Meteor radar vertical wind observation biases and mathematical debiasing strategies including the 3DVAR+DIV algorithm
Read more of: Meteor radar vertical wind observation biases and mathematical debiasing strategies including the 3DVAR+DIV algorithmMeteor radars have become widely used instruments to study atmospheric dynamics, particularly in the 70 to 110 km altitude region. These systems have been proven to provide reliable and continuous […]

New mitogenomes in deep-water endemic Cocculinida and Neomphalida shed light on lineage-specific gene orders in major gastropod clades
Read more of: New mitogenomes in deep-water endemic Cocculinida and Neomphalida shed light on lineage-specific gene orders in major gastropod cladesGastropoda is the most speciose class in Mollusca, the second largest animal phylum, whose internal relationships remain largely unsettled, partly due to the insufficient data from key deep-water endemic lineages, […]

Observations of Modified Warm Deep Water beneath Ronne Ice Shelf, Antarctica, from an Autonomous Underwater Vehicle
Read more of: Observations of Modified Warm Deep Water beneath Ronne Ice Shelf, Antarctica, from an Autonomous Underwater VehicleFilchner-Ronne Ice Shelf (FRIS) is the world’s largest ice shelf by volume. It helps regulate Antarctica’s contribution to global sea level rise, and water mass transformations within the sub-ice-shelf cavity […]

Modeling the effects of drift shell splitting in two case studies of simultaneous observations of substorm-driven Pi1B and IPDP-type EMIC waves
Read more of: Modeling the effects of drift shell splitting in two case studies of simultaneous observations of substorm-driven Pi1B and IPDP-type EMIC wavesIntervals of Pulsations of Diminishing Periods (IPDPs) are a subtype of Electromagnetic Ion Cyclotron (EMIC) waves that can be triggered by substorm onset. Pi1B waves are Ultra Low Frequency (ULF) […]

Divergent foraging habitat preferences between summer-breeding and winter-breeding Procellaria petrels
Read more of: Divergent foraging habitat preferences between summer-breeding and winter-breeding Procellaria petrelsForaging niche specialisation is thought to occur when different members of speciose communities divide resources in either time or space. Here we compared habitat preferences of the congeneric Grey Petrel […]

Seabird and seal responses to the physical environment and to spatio-temporal variation in the distribution and abundance of Antarctic krill at South Georgia, with implications for local fisheries management
Read more of: Seabird and seal responses to the physical environment and to spatio-temporal variation in the distribution and abundance of Antarctic krill at South Georgia, with implications for local fisheries managementWe used 22 years of seasonally and spatially consistent monitoring data to explore marine predator–prey numerical response relationships. Specifically, we tested whether indices of offspring performance (e.g. offspring mass near the […]

Influence of marine vertebrates on organic matter, phosphorus and other chemical element levels in Antarctic soils
Read more of: Influence of marine vertebrates on organic matter, phosphorus and other chemical element levels in Antarctic soilsThe presence of marine vertebrates in dense reproductive colonies and other aggregations contributes to the input of organic matter and nutrients into the local environment and it is believed that […]

Temporal variability of quasilinear pitch-angle diffusion
Read more of: Temporal variability of quasilinear pitch-angle diffusionKinetic wave-particle interactions in Earth’s outer radiation belt energize and scatter high-energy electrons, playing an important role in the dynamic variation of the extent and intensity of the outer belt. […]

Animal survival strategies in Neoproterozoic ice worlds
Read more of: Animal survival strategies in Neoproterozoic ice worldsThe timing of the first appearance of animals is of crucial importance for understanding the evolution of life on Earth. Although the fossil record places the earliest metazoans at 572–602 Ma, […]

The Antarctic contribution to 21st-century sea-level rise predicted by the UK Earth System Model with an interactive ice sheet
Read more of: The Antarctic contribution to 21st-century sea-level rise predicted by the UK Earth System Model with an interactive ice sheetThe Antarctic Ice Sheet will play a crucial role in the evolution of global mean sea level as the climate warms. An interactively coupled climate and ice sheet model is […]

Geomagnetic disturbances that cause GICs: investigating their interhemispheric conjugacy and control by IMF orientation.
Read more of: Geomagnetic disturbances that cause GICs: investigating their interhemispheric conjugacy and control by IMF orientation.Nearly all studies of impulsive geomagnetic disturbances (GMDs, also known as magnetic perturbation events MPEs) that can produce dangerous geomagnetically induced currents (GICs) have used data from the northern hemisphere.
