Restricted regions of enhanced growth of Antarctic krill in the circumpolar Southern Ocean
Read more of: Restricted regions of enhanced growth of Antarctic krill in the circumpolar Southern OceanFood webs in high-latitude oceans are dominated by relatively few species. Future ocean and sea-ice changes affecting the distribution of such species will impact the structure and functioning of whole […]

Inter-specific niche partitioning and overlap in albatrosses and petrels: dietary divergence and the role of fishing discards
Read more of: Inter-specific niche partitioning and overlap in albatrosses and petrels: dietary divergence and the role of fishing discardsAlthough fisheries discards are recognized as a key food source for many seabirds, there have been few thorough assessments of their importance relative to natural prey, and of their influence […]

Energy transfer between energetic ring current H+and O+by electromagnetic ion cyclotron waves
Read more of: Energy transfer between energetic ring current H+and O+by electromagnetic ion cyclotron wavesElectromagnetic ion cyclotron (EMIC) waves in the frequency range below the helium gyrofrequency can be excited in the equatorial region of the outer magnetosphere by cyclotron resonant instability with anisotropic […]

Landau damping of magnetospherically reflected whistlers
Read more of: Landau damping of magnetospherically reflected whistlersUnducted VLF signals produced by lightning activity can form a population of magnetospherically reflected (MR) whistlers in the inner magnetosphere. It has been suggested recently that in the absence of […]

Taxonomic implications of morphological complexity within the testate amoeba genus Corythion from the Antarctic Peninsula
Read more of: Taxonomic implications of morphological complexity within the testate amoeba genus Corythion from the Antarctic PeninsulaPrecise and sufficiently detailed morphological taxonomy is vital in biology, for example in the accurate interpretation of ecological and palaeoecological datasets, especially in polar regions, where biodiversity is poor. Testate […]

Comparison of elevation change detection methods from ICESat altimetry over the Greenland Ice Sheet
Read more of: Comparison of elevation change detection methods from ICESat altimetry over the Greenland Ice SheetEstimation of the surface elevation change of the Greenland Ice Sheet (GrIS) is essential for understanding its response to recent and future climate change. Laser measurements from the NASA’s Ice, […]

Effects of low crude oil chronic exposure on the northern krill ( Meganyctiphanes norvegica )
Read more of: Effects of low crude oil chronic exposure on the northern krill ( Meganyctiphanes norvegica )Chronic oil pollution related to gas and oil drilling activities is increasing in the sea due to the rising offshore petroleum industry activity. Among marine organisms, zooplankton play a crucial […]
