The 1969 subglacial eruption on Deception Island (Antarctica): events and processes during an eruption beneath a thin glacier and implications for volcanic hazards
Read more of: The 1969 subglacial eruption on Deception Island (Antarctica): events and processes during an eruption beneath a thin glacier and implications for volcanic hazardsA short-lived eruption of basaltic andesite to andesite on Deception Island in 1969 occurred from a series of fissures underneath a glacier. The glacier was thin (c. 100 m) and […]

Copepod growth and development around South Georgia: relationships with temperature, food and krill
Read more of: Copepod growth and development around South Georgia: relationships with temperature, food and krillMeasurements of egg production rates (EPR) and growth of the early stages of 2 of the Southern Ocean biomass dominant copepods, Calanoides acutus and Rhincalanus gigas, were made over the […]

Summertime NOx measurements during the CHABLIS campaign: can source and sink estimates unravel observed diurnal cycles?
Read more of: Summertime NOx measurements during the CHABLIS campaign: can source and sink estimates unravel observed diurnal cycles?NOx measurements were conducted at the Halley Research Station, coastal Antarctica, during the austral summer period 1 January–10 February 2005. A clear NOx diurnal cycle was observed with minimum concentrations […]

Springtime transition in upper mesospheric temperature in the northern hemisphere
Read more of: Springtime transition in upper mesospheric temperature in the northern hemisphereAirglow emission observations by the wind imaging interferometer (WINDII) on the Upper Atmosphere Research Satellite and three optical ground-based stations previously revealed a “springtimetransition” in atomic oxygen. The transition is […]

Intrinsic gene expression during regeneration in arm explants of Amphiura filiformis
Read more of: Intrinsic gene expression during regeneration in arm explants of Amphiura filiformisThe extensive regeneration ability of ophiuroids, particularly in relation to arm re-growth following amputation, is becoming increasingly recognized as a useful model system for understanding cellular differentiation and regeneration in […]

Combined THEMIS and ground-based observations of a pair of substorm-associated electron precipitation events
Read more of: Combined THEMIS and ground-based observations of a pair of substorm-associated electron precipitation eventsUsing ground-based subionospheric radio wave propagation data from two very low frequency (VLF) receiver sites, riometer absorption data, and THEMIS satellite observations, we examine in detail energetic electron precipitation (EEP) […]

Dust and sea salt variability in central East Antarctica (Dome C) over the last 45 kyrs and its implications for southern high-latitude climate
Read more of: Dust and sea salt variability in central East Antarctica (Dome C) over the last 45 kyrs and its implications for southern high-latitude climateA detailed record of non-sea-salt calcium, a proxy for dust, and sea-salt sodium, a proxy for sea salt, covering the last 45 kyr is presented. It shows that in the […]

Nitrate in Greenland and Antarctic ice cores: a detailed description of post-depositional processes
Read more of: Nitrate in Greenland and Antarctic ice cores: a detailed description of post-depositional processesA compilation of nitrate (NO(3)(-)) data from Greenland has shown that recent NO(3)(-) concentrations reveal a temperature dependence similar to that seen in Antarctica. Except for sites with very low […]

Vertical resolution of oversampled limb-sounding measurements from satellites and aircraft
Read more of: Vertical resolution of oversampled limb-sounding measurements from satellites and aircraftMeasurements of trace gases by remote sensors which observe the atmospheric limb have a natural verticalresolution of 2–. With a typical field of view this becomes 3–. Oversampling, combined with […]
