We present a new time‐slice reconstruction of the Eurasian ice sheets
(British–Irish, Svalbard–Barents–Kara Seas and Scandinavian) documenting the
spatial evolution of these interconnected ice sheets every 1000 years from 25 to
10 ka, and at four selected time periods back to 40 ka. The time‐slice maps of
ice‐sheet extent are based on a new Geographical Information System (GIS)
database, where we ... hiện toàn bộ
Dating glacial and associated sediments is essential to provide a temporal
framework for accurate reconstructions of past climatic conditions and for
helping to determine the nature and magnitude of glaciation for landscape
evolution studies. There are few widely applicable, accurate and precise methods
available to date Quaternary landforms and sediments, despite the numerous
numerical dating met... hiện toàn bộ

High‐resolution bathymetric mapping of the fjords and continental shelf around
the Svalbard archipelago shows an extensive pattern of large‐ and medium‐scale
submarine landforms formed by differences in ice‐flow regimes. Mega‐scale
glacial lineations, lateral moraines, transverse ridges and glaciotectonic
features are superimposed on the large‐scale fjord, shelf and cross‐shelf trough
morphology o... hiện toàn bộ

The ahermatypic coral Lophelia pertusa which produces aragonitic skeletons is
widely distributed along the Norwegian coast. Specimens from a number of
localities have been analyzed for oxygen and stable carbon isotope composition
and 14C age. Stable isotope ratios of recent corals provide information on
growth rate and seasonality of oceanographic conditions. Lophelia can be useful
in paleoenviron... hiện toàn bộ
A revised lithostratigraphy of Skåne, South Sweden, constitutes the basis of an
alternative Weichselian glaciation model for southern Scandinavia, progressively
anchored to the stratigraphy. Skåne was not glaciated during the Weichselian
until 21,000 B.P. The concepts, outlet surge and marginal dome (the main tools
of the model) are defined. The palaeogeography of the Baltic and Kattegatt
basins d... hiện toàn bộ
This paper presents evidence on the timing and pattern of the Late Weichselian
deglaciation in SW Scandinavia, particularly in the Öresund–Kattegat region
before the Allerød interstadial. New radiocarbon ages and evaluated older dates
demonstrate that active glacier ice had left eastern Denmark, southern Halland
and western Skåne before 14,000 BP. The deglaciation in the Öresund region took
place ... hiện toàn bộ
The extent of a large mountain icefield that existed in the western Grampians
during the Loch Lomond stade has been mapped. The main types of evidence used in
establishing the limits comprise moraines, thick drift, fluvioglacial landforms,
erratics, ice‐smoothed bedrock, striae, friction cracks and relict periglacial
forms. Trimlines on 198 spurs, and various forms of glacial and periglacial
evide... hiện toàn bộ
