Oceanographic conditions beneath Fimbul Ice Shelf, Antarctica [PDF]
, 2012 Antarctic ice shelves play a key role in the global climate system, acting as important sites for the cooling of shelf waters, thereby facilitating deep and bottom water formation.

Improved simulation of Antarctic sea ice due to the radiative effects of falling snow
Environmental Research Letters, 2017 Southern Ocean sea-ice cover exerts critical control on local albedo and Antarctic precipitation, but simulated Antarctic sea-ice concentration commonly disagrees with observations.

The long-term sea-level commitment from Antarctica [PDF]
The CryosphereThe evolution of the Antarctic Ice Sheet is of vital importance given the coastal and societal implications of ice loss, with a potential to raise sea level by up to 58 m if it melts entirely.

Oikos, EarlyView.Glaciers are receding at unprecedented rates worldwide, exposing large areas of barren sediment that are quickly colonized by microbes. Nutrient availability is a critical driver of early ecosystem succession, but in the High Arctic its role has remained uncertain.

Switch-off of a major enhanced ice flow unit in East Antarctica [PDF]
, 2006 The East Antarctic Ice Sheet (EAIS) is the largest reservoir of ice on the planet by an order of magnitude. Compared with the West Antarctic Ice Sheet (WAIS), it is traditionally considered to be relatively stable, with only minor adjustments to its ...

Permafrost and Periglacial Processes, EarlyView.ABSTRACT Permafrost in northern peatlands occurs within individual palsas or extensive peat plateaus and controls local carbon storage. These permafrost landforms are complex, and their internal structure remains poorly understood. We used quasi‐3D electrical resistivity tomography (ERT) measurements, supported by UAV‐LiDAR topography, frost probing ...

Permafrost and Periglacial Processes, EarlyView.ABSTRACT The McMurdo Dry Valleys, the largest ice‐free region in Antarctica, are home to a cold‐desert hydrologic system of glaciers, snowbanks, streams, and lakes. Freshwater is also stored as dead glacial ice, which is poorly constrained in terms of ion concentrations and interactions with both in situ and overlying sediments.

Coupled observation‐operator approximations in outer‐loop coupling data assimilation
Quarterly Journal of the Royal Meteorological Society, EarlyView.We present a methodology for coupled variational data assimilation that allows the effect of coupled observation operators whilst maintaining separate minimisations across model components. This allows us to constrain the atmosphere, ocean, and sea‐ice components of our coupled model directly from satellite radiances. We illustrate the system in action

Estimating the distribution of demand for Antarctic krill (Euphauisa superba) from land-based predators at South Georgia [PDF]
, 2007 South Georgia is renowned for the abundance of Antarctic krill (Euphausia superba) and a range of krill predators. Variability in krill availability at a range of scales, and the consequences of this for predator-prey interactions, mean that quantifying ...

Modelling sea-level observations to investigate the source and magnitude of major meltwater pulses during termination 1 [PDF]
, 2006 The research presented in this thesis utilises available near and far-field sea- level records to provide constraints on the major rapid sea-level rise events that occurred during the most recent period of deglaciation (Termination 1).The far-field ...
