The formation of vertical edges on Antarctic moss peat banks
Moss peat banks, which can be up to 3 m deep, greater than 2500 m2 in area, and up to 5000 yr old, occur in the Antarctic. Radiocarbon dates show […]

Late Mesozoic sedimentation in the northern Antarctic Peninsula and its relationship to the southern Andes
Read more of: Late Mesozoic sedimentation in the northern Antarctic Peninsula and its relationship to the southern AndesTwo distinct phases of island-are evolution are recognized in late Mesozoic sedimentary rocks of the northern Antarctic Peninsula. During late Jurassic (Kimmeridgian-Tithonian) times, alternating radiolaria-rich mudstones and ash-fall tuffs were […]

Lacustrine deltas in a Mesozoic alluvial sequence from Camp Hill, Antarctica
Read more of: Lacustrine deltas in a Mesozoic alluvial sequence from Camp Hill, AntarcticaSedimentary rocks of late Mesozoic age exposed at Camp Hill, northern Antarctic Peninsula, are associated with calc‐alkaline volcanic rocks. They represent deposition on a fault‐controlled floodplain, with marginal alluvial fans, […]

Inter-annual isotopic niche segregation of wild humboldt penguins through years of different El Niño intensities
Read more of: Inter-annual isotopic niche segregation of wild humboldt penguins through years of different El Niño intensitiesThe Humboldt Current System presents high interannual variability, influenced by the El Niño Southern Oscillation (ENSO), whose implications in wildlife are not fully understood. We studied the isotopic niche of […]

Zooplankton and micronekton respond to climate fluctuations in the Amundsen Sea polynya, Antarctica
Read more of: Zooplankton and micronekton respond to climate fluctuations in the Amundsen Sea polynya, AntarcticaThe vertical migration of zooplankton and micronekton (hereafter ‘zooplankton’) has ramifications throughout the food web. Here, we present the first evidence that climate fluctuations affect the vertical migration of zooplankton […]

Diurnal variations in mean volume backscattering strength of an Antarctic krill (Euphausia superba) patch
Read more of: Diurnal variations in mean volume backscattering strength of an Antarctic krill (Euphausia superba) patchA series of acoustic transects and quantitative net hauls was made in a large patch of Antarctic krill (Euphausia superba) just north of South Georgia. The krill went through a […]

State of balance of the ice sheet in the Antarctic Peninsula
Read more of: State of balance of the ice sheet in the Antarctic PeninsulaData from ice rises on the east coast of the Antarctic Peninsula can be interpreted as showing that the ice is thinning at rates of up 0.5 m a−1. However, […]
