Basal terraces on melting ice shelves
Ocean waters melt the margins of Antarctic and Greenland glaciers, and individual glaciers’ responses and the integrity of their ice shelves are expected to depend on the spatial distribution of […]

A paleolimnological reconstruction of Holocene climate change in southern Patagonia
Read more of: A paleolimnological reconstruction of Holocene climate change in southern PatagoniaTo fully understand the Holocene climatic variability in the sub-polar latitudes of the Southern Hemisphere and its driving mechanisms, like the Southern Hemisphere westerly winds, we undertook a multi-proxy analysis […]

Temporal and spatial structure of multi‐millennial temperature changes at high latitudes during the Last Interglacial
Read more of: Temporal and spatial structure of multi‐millennial temperature changes at high latitudes during the Last InterglacialThe Last Interglacial (LIG, 129–116 thousand of years BP, ka) represents a test bed for climate model feedbacks in warmer-than-present high latitude regions. However, mainly because aligning different palaeoclimatic archives […]

Inferring palaeo-accumulation records from ice-core data by an adjoint-based method: application to James Ross Island’s ice core
Read more of: Inferring palaeo-accumulation records from ice-core data by an adjoint-based method: application to James Ross Island’s ice coreIce cores contain a record of snow precipitation that includes information about past atmospheric circulation and mass imbalance in the polar regions. We present a novel adjoint method to reconstruct […]

Solar-wind-driven geopotential height anomalies originate in the Antarctic lower troposphere
Read more of: Solar-wind-driven geopotential height anomalies originate in the Antarctic lower troposphereWe use National Centers for Environmental Prediction/National Center for Atmospheric Research reanalysis data to estimate the altitude and time lag dependence of the correlation between the interplanetary magnetic field component, […]

Effect of plasma density on diffusion rates due to wave particle interactions with chorus and plasmaspheric hiss: extreme event analysis
Read more of: Effect of plasma density on diffusion rates due to wave particle interactions with chorus and plasmaspheric hiss: extreme event analysisWave particle interactions play an important role in controlling the dynamics of the radiation belts. The purpose of this study is to estimate how variations in the plasma density can […]

Energetic particle forcing of the Northern Hemisphere winter stratosphere: comparison to solar irradiance forcing
Read more of: Energetic particle forcing of the Northern Hemisphere winter stratosphere: comparison to solar irradiance forcingVariation in solar irradiance is considered an important factor in natural climate forcing. Variations in the solar UV in particular are now regarded as a major source of decadal variability […]

Commercial fishing vessel as research vessels in the Antarctic – requirements and solutions exemplified with a new vessel
Read more of: Commercial fishing vessel as research vessels in the Antarctic – requirements and solutions exemplified with a new vesselThe climate-induced changes presently seen in the ecosystems of the Antarctic region require a precautionary approach with respect to the human use of these ecosystems. In particular, resource harvesting requires […]

Variation of scavenger richness and abundance between sites of high and low iceberg scour frequency in Ryder Bay, west Antarctic Peninsula
Read more of: Variation of scavenger richness and abundance between sites of high and low iceberg scour frequency in Ryder Bay, west Antarctic PeninsulaPhysical disturbance, particularly from iceberg scour, is a major structuring force in polar benthic communities at shelf depths. Scouring kills and damages benthic organisms providing food for the abundant scavenging […]
