Spotlight on the invasion of a carabid beetle on an oceanic island over a 105-year period island
Read more of: Spotlight on the invasion of a carabid beetle on an oceanic island over a 105-year period islandThe flightless beetle Merizodus soledadinus, native to the Falkland Islands and southern South America, was introduced to the sub-Antarctic Kerguelen Islands in the early Twentieth Century. Using available literature data, […]

Long-term increase in Antarctic Ice Sheet vulnerability driven by bed topography evolution
Read more of: Long-term increase in Antarctic Ice Sheet vulnerability driven by bed topography evolutionIce sheet behavior is strongly influenced by the bed topography. However, the effect of the progressive temporal evolution of Antarctica’s subglacial landscape on the sensitivity of the Antarctic Ice Sheet […]

Terrain-aided navigation for long-range AUVs in dynamic under-mapped environments
Read more of: Terrain-aided navigation for long-range AUVs in dynamic under-mapped environmentsDeploying long‐range autonomous underwater vehicles (AUVs) mid‐water column in the deep ocean is one of the most challenging applications for these submersibles. Without external support and speed over the ground […]

Tidal modulation of buoyant flow and basal melt beneath Petermann Gletscher Ice Shelf, Greenland.
Read more of: Tidal modulation of buoyant flow and basal melt beneath Petermann Gletscher Ice Shelf, Greenland.A set of collocated, in situ oceanographic and glaciological measurements from Petermann Gletscher Ice Shelf, Greenland, provides insights into the dynamics of under‐ice flow driving basal melting. At a site […]

Supercooled Southern Ocean waters
Read more of: Supercooled Southern Ocean watersIn cold polar waters, temperatures sometimes drop below the freezing point, a process referred to as supercooling. However, observational challenges in polar regions limit our understanding of the spatial and […]

Unveiling Powell Basin’s tectonic domains and understanding its abnormal magnetic anomaly signature. Is heat the key?
Read more of: Unveiling Powell Basin’s tectonic domains and understanding its abnormal magnetic anomaly signature. Is heat the key?Rifting of continental lithosphere leading to oceanic basins is a complex process conditioned by different factors such as the rheology and thermal structure of the underlying lithosphere, as well as […]
