2. Introduction: an Atlas of Submarine Glacial Landforms

   Glacial landforms and sediments exposed sub-aerially have been the subject of description, analysis and interpretation for more than a century (e.g. De Laski 1864; De Geer 1889). Indeed, such features […]

3. Atlas of submarine glacial landforms: Modern, Quaternary and Ancient

   New geophysical techniques (multibeam echo sounding and 3D seismics) have revolutionized high-resolution imaging of the modern seafloor and palaeo-shelf surfaces in Arctic and Antarctic waters, generating vast quantities of data […]

4. Eradication of the non-native Poa pratensis colony at Cierva Point, Antarctica: A case study of international cooperation and practical management in an area under multi-party governance

   The on-going introduction of non-native species to Antarctica due to expanding human activity presents an increasing threat to biodiversity. Under the Protocol on Environmental Protection to the Antarctic Treaty, all […]

5. Environmental hazard assessment of contaminated soils in Antarctica: Using a structured tier 1 approach to inform decision-making

   Generally, Antarctica is considered to be an untouched area of the planet; however, the region’s ecosystems have been subject to increased human pressure for at least the past half-century. This […]

6. Survey of whistler mode chorus intensity at Jupiter

   Whistler mode chorus emission is important in the acceleration of electrons and filling of the radiation belts at Jupiter. In this work chorus magnetic intensity levels (frequency-integrated spectral density, PB) […]

7. A model providing long-term data sets of energetic electron precipitation during geomagnetic storms

   The influence of solar variability on the polar atmosphere and climate due to energetic electron precipitation (EEP) has remained an open question largely due to lack of a long-term EEP […]

8. An Upper Jurassic methane-seep limestone from the Fossil Bluff Group forearc basin of Alexander Island, Antarctica

   An anomalous Upper Jurassic limestone bed, 3 m thick, is present within the volcaniclastic infill of a forearc basin, exposed on Alexander Island, Antarctica. The limestone, formally designated the Gateway […]

9. New trigonioid bivalves from the Albian (Early Cretaceous) of Alexander Island, Antarctic Peninsula: systematics, paleoecology, and austral Cretaceous paleobiogeography

   Newly discovered trigonioid bivalves are systematically described from the Late Albian of the Fossil Bluff Group of Alexander Island, Antarctic Peninsula. The fauna includes Nototrigonia (Nototrigonia) ponticula Skwarko, N. (Callitrigonia) […]

10. New trigonioid bivalves from the Early Jurasic to earliest Cretaceous of the Antarctic Peninsula region: systematics and austral paleobiogeography

    New discoveries of trigonioid bivalves are documented from three areas in the Antartic Peninsula: the Fossil Bluff Group of Alexander Island, the Latady Formation of the Orville Coast, and the […]

11. Geographic structure in the Southern Ocean circumpolar brittle star Ophionotus victoriae (Ophiuridae) revealed from mtDNA and single-nucleotide polymorphism data

    Marine systems have traditionally been thought of as “open” with few barriers to gene flow. In particular, many marine organisms in the Southern Ocean purportedly possess circumpolar distributions that have […]

12. Sensitivity of an apparently hurricane-like polar low to sea surface temperature

    Polar lows are intense, small-scale cyclones in the high latitudes. Typically, polar lows are initiated through baroclinic processes, but they sometimes evolve into a post-baroclinic mature stage where air-sea interaction […]
