1. Biodiversity loss has increased globally in recent years. The major threat to Antarctica’s unique terrestrial biodiversity is the establishment of non-native species. Nonetheless, while preventing the introduction of non-native […]
Snow thickness measurements over relatively smooth Arctic first-year sea ice, obtained near Cambridge Bay, Nunavut, Canada (2014, 2016 and 2017) and near Elson Lagoon, Alaska, USA (2003 and 2006), are […]
We present first observations of OH and (HO2 + RO2) carried out in Antarctica outside the summer season. Measurements were made over 23 days in spring at the coastal Antarctic […]
Myctophid fish are the most abundant and diverse mesopelagic fishes in the Southern Ocean. They are a conduit of energy between primary consumers and higher marine predators, and between the […]
Effective monitoring of changes in the geographic distribution of cryospheric vegetation requires high-resolution and accurate baseline maps. The rationale of the present study is to compare multiple feature extraction approaches […]
Within the context of global climate change and overfishing of fish stocks, there is some evidence that cephalopod populations are benefiting from this changing setting. These invertebrates show enhanced phenotypic […]
Power Line Harmonic Radiation and associated emissions observed at Siple [1, 2] are compared with line radiation activity observed at Halley, Antarctica [3]. We discuss the evidence for a Sunday […]
Four methods of investigating the thermal plasma density near the plasmapause have been intercompared for the period 1 to 15 July 1972. These methods are whistlers, the double floating probe […]
A launch, suspension and recovery technique for oceanic, in situ, 14C productivity measurements is described. Ship’s time for deployment of 125 ml incubation bottles at several depths down to 100 […]
