Arctic East Siberia had a lower latitude in the Pleistocene

open access: yesAnais da Academia Brasileira de Ciências, 2007
Remains of mammoths in Arctic East Siberia, where there is not sufficient sunlight over the year for the growth of the plants on which these animals feed, indicate that the latitude of this region was lower before the end of the Pleistocene than now ...

Maximum strength and power as determinants of on-ice sprint performance in elite U16 to adult ice hockey players

open access: yesBiology of Sport, 2023
In ice hockey, speed strength is one of the major physical key performance indicators, which is significantly influenced by maximum strength. The objective of this study was to evaluate the age‑dependent relationship of off-ice maximum strength and ...

Mitogenomics of the Extinct Cave Lion, Panthera spelaea (Goldfuss, 1810), Resolve its Position within the Panthera Cats

open access: yesOpen Quaternary, 2016
The extinct cave lion ('Panthera spelaea') was an apex predator of the Pleistocene, and one of the largest felid species ever to exist. We report the first mitochondrial genome sequences for this species, derived from two Beringian specimens, one of ...

MATHEMATICAL MODELING OF ICE FLOW IN QUEEN MAUD LAND, ANTARCTICA, AND ITS APPLICATION TO THE LATE QUATERNARY CLIMATIC PALEORECONSTRUCTION

open access: yesЛëд и снег, 2015
One of the main sources of our knowledge about past air temperature variations is the isotopic composition of the ice cores obtained during deep drilling of the ice sheets. During 2001–2006 deep drilling was carried out at Kohnen station in Dronning Maud

A new tracking algorithm for sea ice age distribution estimation [PDF]

open access: yesThe Cryosphere, 2018
A new algorithm for estimating sea ice age (SIA) distribution based on the Eulerian advection scheme is presented. The advection scheme accounts for the observed divergence or convergence and freezing or melting of sea ice and predicts consequent ...

The evolution of the Fram Strait sea ice volume export decomposed by age: estimating with parameter-optimized sea ice-ocean model outputs

open access: yesEnvironmental Research Letters, 2023
Sea ice export through the Fram Strait is crucial in the dynamic evolution of Arctic sea ice and can further modulate Arctic sea ice mass balance as well as the ocean thermohaline circulation.

Mapping age and basal conditions of ice in the Dome Fuji region, Antarctica, by combining radar internal layer stratigraphy and flow modeling [PDF]

open access: yesThe Cryosphere, 2023
The Dome Fuji (DF) region in Antarctica is a potential site for an ice core with a record of over 1 Myr. Here, we combine large-scale internal airborne radar stratigraphy with a 1-D model to estimate the age of basal ice in the DF region.

The first luminescence dating of Tibetan glacier basal sediment [PDF]

open access: yesThe Cryosphere, 2018
Dating ice cores drilled in the high mountain glaciers is difficult because seasonal variations cannot be traced at depth due to rapid thinning of the ice layers.
