Pteropods in Southern Ocean ecosystems
To date, little research has been carried out on pelagic gastropod molluscs (pteropods) in Southern Ocean ecosystems. However, recent predictions are that, due to acidification resulting from a business as […]

Gyro-resonant electron acceleration at Jupiter
Read more of: Gyro-resonant electron acceleration at JupiterAccording to existing theory, electrons are accelerated up to ultra-relativistic energies(1) inside Jupiter’s magnetic field by betatron and Fermi processes as a result of radial diffusion towards the planet and […]

Spring mortality of the cyclopoid copepod Oithona similis in polar waters
Read more of: Spring mortality of the cyclopoid copepod Oithona similis in polar watersThe cyclopoid copepod Oithona similis is highly abundant and ubiquitous in the marine epipelagic environment, yet rates of mortality in this species have rarely been quantified; indeed we are lacking […]

Volcanic time-markers for Marine Isotopic Stages 6 and 5 in Southern Ocean sediments and Antarctic ice cores: implications for tephra correlations between palaeoclimatic records
Read more of: Volcanic time-markers for Marine Isotopic Stages 6 and 5 in Southern Ocean sediments and Antarctic ice cores: implications for tephra correlations between palaeoclimatic recordsThree megascopic and disseminated tephra layers (which we refer to as layers A, B, and C) occur in late Quaternary glaciomarine sediments deposited on the West Antarctic continental margin. The […]

The present and past bottom-current flow regime around the sediment drifts on the continental rise west of the Antarctic Peninsula
Read more of: The present and past bottom-current flow regime around the sediment drifts on the continental rise west of the Antarctic PeninsulaThroughout the last decade large sediment drifts located on the upper continental rise west of the Antarctic Peninsula were the target of oceanographic measurements, bathymetric mapping, seismic investigations. shallow sediment […]

A new method to determine the reproductive condition in female tubeworms tested in Seepiophila jonesi (Polychaeta: Siboglinidae: Vestimentifera)
Read more of: A new method to determine the reproductive condition in female tubeworms tested in Seepiophila jonesi (Polychaeta: Siboglinidae: Vestimentifera)Vestimentiferan tubeworms are significant members of deep-sea chemosynthetically-driven communities, including hydrothermal vents and cold seeps. The reproductive condition in this taxon is rarely studied because of sampling constraints inherent to […]

Quality assessment of water cycle parameters in REMO by radar-lidar synergy
Read more of: Quality assessment of water cycle parameters in REMO by radar-lidar synergyA comparison study of water cycle parameters derived from ground-based remote-sensing instruments and from the regional model REMO is presented. Observational data sets were collected during three measuring campaigns in […]

Spatial demography of Calanus finmarchicus in the Irminger Sea
Read more of: Spatial demography of Calanus finmarchicus in the Irminger SeaContinuous Plankton Recorder data suggest that the Irminger Sea supports a major proportion of the surface-living population of the copepod Calanus finmarchicus in the northern North Atlantic, but there have […]

Energetic outer radiation belt electron precipitation during recurrent solar activity
Read more of: Energetic outer radiation belt electron precipitation during recurrent solar activityTransmissions from three U.S. VLF (very low frequency) transmitters were received at Churchill, Canada, during an event study in May to November, 2007. This period spans four cycles of recurrent […]

Offshore spatial segregation in giant petrels Macronectes spp.: differences between species, sexes and seasons
Read more of: Offshore spatial segregation in giant petrels Macronectes spp.: differences between species, sexes and seasons1. Investigations were made to determine whether the two giant petrel species segregate by gender and species in relation to the stage of the annual cycle. The individual foraging behaviour […]
