Overview of the Lost Meteorites of Antarctica field campaigns Open
The Lost Meteorites of Antarctica project was the first UK‐led Antarctic meteorite recovery expedition. The project has successfully confirmed two new high‐density meteorite stranding zones in the Hutichison Icefield and Outer Recovery Ice…

Loss of research and operational equipment in Antarctica: Balancing scientific advances with environmental impact Open
Antarctica has been subject to widespread, long-term and on-going human activity since the establishment of permanent research stations became common in the 1950s. Equipment may become intentionally or inadvertently lost in Antarctic marin…

Internal tsunamigenesis and ocean mixing driven by glacier calving in Antarctica Open
Ocean mixing around Antarctica exerts key influences on glacier dynamics and ice shelf retreats, sea ice, and marine productivity, thus affecting global sea level and climate. The conventional paradigm is that this is dominated by winds, t…

Carbon and Lipid Contents of the Copepod Calanus finmarchicus Entering Diapause in the Fram Strait and Their Contribution to the Boreal and Arctic Lipid Pump Open
The boreal copepod Calanus finmarchicus sequesters substantial amounts of carbon (C) in the deep layers of the North Atlantic Ocean through their contribution to the “lipid pump.” This pump is driven by these zooplankton descending from th…

Internal tsunamigenesis and mixing driven by glacier calving in Antarctica Open
<p>Ocean mixing around Antarctica is a key process that influences the vertical distributions of heat and nutrients, affecting glacier and ice shelf retreats, sea ice formation and marine productivity, with implications for regional …

Physical, biogeochemical and ecological impacts of giant icebergs: a multidisciplinary study of iceberg A68 near South Georgia, Southern Ocean   Open
<p>Giant icebergs can greatly impact the mass, freshwater and nutrient budgets of the ocean. They can deposit large amounts of freshwater at great distances from their origins, impacting upper-ocean stratification and mixing, and the…

Observing the Disintegration of the A68A Iceberg from Space Open
<p>Icebergs impact the physical and biological properties of the ocean along their drift trajectory by releasing cold fresh meltwater and nutrients. This facilitates sea ice formation, fosters biological production and influences the…

Benthic Biodiversity, Carbon Storage and the Potential for Increasing Negative Feedbacks on Climate Change in Shallow Waters of the Antarctic Peninsula Open
The importance of cold-water blue carbon as biological carbon pumps that sequester carbon into ocean sediments is now being realised. Most polar blue carbon research to date has focussed on deep water, yet the highest productivity is in th…

Observing the disintegration of the A68A iceberg from space Open
Icebergs impact the physical and biological properties of the ocean where they drift, depending on the degree of melting. We use satellite imagery and altimetry to quantify the area, thickness, and volume change of the massive A68A iceberg…

Evolutionary constraints on physiology confound range shift predictions of two nacellid limpets Open
Physiological comparisons are fundamental to quantitative assessments of the capacity of species to persist within their current distribution and to predict their rates of redistribution in response to climate change. Yet, the degree to wh…

Finding Antarctica’s Pole of Inaccessibility Open
Antarctica’s Pole of Inaccessibility (Southern Pole of Inaccessibility (SPI)) is the point on the Antarctic continent farthest from its edge. Existing literature exhibits disagreement over its location. Using two revisions of the Scientifi…

A comparison of baleen whale density estimates derived from overlapping satellite imagery and a shipborne survey Open
As whales recover from commercial exploitation, they are increasing in abundance in habitats that they have been absent from for decades. However, studying the recovery and habitat use patterns of whales, particularly in remote and inacces…

The spatial flux of Earth’s meteorite falls found via Antarctic data Open
Contemporary calculations for the flux of extraterrestrial material falling to the Earth’s surface (each event referred to as a “fall”) rely upon either short-duration fireball monitoring networks or spatially limited ground-based meteorit…

Whales from space: Four mysticete species described using new VHR satellite imagery Open
Large‐bodied animals such as baleen whales can now be detected with very high resolution (VHR) satellite imagery, allowing for scientific studies of whales in remote and inaccessible areas where traditional survey methods are limited or im…

KRILLBASE: a circumpolar database of Antarctic krill and salp numerical densities, 1926–2016 Open
Antarctic krill (Euphausia superba) and salps are major macroplankton contributors to Southern Ocean food webs and krill are also fished commercially. Managing this fishery sustainably, against a backdrop of rapid regional climate change, …
