Determining reliable proxies for the ionospheric signature of the open-closed field line boundary (OCB) is crucial for making accurate measurements of magnetic reconnection. This study compares the latitudes of spectral […]
The traditional view of Antarctica and the surrounding Southern Ocean as an isolated system is now being challenged by the recent discovery at the Antarctic Peninsula of adult spider crabs […]
The robustness of the aa geomagnetic index is of critical importance to the debate about the previously reported doubling of the solar coronal magnetic field in the last 100 years, […]
We have modeled the effects of the Sodankylä Ion Chemistry model (SIC) electron density profiles on VLF propagation across the southern polar region during the first few days of the […]
Dried monolayers of Chroococcidiopsis sp. 029, a desiccation-tolerant, endolithic cyanobacterium, were exposed to a simulated martian-surface UV and visible light flux, which may also approximate to the worst-case scenario for […]
When the interplanetary magnetic field (IMF) encounters the Earth’s magnetosphere, it is compressed and distorted. This distortion is known as draping, and plays an important role in the interaction between […]
Simple laminar flow models of the magnetosheath plasma lead to predictions of large-scale reconnection structures on the dayside magnetopause. There is observational evidence from the ionosphere that such structures exist. […]
A new species of cirrate octopod, Opisthoteuthis borealis sp. nov. is described from specimens caught at depths of 957–1321 m off the coast of Greenland. Opisthoteuthis borealis sp. nov. is […]
Body size trends across environmental gradients are widely reported but poorly understood. Here, we investigate contrasting relationships between size (body mass) and depth in the scavenging and predatory demersal ichthyofauna […]
The sea ice fraction in the interior of the pack, especially in winter, is important for climate studies and for validation of sea ice models. When ice concentration is high, […]
No Lepidoptera (butterflies and moths) are known to be residents of South Georgia. This paper presents new records of three lepidopterans on the island. Two, Agrotis ipsilon (Noctuidae) and Plutella […]
We describe a terrestrial faunal community including only Tardigrada and Rotifera, present on inland nunataks of Ellsworth Land, Antarctica (∼75°–77° S, 70°–73° W). The fauna is exceptional in its simplicity, […]
