DEEPER: The Drill for Extensive Exploration of Planetary Environments Using Robots
Read more of: DEEPER: The Drill for Extensive Exploration of Planetary Environments Using RobotsLanded missions which seek to explore ever-greater depths beneath planetary subsurfaces must manage the risks associated with this challenging task. When developing the most appropriate mission architecture, the designer must […]

Evidence of sub‐MeV EMIC‐driven trapped electron flux dropouts from GPS observations
Read more of: Evidence of sub‐MeV EMIC‐driven trapped electron flux dropouts from GPS observationsFor many years, it was believed that resonant interactions between electromagnetic ion cyclotron (EMIC) waves and radiation belt electrons were restricted to electron energies > 1 − 2 MeV. In […]

Geomagnetically induced currents during the 07-08 September 2017 disturbed period: a global perspective
Read more of: Geomagnetically induced currents during the 07-08 September 2017 disturbed period: a global perspectiveMeasurements from six longitudinally separated magnetic observatories, all located close to the 53⁰ mid-latitude contour, are analysed. We focus on the large geomagnetic 16 disturbance that occurred during 7 and […]

Fidelity of yellowfin tuna to seamount and island foraging grounds in the central South Atlantic Ocean
Read more of: Fidelity of yellowfin tuna to seamount and island foraging grounds in the central South Atlantic OceanThe yellowfin tuna (Thunnus albacares) is a widely distributed, migratory species that supports valuable commercial fisheries throughout their range. Management of migratory species requires knowledge of movement, mixing and key […]

Can Antarctica’s shallow zoobenthos ‘bounce back’ from iceberg scouring impacts driven by climate change?
Read more of: Can Antarctica’s shallow zoobenthos ‘bounce back’ from iceberg scouring impacts driven by climate change?All coastal systems experience disturbances and many across the planet are under unprecedented threat from an intensification of a variety of stressors. The West Antarctic Peninsula is a hotspot of […]

Pathways and modification of warm water flowing beneath Thwaites Ice Shelf, West Antarctica
Read more of: Pathways and modification of warm water flowing beneath Thwaites Ice Shelf, West AntarcticaThwaites Glacier is the most rapidly changing outlet of the West Antarctic Ice Sheet and adds large uncertainty to 21st century sea-level rise predictions. Here, we present the first direct […]

Brief Communication: New radar constraints support presence of ice older than 1.5 Ma at Little Dome C.
Read more of: Brief Communication: New radar constraints support presence of ice older than 1.5 Ma at Little Dome C.The area near Dome C, East Antarctica, is thought to be one of the most promising targets for recovering a continuous ice-core record spanning more than a million years. The […]

International response under the Antarctic Treaty System to the establishment of a non-native fly in Antarctica
Read more of: International response under the Antarctic Treaty System to the establishment of a non-native fly in AntarcticaAntarctica currently has few non-native species, compared to other regions of the planet, due to the continent’s isolation, extreme climatic conditions and the lack of habitat. However, human activity, particularly […]

Palmer Land and Graham Land volcanic groups (Antarctic Peninsula): Volcanology (Chapter 2.2a)
Read more of: Palmer Land and Graham Land volcanic groups (Antarctic Peninsula): Volcanology (Chapter 2.2a)The break-up of Gondwana during the Early–Middle Jurassic was associated with flood basalt volcanism in southern Africa and Antarctica (Karoo–Ferrar provinces), and formed one of the most extensive episodes of […]

Palmer Land and Graham Land volcanic groups (Antarctic Peninsula): Petrology (Chapter 2.2b)
Read more of: Palmer Land and Graham Land volcanic groups (Antarctic Peninsula): Petrology (Chapter 2.2b)Large-volume rhyolitic volcanism along the proto-Pacific margin of Gondwana consists of three major episodes of magmatism or ‘flare-ups’. The initial episode (V1) overlaps with the Karoo–Ferrar large igneous provinces at […]

Antarctic Peninsula and South Shetland Islands: Petrology (Chapter 3.1b)
Read more of: Antarctic Peninsula and South Shetland Islands: Petrology (Chapter 3.1b)The Antarctic Peninsula contains a record of continental-margin volcanism extending from Jurassic to Recent times. Subduction of the Pacific oceanic lithosphere beneath the continental margin developed after Late Jurassic volcanism […]
