The mesosphere is one of the most difficult parts of the atmosphere to sample; too high for balloon measurements and too low for in-situ satellites. Consequently there is a reliance…30 October, 2019 by Bianca Perren, Claire Allen
The sub-Antarctic island of South Georgia provides terrestrial and coastal marine records of climate variability, which are crucial for the understanding of the drivers of Holocene climate changes in the…29 October, 2019 by Mervyn Freeman
We use National Centers for Environmental Prediction/National Center for Atmospheric Research reanalysis data to show that Antarctic surface air temperature anomalies result from differences in the daily-mean duskward component, By,…29 October, 2019 by Richard Phillips
The Southern Ocean represents a continuous stretch of circumpolar marine habitat, but the potential physical and ecological drivers of evolutionary genetic differentiation across this vast ecosystem remain unclear. We tested…28 October, 2019 by John Turner
Recent major melting events in West Antarctica have raised concerns about a potential hydrofracturing and ice shelf instability. These events often share common forcings of surface melt-like anomalous radiative fluxes,…24 October, 2019 by Dominic Hodgson, Claus-Dieter Hillenbrand, James Smith, Michael Meredith, Stephen Roberts, William Dickens
The Antarctic Peninsula Ice Sheet is currently experiencing sustained and accelerating loss of ice. Determining when these changes were initiated and identifying the main drivers is hampered by the short…18 October, 2019 by Anna Belcher, Geraint Tarling, Simeon Hill
Antarctic krill (Euphausia superba) are swarming, oceanic crustaceans, up to two inches long, and best known as prey for whales and penguins – but they have another important role. With…17 October, 2019 by Jennifer Jackson, Peter Fretwell
We test the ability of Very High Resolution satellite (VHR) imagery to detect stranded whales using both manual and automated methods. We use the 2015 mass mortality event in the…17 October, 2019 by Mark Clilverd
VLF radio signals with travel times ~100 ms were observed continuously for up to ~11 hours at night on Rarotonga (Cook Islands, ~21°S) at 21.4 kHz from US Navy transmitter…16 October, 2019 by Jennifer Jackson
The recovery of whale populations from centuries of exploitation will have important management and ecological implications due to greater exposure to anthropogenic activities and increasing prey consumption. Here, a Bayesian…
