Astronomie ; HERSCHEL (W.) ; Histoire de la géographie ; Histoire des sciences ; Sciences humaines ; Siècle 18
Comment la théorie mathématique de la musique a conduit Herschel à l'optique et à la confection de ses premiers télescopes. Il a fait plusieurs découvertes importantes : la planète Uranus, et deux de ses satellites, deux satellittes de Saturne, etc
Physical and chemical characteristics of the active layer and permafrost, Herschel Island, western Arctic Coast, Canada
The purposes of this paper are to discuss the geochemistry of the active layer and near-surface permafrost in cryosolic soils on northeastern Herschel Island, Yukon Territory, and to determine the effect of permafrost degradation on soil and surface
Origin and characteristics of massive ground ice on Herschel Island (western Canadian Arctic) as revealed by stable water isotope and Hydrochemical signatures
Herschel Island in the southern Beaufort Sea is a push moraine at the northwestern-most limit of the Laurentide Ice Sheet. Stable water isotope (δ18 O, δD) and hydrochemical studies were applied to two tabular massive ground ice bodies to unravel
with a marine influence. Hydrochemical signatures resemble the Herschel Island sediments that are derived from near-shore marine deposits upthrust by the Laurentide ice. A prolonged contact between water feeding the ice bodies and the surrounding sediment
Cette section thématique se compose de trois articles. 1 Se donner de nouveaux moyens pour appréhender l'environnement à l'ère du post-socialisme (T. Herrschel et T. Forsyth). 2 L'édification d'une capacité environnementale en République Tchèque
Modern and Late Holocene retrogressive thaw slump activity on the Yukon Coastal Plain and Herschel Island, Yukon Territory, Canada
Four retrogressive thaw slumps (RTS) located on Herschel Island and the Yukon coast (King Point) were investigated to compare the environmental, sedimentological and geochemical setting and characteristics of zones in active and stabilised slumps
in the Alexandra Fjord-Cape Herschel area of east-central Ellesmere Island. Particular emphasis is placed on the influence of bedrock, lithology and mineralogy on the intensity of physical disintegration under cold arid conditions. Preservation of certain remnant
The AA. perform an analysis of large dark dunes within Moreux Crater and Herschel Crater on Mars using High Resolution Imaging Science Experiment (HiRISE) and Context Camera (CTX) data sets. These data allowing to conduct a detailed analysis of dune
the wind flow direction, leading to the development of a sand transport pathway encircling the central peak of the crater. The dune fields in Herschel Crater are also affected by winds controlled by variable topography as suggested by the presence
Application d'une nouvelle technique pour dater des mesures de glace du sol de l'Arctique canadien occidental. Des échantillons de North Point, de la péninsule Point et de l'île Herschel ont fourni des âges plus jeunes que supposés pour la glace
The aim of this article is : to describe the occurrence in a High Arctic area of some of these white carbonate deposits; to report the results of C 14 age determinations obtained so far from the vicinity of Cape Herschel and elsewhere to give
