. LSE, contained within a subglacial canyon, likely hosts a valuable sediment record of the geological and glaciological changes of interior East Antarctica.
Toward the poles, life on land is increasingly dominated by microorganisms, yet the evolutionary origin of polar microbiomes remains poorly understood. Here, we use metabarcoding of Arctic, sub-Antarctic…
The mid- to high-latitudes of the Southern Hemisphere are dominated by the westerly winds. These are important because changes in their strength determine precipitation and temperature regimes. However, little is known about their past strength, or spatial and temporal variability.
Data from a new regional airborne geophysical survey (ICECAP) has transformed our appreciation of the topography … and glaciology associated with the Aurora Subglacial Basin in East Antarctica. Using these data in conjunction … with numerical ice sheet modelling…
Knowledge of environmental variability and change during the … Medieval Climate Anomaly (MCA ; ~800 to 1300 - 1400 AD) in the Southern Hemisphere has been characterized by a La Nina-like mean climate state in the Pacific Basin…
Aerogeophysical data obtained by the ICECAP project yield new insights into the basal … topography and evidence of new subglacial lakes within the Aurora Subglacial Basin, East … Antarctica. The new bed elevation map allows us to consider the flow paths of subglacial water.
Green sulfur bacteria (GSB) (Chlorobiaceae) are primary producers that are important in global … carbon and sulfur cycling in natural environments. An almost complete genome sequence for a … single, dominant GSB species (‘C-Ace’)…
Species of the genus Pyramimonas (Prasinophyceae) are a common, widespread, but minor component of the Antarctic marine phytoplankton. They are … often associated with the seasonal sea-ice environment. Pyramimonas gelidicola … (McFadden, Moestrup & Wetherbee, 1982)…
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…
