1. Solar-wind-driven geopotential height anomalies originate in the Antarctic lower troposphere

   We 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, […]

2. Effect of plasma density on diffusion rates due to wave particle interactions with chorus and plasmaspheric hiss: extreme event analysis

   Wave 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 […]

3. Energetic particle forcing of the Northern Hemisphere winter stratosphere: comparison to solar irradiance forcing

   Variation 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 […]

4. Commercial fishing vessel as research vessels in the Antarctic – requirements and solutions exemplified with a new vessel

   The 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 […]

5. Variation of scavenger richness and abundance between sites of high and low iceberg scour frequency in Ryder Bay, west Antarctic Peninsula

   Physical 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 […]

7. The role of the Sun in long-term change in the F2 peak ionosphere: new insights from EEMD and numerical modelling

   We applied Ensemble Empirical Mode Decomposition (EEMD) for the first time to ionosonde data to study trends in the critical frequency of the F2 peak, foF2, and its height, hmF2, […]

8. Boundary condition of grounding lines prior to collapse, Larsen-B Ice Shelf, Antarctica

   Grounding zones, where ice sheets transition between resting on bedrock to full floatation, help regulate ice flow. Exposure of the sea floor by the 2002 Larsen-B Ice Shelf collapse allowed […]

9. Greenland deglaciation puzzles

   About 23,000 years ago, the southern margins of the great Northern Hemisphere ice sheets across Europe and North America began to melt. The melt rate accelerated ∼20,000 years ago, and […]

10. The ‘footloose’ mechanism: iceberg decay from hydrostatic stresses

    We study a mechanism of iceberg breakup that may act together with the recognized melt and wave-induced decay processes. Our proposal is based on observations from a recent field experiment […]

11. Phase-sensitive FMCW radar system for high-precision Antarctic ice shelf profile monitoring

    Ice shelves fringe much of the Antarctic continent, and, despite being up to 2 km thick, are vulnerable to climate change. Owing to their role in helping to control the […]

12. A new bathymetric compilation for the South Orkney Islands, Antarctic Peninsula (49°-39°W to 64°-59°S): insights into the glacial development of the continental shelf

    We present a new, high resolution (300 m) bathymetric grid of the continental shelf surrounding the South Orkney Islands, northeast of the Antarctic Peninsula. The new grid, derived from a […]
