Tropical daytime lower D-region dependence on sunspot number
Observed phases and amplitudes of VLF radio signals propagating on (near) tropical all-sea paths, both short, ∼300 km, and long, ∼10 Mm, are used to find daytime parameter changes for […]

Ammonium excretion by Antarctic krill Euphausia superba at South Georgia
Read more of: Ammonium excretion by Antarctic krill Euphausia superba at South GeorgiaExcretion by Antarctic krill Euphausia superba (hereafter ‘‘krill’’) is measured typically in small containers of filtered seawater for 12–24 h, which may cause a reduction of swimming, feeding, and metabolism. […]

Zonal distribution and seasonal vertical migration of copepod assemblages in the Scotia Sea
Read more of: Zonal distribution and seasonal vertical migration of copepod assemblages in the Scotia SeaLarge, biomass-dominant Southern Ocean copepod species have been much studied, but small and mesopelagic species also play major rôles in these ecosystems. However, little is known of some basic aspects […]

Burrowing in the Antarctic anemone, Halcampoides sp., from Signy Island, Antarctica
Read more of: Burrowing in the Antarctic anemone, Halcampoides sp., from Signy Island, AntarcticaAntarctic anemones of the genus Halcampoides inhabit low intertidal and shallow subtidal zones. They readily burrow into soft sediments following disturbance. The process of re-burying was recorded using time-lapse video […]

Identification of the low-altitude cusp by Super Dual Auroral Radar Network radars: A physical explanation for the empirically derived signature
Read more of: Identification of the low-altitude cusp by Super Dual Auroral Radar Network radars: A physical explanation for the empirically derived signatureThe Super Dual Auroral Radar Network (SuperDARN) radars are proving to be a very powerful experimental tool for exploring solar wind-magnetosphere-ionosphere interactions. They measure the autocorrelation function (ACF) of the […]

Patterns of Holocene relative sea level change in the North of Britain and Ireland
Read more of: Patterns of Holocene relative sea level change in the North of Britain and IrelandTemporal and spatial patterns of relative sea level (RSL) change in the North of Britain and Ireland during the Holocene are examined. Four episodes, each defined by marked changes in […]

Diversity trends of Bryophytes in continental Antarctica
Read more of: Diversity trends of Bryophytes in continental AntarcticaBryophytes exhibit a decline in species richness with latitude across the sub-Antarctic islands, Antarctic Peninsula and Antarctic continent, but not within the Antarctic continent itself. We analyzed diversity and biogeographic […]

Experimental evaluation of the effectiveness of weighting regimes in reducing seabird by-catch in the longline toothfish fishery around South Georgia
Read more of: Experimental evaluation of the effectiveness of weighting regimes in reducing seabird by-catch in the longline toothfish fishery around South GeorgiaA series of experiments was carried out in February 1999 at South Georgia (Subarea 48.3) to examine the effects of different weighting regimes on the incidental mortality of birds caught […]

A combined zircon SHRIMP and Sm-Nd isotope study of high-grade paragneisses from the Mid-German Crystalline Rise: evidence for northern Gondwanan and Grenvillian provenance
Read more of: A combined zircon SHRIMP and Sm-Nd isotope study of high-grade paragneisses from the Mid-German Crystalline Rise: evidence for northern Gondwanan and Grenvillian provenanceSHRIMP analyses of detrital zircon cores from high-grade metasediments from the Mid-German Crystalline Rise, which is situated between Eastern Avalonia in the NW and Saxo-Thuringia in the SE, yield mostly […]

Metamorphic evolution of garnet-epidote-biotite gneiss from the Moine Supergroup, Scotland, and geotectonic implications
Read more of: Metamorphic evolution of garnet-epidote-biotite gneiss from the Moine Supergroup, Scotland, and geotectonic implicationsMetapelitic gneisses from the Glenfinnan Group of the Moine Supergroup, Scotland, contain sparse large and numerous small garnets, associated with complex zoned epidote and plagioclase in a biotite matrix. The […]
