Potential subglacial lake locations and meltwater drainage pathways beneath the Antarctic and Greenland ice sheets
Read more of: Potential subglacial lake locations and meltwater drainage pathways beneath the Antarctic and Greenland ice sheetsWe use the Shreve hydraulic potential equation as a simplified approach to investigate potential subglacial lake locations and meltwater drainage pathways beneath the Antarctic and Greenland ice sheets. We validate […]

Acoustic discrimination of Southern Ocean zooplankton
Read more of: Acoustic discrimination of Southern Ocean zooplanktonAcoustic surveys in the vicinity of the sub-Antarctic island of South Georgia during a period of exceptionally calm weather revealed the existence of a number of horizontally extensive yet vertically […]

Variations in echosounder calibration with temperature, and some possible implications for acoustic surveys of krill biomass
Read more of: Variations in echosounder calibration with temperature, and some possible implications for acoustic surveys of krill biomassAccurate estimation of krill biomass by acoustic techniques is dependent on a number of factors of which one of the most fundamental is accurate echosounder calibration. The Simrad EK500 scientific […]

An assessment of the utility of an acoustic Doppler current profiler for biomass estimation
Read more of: An assessment of the utility of an acoustic Doppler current profiler for biomass estimationAcoustic Dopplerd current profilers (ADCPs) are being used increasingly to derive estimates of zooplankton and micronekton abundance. The absence of a practical means for users to perform ADCP calibration, however, […]

Dispersal of male and female Antarctic fur seals (Arctocephalus gazella)
Read more of: Dispersal of male and female Antarctic fur seals (Arctocephalus gazella)This study examined the foraging locations of adult male and female Antarctic fur seals (Arctocephalus gazella) in the Scotia Sea during the postbreeding period. Satellite transmitters were used to track […]

Circumstantial evidence for the presence of monk seals in the West Indies
Read more of: Circumstantial evidence for the presence of monk seals in the West IndiesBased on interviews with 93 fishermen in northern Haiti and Jamaica during 1997 an assessment was made of the likelihood that monk seals survive in this region of the West […]

Time and energy constraints in pinniped lactation
Read more of: Time and energy constraints in pinniped lactationPrevious reviews have recognized patterns of lactation in pinnipeds divided along phylogenetic lines. This study extended previous models of lactation in pinnipeds by explicitly taking into account all the energetic […]

A phylogenetic study of the squid family Onychoteuthidae (Cephalopoda: Oegopsida)
Read more of: A phylogenetic study of the squid family Onychoteuthidae (Cephalopoda: Oegopsida)The oegopsid squid family Onychoteuthidae presently comprises six genera (Moroteuthis, Onychoteuthis, Ancistroteuthis, Kondakovia, Onykia and Chaunoteuthis) but the status of some of these is still uncertain. An interdisciplinary study was […]

Cold tolerance of a New Zealand alpine cockroach, Celatoblatta quinquemaculata (Dictyoptera, Blattidae)
Read more of: Cold tolerance of a New Zealand alpine cockroach, Celatoblatta quinquemaculata (Dictyoptera, Blattidae)Ecophysiological features, including survival and recovery from freezing and determination of the freezable water content, are reported for a cold-adapted cockroach Celatoblatta quinquemaculata Johns 1966 (Dictyoptera, Blattidae) inhabiting alpine communities […]
