Products of subglacial volcanic eruptions under different ice thicknesses: two examples from Antarctica
Read more of: Products of subglacial volcanic eruptions under different ice thicknesses: two examples from AntarcticaLate Cenozoic, subglacially erupted volcanic sequences are scattered throughout the Antarctic Peninsula. Two of the best preserved examples, at Mount Pinafore (Alexander Island; c. 5.5–6 Ma) and Brown Bluff (Graham […]

On the dynamics of flow past a cylinder: Implications for CTD package motions and measurements
Read more of: On the dynamics of flow past a cylinder: Implications for CTD package motions and measurementsDuring the collection of ship-based observations, heaving of the vessel may lead to variation in the descent rate of a CTD package. This can result in the package being pulled […]

Global biogeographic patterns in bipolar moss species
Read more of: Global biogeographic patterns in bipolar moss speciesA bipolar disjunction is an extreme, yet common, biogeographic pattern in non-vascular plants, yet its underlying mechanisms (vicariance or long-distance dispersal), origin and timing remain poorly understood. Here, combining a […]
