Eocene microplankton from La Meseta Formation, northern Seymour Island
Read more of: Eocene microplankton from La Meseta Formation, northern Seymour IslandTwenty two samples collected from the Tertiary La Meseta Formation of Cape Wiman, Seymour Island, Antarctic Peninsula yielded abundant and moderately diverse assemblages of marine palynoflora, dominated by dinoflagellate cysts, […]

Observation of two preferred propagation paths for whistler mode VLF signals received at a non-conjugate location
Read more of: Observation of two preferred propagation paths for whistler mode VLF signals received at a non-conjugate locationWhistler mode signals from NLK (24.8 kHz) were received at Dunedin, New Zealand during 1989-90. The arrival bearing of the signals shows a bimodal distribution which is consistent with the […]

The effects of ionospheric horizontal electron density gradients on whistler mode signals
Read more of: The effects of ionospheric horizontal electron density gradients on whistler mode signalsWhistler mode group delays observed at Faraday, Antarctica (65° S, 64° W) and Dunedin, New Zealand (46° S, 171° E) show sudden increases of the order of hundreds of milliseconds […]

Proximate and elemental composition of gelatinous zooplankton from the Southern Ocean
Read more of: Proximate and elemental composition of gelatinous zooplankton from the Southern OceanWe have analysed the proximate composition and elemental (C,H,N) composition of eight gelatinous zooplankton from the Southern Ocean (two ctenophores, one anthomedusan, two siphonophorcs, one scyphozoan, one annelid and one […]

Egg size and composition in Ceratoserolis (Crustacea: Isopoda) from the Weddell Sea
Read more of: Egg size and composition in Ceratoserolis (Crustacea: Isopoda) from the Weddell SeaSamples of ovigerous female Ceratoserolis trilobitoides carrying newly spawned (stage A1) eggs in the marsupium were obtained from Borge Bay, Signy Island (South Orkney Islands), the continental shelf near Elephant […]

The Southern Ocean Benthic Fauna and Climate Change: A Historical Perspective [and Discussion]
Read more of: The Southern Ocean Benthic Fauna and Climate Change: A Historical Perspective [and Discussion]Environmental change is the norm and it is likely that, particularly on the geological timescale, the temperature regime experienced by marine organisms has never been stable. These temperature changes vary […]

Reproduction in the cold: Thorson revisited
Read more of: Reproduction in the cold: Thorson revisitedAlthough a tendency for high latitude marine invertebrates to avoid pelagic larval stages was first described in the 19th century, the most detailed early study was that of Thorson in […]

Cretaceous fossil wood and palynomorphs from Williams Point, Livingston Island, Antarctic Peninsula
Read more of: Cretaceous fossil wood and palynomorphs from Williams Point, Livingston Island, Antarctic PeninsulaTerrestrial palynofloras from two localities on Williams Point, Livingston, Island, contain angiosperm monocolpates and tricolpates and can be dated as Cenomanian-early Campanian. This fixes the age for a collection of […]

Relationship between heart rate and oxygen consumption during steady-state swimming in California sea lions
Read more of: Relationship between heart rate and oxygen consumption during steady-state swimming in California sea lionsHeart rate (fH) and rate of oxygen uptake (VO2) were measured in six subadult California sea lions Zalophus californianus while they were at rest and while they were swimming for […]
