Genetic defects in Antarctic dogs
Read more of: Genetic defects in Antarctic dogsThe occurrence of congenital entropion and true haemophilia in a closed population of working British Antarctic Survey sledge dogs is described. The difficulties of determining the patterns of inheritance are […]

The breeding biology of the black-bellied storm-petrel Fregetta tropica
Read more of: The breeding biology of the black-bellied storm-petrel Fregetta tropicaThe breeding cycie and habits of the Black‐bellied Storm‐petrel are described from observations made over three seasons at Signy Island, South Orkney Islands. The species is strictly nocturnal on land […]

Protein deimination and extracellular vesicle profiles in Antarctic seabirds
Read more of: Protein deimination and extracellular vesicle profiles in Antarctic seabirdsPelagic seabirds are amongst the most threatened of all avian groups. They face a range of immunological challenges which seem destined to increase due to environmental changes in their breeding […]

Global ocean heat content in the Last Interglacial
Read more of: Global ocean heat content in the Last InterglacialThe Last Interglacial (129–116 thousand years ago (ka)) represents one of the warmest climate intervals of the past 800,000 years and the most recent time when sea level was metres higher […]

Influence of shelf break processes on the transport of warm waters onto the eastern Amundsen Sea continental shelf
Read more of: Influence of shelf break processes on the transport of warm waters onto the eastern Amundsen Sea continental shelfThe heat transported onto the continental shelf by Circumpolar Deep Water (CDW) is the main driver of ice shelf basal melting in the Amundsen Sea. Here, we investigate the slope […]

The Gondwanan margin in West Antarctica: insights from Late Triassic magmatism of the Antarctic Peninsula
Read more of: The Gondwanan margin in West Antarctica: insights from Late Triassic magmatism of the Antarctic PeninsulaTriassic orthogneisses of the Antarctic Peninsula provide evidence for the Palaeozoic and Mesozoic geological evolution of southern Gondwana within Pangaea. These rocks are sporadically exposed in southeastern Graham Land and […]

Gaussian mixture modeling describes the geography of the surface ocean carbon budget.
Read more of: Gaussian mixture modeling describes the geography of the surface ocean carbon budget.Abstract—We use an unsupervised classification technique (i.e. Gaussian mixture modeling or GMM) to identify ocean regions with similar balances between processes that determine the surface budget of dissolved inorganic carbon. […]

Stratospheric ozone changes from explosive tropical volcanoes: Modeling and ice core constraints
Read more of: Stratospheric ozone changes from explosive tropical volcanoes: Modeling and ice core constraintsMajor tropical volcanic eruptions have emitted large quantities of stratospheric sulphate and are potential sources of stratospheric chlorine although this is less well constrained by observations. This study combines model […]

Food spectrum and trophic position of an Arctic cephalopod, Rossia palpebrosa (Sepiolida), inferred by stomach contents and stable isotope (δ13C and δ15N) analyses
Read more of: Food spectrum and trophic position of an Arctic cephalopod, Rossia palpebrosa (Sepiolida), inferred by stomach contents and stable isotope (δ13C and δ15N) analysesRossia palpebrosa (Sepiolida) is the most abundant nekto-benthic cephalopod in the Arctic; however, its feeding and trophic ecology are largely unknown. This work aims to assess the role of this […]
