Evidence of marine ice-cliff instability in Pine Island Bay from iceberg-keel plough marks
Read more of: Evidence of marine ice-cliff instability in Pine Island Bay from iceberg-keel plough marksMarine ice-cliff instability (MICI) processes could accelerate future retreat of the Antarctic Ice Sheet if ice shelves that buttress grounding lines more than 800 metres below sea level are lost1, […]

Biological and physical characterization of the seabed surrounding Ascension Island from 100–1000 m
Read more of: Biological and physical characterization of the seabed surrounding Ascension Island from 100–1000 mRecent studies have improved our understanding of nearshore marine ecosystems surrounding Ascension Island (central Atlantic Ocean), but little is known about Ascension’s benthic environment beyond its shallow coastal waters. Here, […]

The role of Malcolm Clarke (1930–2013) in the Azores as a scientist and educationist
Read more of: The role of Malcolm Clarke (1930–2013) in the Azores as a scientist and educationistMalcolm Roy Clarke (1930–2013) was a British teuthologist who made an important contribution to marine science in the Azores archipelago (Portugal). Malcolm started doing research in the Azores from 1980s […]

High-resolution sub-ice-shelf seafloor records of twentieth century ungrounding and retreat of Pine Island Glacier, West Antarctica
Read more of: High-resolution sub-ice-shelf seafloor records of twentieth century ungrounding and retreat of Pine Island Glacier, West AntarcticaPine Island Glacier Ice Shelf (PIGIS) has been thinning rapidly over recent decades, resulting in a progressive drawdown of the inland ice and an upstream migration of the grounding line. […]

Occurrence characteristics of relativistic electron microbursts from SAMPEX observations
Read more of: Occurrence characteristics of relativistic electron microbursts from SAMPEX observationsWe study the occurrence of relativistic microbursts observed by the Solar Anomalous Magnetospheric Particle Explorer (SAMPEX) satellite. An algorithm is used to identify 193,694 relativistic microbursts in the > 1.05 […]

Solution of the Fokker-Planck equation with a logarithmic potential and mixed eigenvalue spectrum
Read more of: Solution of the Fokker-Planck equation with a logarithmic potential and mixed eigenvalue spectrumMotivated by a problem in climate dynamics, we investigate the solution of a Bessel-like process with a negative constant drift, described by a Fokker-Planck equation with a potential V(x) = […]

The fate of the non-native collembolon, Hypogastrura viatica, at the southern end of its introduced range in Antarctica
Read more of: The fate of the non-native collembolon, Hypogastrura viatica, at the southern end of its introduced range in AntarcticaInvasive species present a risk to Antarctic ecosystems by altering community structure and function. Reports of non-native invertebrates are increasing at Antarctic sites subject to tourism industry and national operator […]

How dynamic are ice-stream beds?
Read more of: How dynamic are ice-stream beds?Projections of sea-level rise contributions from West Antarctica’s dynamically thinning ice streams contain high uncertainty because some of the key processes involved are extremely challenging to observe. An especially poorly […]

A new bed elevation model for the Weddell Sea sector of the West Antarctic Ice Sheet
Read more of: A new bed elevation model for the Weddell Sea sector of the West Antarctic Ice SheetWe present a new bed elevation digital elevation model (DEM), with a 1 km spatial resolution, for the Weddell Sea sector of the West Antarctic Ice Sheet. The DEM has a […]

Ocean-forced ice-shelf thinning in a synchronously coupled ice-ocean model
Read more of: Ocean-forced ice-shelf thinning in a synchronously coupled ice-ocean modelThe first fully synchronous, coupled ice shelf-ocean model with a fixed grounding line and imposed upstream ice velocity has been developed using the MITgcm (Massachusetts Institute of Technology general circulation […]
