The significance of cephalopod beaks as a research tool: An update
Read more of: The significance of cephalopod beaks as a research tool: An updateThe use of cephalopod beaks in ecological and population dynamics studies has allowed major advances of our knowledge on the role of cephalopods in marine ecosystems in the last 60 years. […]

Late Eocene signals of oncoming Icehouse conditions and changing ocean circulation, Antarctica
Read more of: Late Eocene signals of oncoming Icehouse conditions and changing ocean circulation, AntarcticaThe end of the Eocene greenhouse world was the most dramatic phase in the long-term Cenozoic cooling trend. Here we use 75,000 km of multi/single channel seismic reflection data from […]

Using MEPED observations to infer plasma density and chorus intensity in the radiation belts
Read more of: Using MEPED observations to infer plasma density and chorus intensity in the radiation beltsEfforts to model and predict energetic electron fluxes in the radiation belts are highly sensitive to local wave-particle interactions. In this study, we use multi-point measurements of precipitating and trapped […]

Benthic dissolved silicon and iron cycling at glaciated Patagonian fjord heads
Read more of: Benthic dissolved silicon and iron cycling at glaciated Patagonian fjord headsGlacier meltwater supplies silicon (Si) and iron (Fe) sourced from weathered bedrock to downstream ecosystems. However, the extent to which these nutrients reach the ocean is regulated by the nature […]

Supraglacial debris thickness and supply rate in High-Mountain Asia
Read more of: Supraglacial debris thickness and supply rate in High-Mountain AsiaSupraglacial debris strongly modulates glacier melt rates and can be decisive for ice dynamics and mountain hydrology. It is ubiquitous in High-Mountain Asia, yet because its thickness and supply rate […]

The role of large-scale drivers in the Amundsen Sea Low variability and associated changes in water isotopes from the Roosevelt Island ice core, Antarctica
Read more of: The role of large-scale drivers in the Amundsen Sea Low variability and associated changes in water isotopes from the Roosevelt Island ice core, AntarcticaHere we examine the water stable-isotope data from the Roosevelt Island Climate Evolution (RICE) ice core. Roosevelt Island is an independent ice rise located at the northeastern margin of the […]

Cavity ringdown studies of the E–H transition in an inductively coupled oxygen plasma: comparison of spectroscopic measurements and modelling
Read more of: Cavity ringdown studies of the E–H transition in an inductively coupled oxygen plasma: comparison of spectroscopic measurements and modellingThe absolute number density of ground state oxygen atoms, O(3P), present in a 100 mTorr oxygen plasma has been determined as a function of operating power using cavity ringdown spectroscopy […]

Evidence of resource partitioning between fin and sei whales during the twentieth-century whaling period
Read more of: Evidence of resource partitioning between fin and sei whales during the twentieth-century whaling periodInvestigating resource partitioning of marine predators is essential for understanding coexistence of sympatric species and the functional role they play in marine ecosystems. Baleen whales are a key component of […]

Food falls in the deep northwestern Weddell Sea
Read more of: Food falls in the deep northwestern Weddell SeaWhen pelagic organisms die and fall onto the deep-sea floor they create food falls, parcels of organic enrichment that subsidize deep benthic scavenging communities. The diversity and quantities of food […]

Complete distribution of the genus Laevilitorina (Littorinimorpha: Littorinidae) in the Southern Hemisphere: remarks and natural history
Read more of: Complete distribution of the genus Laevilitorina (Littorinimorpha: Littorinidae) in the Southern Hemisphere: remarks and natural historyLittorinid snails are present in most coastal areas globally, playing a significant role in the ecology of intertidal communities. Laevilitorina is a marine gastropod genus distributed exclusively in the Southern […]

Microcystin production by oscillatorialean cyanobacteria isolated from cryopreserved Antarctic mats
Read more of: Microcystin production by oscillatorialean cyanobacteria isolated from cryopreserved Antarctic matsTwenty cyanobacterial strains of eight morphospecies isolated from deep-frozen (-15 °C) mat samples originally collected on Ross Island, in Victoria Land, and on the McMurdo Ice Shelf were screened for […]
