Magnetically driven flow in a liquid-metal battery
We investigate the flow within a liquid-metal battery induced by an externally imposed magnetic field, B-0. An analytical model for laminar flow is proposed and this is found to be […]

Mismatches in scale between highly mobile marine megafauna and marine protected areas
Read more of: Mismatches in scale between highly mobile marine megafauna and marine protected areasMarine protected areas (MPAs), particularly large MPAs, are increasing in number and size around the globe in part to facilitate the conservation of marine megafauna under the assumption that large-scale […]

Variation in blood mercury concentrations in brown skuas (Stercorarius antarcticus) is related to trophic ecology but not breeding success or adult body condition
Read more of: Variation in blood mercury concentrations in brown skuas (Stercorarius antarcticus) is related to trophic ecology but not breeding success or adult body conditionMercury is a pervasive environmental contaminant that can negatively impact seabirds. Here, we measure total mercury (THg) concentrations in red blood cells (RBCs) from breeding brown skuas (Stercorarius antarcticus) (n […]

Genomic insights into the secondary aquatic transition of penguins
Read more of: Genomic insights into the secondary aquatic transition of penguinsPenguins lost the ability to fly more than 60 million years ago, subsequently evolving a hyper-specialized marine body plan. Within the framework of a genome-scale, fossil-inclusive phylogeny, we identify key […]

The Impact of Basal Roughness on Inland Thwaites Glacier Sliding
Read more of: The Impact of Basal Roughness on Inland Thwaites Glacier SlidingSwath radar technology enables three-dimensional mapping of modern glacier beds over large areas at resolutions that are higher than those typically used in ice-flow models. These data may enable new […]

Myctobase, a circumpolar database of mesopelagic fishes for new insights into deep pelagic prey fields
Read more of: Myctobase, a circumpolar database of mesopelagic fishes for new insights into deep pelagic prey fieldsThe global importance of mesopelagic fish is increasingly recognised, but they remain poorly studied. This is particularly true in the Southern Ocean, where mesopelagic fishes are both key predators and […]

Underwater visibility constrains the foraging behaviour of a diving pelagic seabird
Read more of: Underwater visibility constrains the foraging behaviour of a diving pelagic seabirdUnderstanding the sensory ecology of species is vital if we are to predict how they will function in a changing environment. Visual cues are fundamentally important for many predators when […]

Cpmoutational tools for metabolic modeling and gene duplication analysis
Read more of: Cpmoutational tools for metabolic modeling and gene duplication analysisThis thesis presents new computational methods to analyse both short and long-term effects of temperature increase on biological systems. First, we consider the problem of acclimation of an organism to […]

Shell thickness of Nucella lapillus in the North Sea increased over the last 130 years despite ocean acidification
Read more of: Shell thickness of Nucella lapillus in the North Sea increased over the last 130 years despite ocean acidificationOcean acidification and global climate change are predicted to negatively impact marine calcifiers, with species inhabiting the intertidal zone being especially vulnerable. Current predictions of organism responses to projected changes […]

Signatures of selection on mitonuclear integrated genes uncover hidden mitogenomic variation in fur seals
Read more of: Signatures of selection on mitonuclear integrated genes uncover hidden mitogenomic variation in fur sealsNuclear copies of mitochondrial genes (numts) are commonplace in vertebrate genomes and have been characterized in many species. However, relatively little attention has been paid to understanding their evolutionary origins […]

Early to middle Miocene ice sheet dynamics in the westernmost Ross Sea (Antarctica): Regional correlations
Read more of: Early to middle Miocene ice sheet dynamics in the westernmost Ross Sea (Antarctica): Regional correlationsThe present-day morpho-stratigraphy of the Ross Sea is the result of Cenozoic tectonic and cryospheric events, and constitutes a key record of Antarctica’s cryospheric evolution. An enduring problem in interpreting […]

Central tropical Pacific convection drives extreme high temperatures and surface melt on the Larsen C Ice Shelf, Antarctic Peninsula
Read more of: Central tropical Pacific convection drives extreme high temperatures and surface melt on the Larsen C Ice Shelf, Antarctic PeninsulaNorthern sections of the Larsen Ice Shelf, eastern Antarctic Peninsula (AP) have experienced dramatic break-up and collapse since the early 1990s due to strong summertime surface melt, linked to strengthened […]
