Recent benthic foraminifera communities offshore of Thwaites Glacier in the Amundsen Sea, Antarctica: implications for interpretations of fossil assemblages
Read more of: Recent benthic foraminifera communities offshore of Thwaites Glacier in the Amundsen Sea, Antarctica: implications for interpretations of fossil assemblagesBenthic foraminiferal assemblages are useful tools for paleoenvironmental studies but rely on the calibration of live populations to modern environmental conditions to allow interpretation of this proxy downcore. In regions […]

Long-term Variability and Tendencies of the Semidiurnal Tide in Mesosphere and Lower Thermosphere from Meteor Radar Observations Over Esrange (67.9°N, 21.1°E)
Read more of: Long-term Variability and Tendencies of the Semidiurnal Tide in Mesosphere and Lower Thermosphere from Meteor Radar Observations Over Esrange (67.9°N, 21.1°E)Long-term variability and tendencies in monthly mean semidiurnal tide (12-hr) in zonal (U12) and meridional (V12) winds are investigated in northern polar mesosphere and lower thermosphere (MLT; ∼80–100 km) using […]

An alternative representation of Synthetic Aperture Radar images as an aid to the interpretation of englacial observations
Read more of: An alternative representation of Synthetic Aperture Radar images as an aid to the interpretation of englacial observationsGround-penetrating radar reveals subsurface geometry and ice stratigraphy that contains information about past and present dynamics of the cryosphere. Synthetic Aperture Radar (SAR) is a processing technique based on averaging […]

Climate’s firm grip on glacier ablation in the Cordillera Darwin Icefield, Tierra del Fuego
Read more of: Climate’s firm grip on glacier ablation in the Cordillera Darwin Icefield, Tierra del FuegoThe Cordillera Darwin Icefield (CDI) in Tierra del Fuego is one of the largest temperate ice bodies in the Southern Hemisphere. We simulate the climatic energy and mass balance of […]

Subglacial landscape formation and sediment discharge: relating basal conditions to bedform dimensions and properties at Rutford Ice Stream, West Antarctica
Read more of: Subglacial landscape formation and sediment discharge: relating basal conditions to bedform dimensions and properties at Rutford Ice Stream, West AntarcticaBasal conditions that facilitate fast ice flow are still poorly understood and their parameterization in ice‐flow models results in high uncertainties in ice‐flow and consequent sea‐level rise projections. Direct observations […]

Developing a Southern Ocean Marine Ecosystem Model Ensemble to Assess Climate Risks and Uncertainties
Read more of: Developing a Southern Ocean Marine Ecosystem Model Ensemble to Assess Climate Risks and UncertaintiesClimate change could irreversibly modify Southern Ocean ecosystems. Marine ecosystem model (MEM) ensembles can assist policy making by projecting future changes and allowing the evaluation and assessment of alternative management […]

A polar oceans shipping information system
Read more of: A polar oceans shipping information systemGlobally, ships above a certain tonnage, as well as an increasing number of smaller vessels, rely on the AIS (Automatic Identification System) to safely navigate around other vessels, which are […]

Surface darkening by abundant and diverse algae on an Antarctic ice cap
Read more of: Surface darkening by abundant and diverse algae on an Antarctic ice capAlgal blooms play important roles in physical and biological processes on glacial surfaces. Despite this, their occurrence and impacts within an Antarctic context remain understudied. Here, we present evidence of […]

Ray tracing of very low frequency waves produced by active experiments or lightning events at low Earth orbit
Read more of: Ray tracing of very low frequency waves produced by active experiments or lightning events at low Earth orbitWe investigate the propagation in the plasmasphere of Very Low Frequency (VLF) electromagnetic waves, such as natural lightning-generated whistler waves and waves produced by active experiments. An active experiment is […]

Quantitative sub-ice and marine tracing of Antarctic sediment provenance (TASP v1.0)
Read more of: Quantitative sub-ice and marine tracing of Antarctic sediment provenance (TASP v1.0)Ice sheet models should be able to accurately simulate palaeo ice sheets to have confidence in their projections of future polar ice sheet mass loss and resulting global sea level […]
