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.
Ice shelves affect the stability of ice sheets by supporting the mass balance of ice upstream of the grounding line. Marine ice, formed from supercooled water freezing at the base of ice shelves, contributes to mass gain and affects ice dynamics.
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…
The Totten Glacier in East Antarctica, with an ice volume equivalent to >3.5?m of global sea-level rise, is grounded below sea level and, therefore, vulnerable to ocean forcing. Here…
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)…
Antarctic sea ice plays a crucial role in the global climate system and is highly sensitive to climate change and variability (Walsh 1983; Liu et al. 2002; Roach et al. 2020). Sea ice seasonally covers a vast area of the high-latitude Southern Ocean each year…
Antarctic sea ice plays a pivotal role in the global climate system. Forming a highly reflective, dynamic, and insulative blanket that varies seasonally in its areal coverage from ~3 × 106 km2 to ~19–20 × 106 km2, sea ice and its snow cover strongly modifies ocean…
Antarctic sea ice plays a pivotal role in the global climate system. Forming a highly-dynamic reflective and insulative blanket that varies seasonally from ~3 to ~20 × 106 km2, sea ice and its snow cover strongly modify ocean–atmosphere fluxes and interaction processes (Bourassa et al. 2013).
Carbon monoxide (CO) is a naturally occurring atmospheric trace gas, a regulated pollutant, and one of the main components determining the oxidative capacity of the atmosphere. Evaluating climate…
