Deep water inflow slowed offshore expansion of the West Antarctic Ice Sheet at the Eocene-Oligocene transition
Read more of: Deep water inflow slowed offshore expansion of the West Antarctic Ice Sheet at the Eocene-Oligocene transitionThe stability of the West Antarctic Ice Sheet is threatened by the incursion of warm Circumpolar Deepwater which flows southwards via cross-shelf troughs towards the coast there melting ice shelves. […]

Persistent Ross Sea freshening from imbalance West Antarctic Ice Shelf melting
Read more of: Persistent Ross Sea freshening from imbalance West Antarctic Ice Shelf meltingA 63-year observational record in the southwest Ross Sea shows a continuing, near-linear salinity decrease of 0.170 and slight warming of 0.013°C through 2020. That freshening exceeded any increase in […]

Seasonal and interannual variability of feeding in Antarctic benthos
Read more of: Seasonal and interannual variability of feeding in Antarctic benthosThe seasonal and interannual variability of feeding in 15 species of benthic marine suspension feeder was studied over 8 yr at Ryder Bay, Antarctica. Feeding was strongly seasonal in bryozoans, gorgonians, […]

Under-ice light field analysis in the western Arctic Ocean during late summer
Read more of: Under-ice light field analysis in the western Arctic Ocean during late summerThe Arctic is no longer a region dominated by thick multi-year ice (MYI), but by thinner, more dynamic, first-year-ice (FYI). This shift towards a seasonal ice cover has consequences for […]

Rapid basal melting of the Greenland Ice Sheet from surface meltwater drainage
Read more of: Rapid basal melting of the Greenland Ice Sheet from surface meltwater drainageSubglacial hydrologic systems regulate ice sheet flow, causing acceleration or deceleration, depending on hydraulic efficiency and the rate at which surface meltwater is delivered to the bed. Because these systems […]

Sedimentary model for mixed depositional systems along the Pacific margin of the Antarctic Peninsula: decoding the interplay of deep-water processes
Read more of: Sedimentary model for mixed depositional systems along the Pacific margin of the Antarctic Peninsula: decoding the interplay of deep-water processesMixed (turbidite-contourite) depositional systems are formed by a complex interplay of deep-water processes. An evaluation of their morphological elements and their lateral and spatial distribution is crucial to better understand […]

British Antarctic Survey’s aerogeophysical data: releasing 25 years of airborne gravity, magnetic, and radar datasets over Antarctica
Read more of: British Antarctic Survey’s aerogeophysical data: releasing 25 years of airborne gravity, magnetic, and radar datasets over AntarcticaOver the past 50 years, the British Antarctic Survey (BAS) has been one of the major acquirers of aerogeophysical data over Antarctica, providing scientists with gravity, magnetic, and radar datasets […]

Aerial detection of beached marine plastic using a novel, hyperspectral short-wave infrared (SWIR) camera
Read more of: Aerial detection of beached marine plastic using a novel, hyperspectral short-wave infrared (SWIR) cameraPlastic pollution in the marine environment is a pervasive, global problem that threatens wildlife and human health. Routine monitoring is required to determine pollution hotspots, focus clean-up efforts, and assess […]

Ice core chronologies from the Antarctic Peninsula: The Palmer, Jurassic, and Rendezvous age-scales
Read more of: Ice core chronologies from the Antarctic Peninsula: The Palmer, Jurassic, and Rendezvous age-scalesIn this study, we present the age scales for three Antarctic Peninsula (AP) ice cores: Palmer, Rendezvous, and Jurassic. The three cores are all intermediate-depth cores, in the 133–141 m […]

Integrating immersion with GPS data improves behavioural classification for wandering albatrosses and shows scavenging behind fishing vessels mirrors natural foraging
Read more of: Integrating immersion with GPS data improves behavioural classification for wandering albatrosses and shows scavenging behind fishing vessels mirrors natural foragingAdvances in biologging techniques and the availability of high-resolution fisheries data have improved our ability to understand the interactions between seabirds and fisheries and to evaluate mortality risk due to […]
