The importance of Antarctic krill in biogeochemical cycles
Antarctic krill (Euphausia superba) are swarming, oceanic crustaceans, up to two inches long, and best known as prey for whales and penguins – but they have another important role. With […]

Spatial and temporal variations in basal melting at Nivlisen ice shelf, East Antarctica, derived from phase-sensitive radars
Read more of: Spatial and temporal variations in basal melting at Nivlisen ice shelf, East Antarctica, derived from phase-sensitive radarsThinning rates of ice shelves vary widely around Antarctica, and basal melting is a major component of ice shelf mass loss. In this study, we present records of basal melting […]

Using remote sensing to detect whale strandings in remote areas: the case of sei whales mass mortality in Chilean Patagonia
Read more of: Using remote sensing to detect whale strandings in remote areas: the case of sei whales mass mortality in Chilean PatagoniaWe test the ability of Very High Resolution satellite (VHR) imagery to detect stranded whales using both manual and automated methods. We use the 2015 mass mortality event in the […]

Particle‐in‐cell experiments examine electron diffusion by whistler‐mode waves: 1. Benchmarking with a cold plasma
Read more of: Particle‐in‐cell experiments examine electron diffusion by whistler‐mode waves: 1. Benchmarking with a cold plasmaUsing a particle‐in‐cell code, we study the diffusive response of electrons due to wave‐particle interactions with whistler‐mode waves. The relatively simple configuration of field‐aligned waves in a cold plasma is […]

Very low latitude whistler‐mode signals: Observations at three widely spaced latitudes
Read more of: Very low latitude whistler‐mode signals: Observations at three widely spaced latitudesVLF radio signals with travel times ~100 ms were observed continuously for up to ~11 hours at night on Rarotonga (Cook Islands, ~21°S) at 21.4 kHz from US Navy transmitter […]

Variability of quasilinear diffusion coefficients for plasmaspheric hiss
Read more of: Variability of quasilinear diffusion coefficients for plasmaspheric hissIn the Outer Radiation Belt, the acceleration and loss of high‐energy electrons is largely controlled by wave‐particle interactions. Quasilinear diffusion coefficients are an efficient way to capture the small‐scale physics […]

Seasonal variations in the total lipid content of Chorismus antarcticus (Pfeffer) (Crustacea: Decapoda) at South Georgia
Read more of: Seasonal variations in the total lipid content of Chorismus antarcticus (Pfeffer) (Crustacea: Decapoda) at South GeorgiaThe Antarctic benthic prawn Chorismus antarcticus (Pfeffer) was sampled regularly for a year and its total lipid content measured. Immature and transitional prawns had very variable lipid contents but similar […]

Lipid class and fatty acid composition of Chorismus antarcticus (Pfeffer) (Crustacea: Decapoda) at South Georgia
Read more of: Lipid class and fatty acid composition of Chorismus antarcticus (Pfeffer) (Crustacea: Decapoda) at South GeorgiaThe major lipids of the Antarctic benthic hippolytid prawn Chorismus antarcticus (Pfeffer) were phospholipid and triacylglycerol. There were small amounts of free sterol and alkyldiacylglycerol and traces of free fatty […]

Contamination of Peregrine falcons (Falco peregrinus) with fulmar stomach oil
Read more of: Contamination of Peregrine falcons (Falco peregrinus) with fulmar stomach oilSince 1971, four peregrine falcons, Falco peregrinus, coated with an oil‐like contamination, have been received for analysis at Monks Wood Experimental Station. All were from north or west Scotland. The […]
