The diversity, distribution and ecology of diatoms from Antarctic inland waters
Read more of: The diversity, distribution and ecology of diatoms from Antarctic inland watersDiatoms are abundant and diverse in many Antarctic freshwaters, with a general trend of decreasing diversity moving southwards. They form an important component of many benthic algal communities in streams […]

Arc evolution: a magnetic perspective from the Antarctic Peninsula
Read more of: Arc evolution: a magnetic perspective from the Antarctic PeninsulaThe Antarctic Peninsula is a Mesozoic–Cenozoic magmatic arc built on Palaeozoic and younger basement. It was formed by processes related to the subduction of Pacific ocean floor at its western […]

Quasi-biennial oscillation effects in the semidiurnal tide of the Antarctic lower thermosphere
Read more of: Quasi-biennial oscillation effects in the semidiurnal tide of the Antarctic lower thermosphereA continuous 37-year record of the geomagnetic field from Argentine Islands Geomagnetic Observatory at Faraday research station (65°S, 64°W), Antarctica, has been analysed to reveal a 27-month periodicity in the […]

Antarctic ice sheet melting in the southeast Pacific
Read more of: Antarctic ice sheet melting in the southeast PacificThe first oceanographic measurements across a deep channel beneath the calving front of Pine Island Glacier reveal a sub-ice circulation driven by basal melting of 10–12 m yr−1. A salt […]

Aeromagnetic data from the southern Weddell Sea embayment and adjacent areas: synthesis and interpretation
Read more of: Aeromagnetic data from the southern Weddell Sea embayment and adjacent areas: synthesis and interpretationA new regional aeromagnetic anomaly map covering the southern Weddell Sea and surrounding areas was produced by combining Russian and British magnetic anomaly data acquired between 1973 and 1989. The […]

Temperature and the biomass of flying midges (Diptera: Chironomidae) in the high Arctic
Read more of: Temperature and the biomass of flying midges (Diptera: Chironomidae) in the high ArcticWe tested the hypothesis that habitat temperature is the driving variable determining both the short-term and seasonal patterns of abundance (biomass) of Eying adult non-biting midges (Chironomidae) in the high […]

Can high Arctic soil microarthropods survive eleveated summer temperatures?
Read more of: Can high Arctic soil microarthropods survive eleveated summer temperatures?1. Tolerance of high summer temperatures was investigated in seven common species of oribatid mite (Acarina) and springtail (Collembola) found in soils associated with dominant vegetation types in West Spitsbergen, […]

Time-step limits for stable solutions of the ice-sheet equation
Read more of: Time-step limits for stable solutions of the ice-sheet equationVarious spatial discretizations for the ice sheet are compared for accuracy against analytical solutions in one and two dimensions. The computational efficiency of various iterated and non-iterated marching schemes is […]

Stability of ice rises and uncoupled marine ice sheets
Read more of: Stability of ice rises and uncoupled marine ice sheetsAn analysis of the linear stability of marine ice sheets uncoupled from associated ice shelves is presented. The principal feature is a zero eigenvalue associated with infinitesimal shifts along the […]

Stochastic perturbation of divide position
Read more of: Stochastic perturbation of divide positionPerturbation of divide position is considered by a linearization about the Vialov-Nye solution and also about related solutions with 0(1) relief. Relaxation times of one-sixteenth the fundamental thickness/accumulation-rate time-scale are […]
