The Antarctic nematode Panagrolaimus sp. DAW1 is one of the only organisms known to survive extensive intracellular freezing throughout its tissues. Although the physiological mechanisms of this extreme adaptation are […]
A comprehensive set of autonomous, ice-ocean measurements were collected across the Canada Basin to study the summer evolution of the ice-ocean boundary layer (IOBL) and ocean mixed layer (OML). Evaluation […]
Previous work have shown that sea ice variability in the South Pacific is associated with extratropical atmospheric anomalies linked to the Southern Oscillation (SO). Over a 32 year period (1982–2013), our […]
Magnetosonic waves and electromagnetic ion cyclotron (EMIC) waves are important for electron acceleration and loss from the radiation belts. It is generally understood that these waves are generated by unstable […]
Nacella concinna (Strebel, 1908) held in seawater enriched with Sr, partially replaced Ca in their shells with Sr The bands laid down were clearly visible In back-scattered, scanning electron microscope […]
The effect of feeding on metabolism (specific dynamic action; SDA) was assessed in the articulate brachiopod Liothyrella uva (Broderip, 1833) at Signy Island, Antarctica. The response was low and on […]
A U-Pb zircon age 0f 285.7+/-1.5 Ma is presented for granodiorite from the Chanchoquin pluton of the Guanta Unit, Elqui Superunit of the Elqui-Limari Batholith. This is the first U-Pb […]
A comprehensive survey of data on ‘Polar Mesosphere Summer Echoes’, observed by the EISCAT VHF radar during 1988–1993, confirms that (1) these echoes are a summer phenomenon, with a season […]
The species composition, abundance, vertical distribution, biovolume and carbon content of gelatinous nekton in the Antarctic Polar Frontal Zone are described from a series of RMT25 hauls collected from a […]
Imported anthropogenic bacteria may survive the Antarctic winter and introduce new genes into local bacterial communities
