A vegetation map reconstructed for the Japanese Archipelago (based upon pollen data from 28 sites and plant macrofossil data from 33 sites) at the time of lastglacialmaximum shows that coniferous forests covered extensive areas of the land. Boreal
Glacial geomorphology around the Northern Patagonian Icefield indicates that a number of fast-flowing outlet glaciers drained the icefield during the LastGlacialMaximum. Here, a detailed regional map of glacial landforms around the Northern
of the Northern Patagonian Icefield at the LastGlacialMaximum is not accurately represented in existing numerical ice-sheet models.
Alpine evidence for atmospheric circulation patterns in Europe during the LastGlacialMaximum
the atmospheric circulation and associated precipitation patterns responsible for the ice buildup in the Alps during the last glaciation and 2) an explanation for the nonsynchronous maximumglacial extents in the Alps, the Pyrénées, and the surrounding low
The AA. present a reconstruction of the late Quaternary paleoclimate history in central Europe with special emphasis on the period of ice buildup following the last (Eemian) interglaciation. Special attention is focused on 1) reconstructing

The Peoria Loess of south-central Nebraska, deposited approximately during the LastGlacialMaximum, can be subdivided into three zones: an upper laminated loess and a lower massive loess, separated by a dark gley zone in which bison bones
Cosmogenic nuclide chronology of pre-lastglacialmaximum moraines at Lago Buenos Aires, 46°S, Argentina
In this paper, exposure ages are presented for glacial deposits older than the lastglacialmaximum. The chronology demonstrates that a major mountain glaciation occurred during marine oxygen isotope stage 6 in Patagonia and indicates
Reconstruction of the Ross ice drainage system, Antarctica, at the LastGlacialMaximum
Glacial and paleoclimatic history of the Ross ice drainage system of Antarctica. Special issue
The AA. present a revised reconstruction of the Ross ice drainage system of Antarctica at th LastGlacialMaximum (LGM) based on a recent convergence of terrestrial and marine data. The Ross drainage system includes all ice flowlines that enter
Circulation in the Gulf of Mexico during the lastglacialmaximum 18000 years ago
Lors du dernier maximum glaciaire (il y a 18000 ans), les eaux de surface du Golfe du Mexique étaient plus froides et plus salées, et décrivaient un mouvement anticyclonique. (JRV).
Lastglacialmaximum in China: comparison between land and sea
As a result of the sea-level drop at the lastglacialmaximum, the size and configurations of the Chinas Seas changed greatly. This paper is an attempt to compare the available paleoenvironmental data yielded by deposits of the China mainland
Absence of lastglacialmaximum records in lowlan tropical forests
Environmental conditions of the lowland tropical forests during the lastglacialmaximum (LGM) between ca 20,000 and 18,000 C 14 yr B.P., are reevaluated in terms of dating control and lithology analyzed in seven pollen records from South America
Extent and timing of the lastglacialmaximum in Southwestern Alaska
The AA. report here on stratigraphic sections relevant to the timing of the lastglacialmaximum (LGM) in southwestern Alaska, the region between Cook Inlet and Unimak Island, including the Kodiak archipelago. This work has concentrated
Paleoproductivity evolution off central Chile from the LastGlacialMaximum to the Early Holocene
A geochemical and paleontological reconstruction of paleoproductivity, upwelling intensity and sea surface temperature (SST) off central Chile at 35°S reveals marked changes from the LastGlacialMaximum (LGM) through the Early Holocene. The AA
Cosmogenic radionuclide evidence for the limited extent of lastglacialmaximum glaciers in the Tanggula Shan of the central Tibetan Plateau
Cosmogenic radionuclide (CRN) exposure ages provide evidence for the limited extent of lastglacialmaximum glaciers in the Tanggula Shan, central Tibetan Plateau. The most extensive advances occurred during or before marine oxygen isotope stage 6
The article deals with glacial remains from the lastglacialmaximum in the Logar Valley (Kamnik-Savinja Alps). The AA. tried to reinterpret the findings written so far and to prepare a new proposal of the circumference of the lastglacialmaximum
in this area. The numerical analysis was based on the findings gained with field work. According to the findings, the maximum glacier extent was drawn and a three-dimensional reconstruction of the topography of the surface was created. - (IKR)

New radiometric and geomorphologic evidences of a lastglacialmaximum older than 18 ka in SW European mountains : the exemple of Redes Natural Park (Cantabrian Mountains, NW Spain)

of glacier evolution established in the Pyrénées, with a glacialmaximum phase for the lastglacial period older than 18 ka.
The aim of this work is to date glacial events in Redes Natural Park, in order to establish if the timing of these events is similar to comparable events in the Pyrénées. The chronological data presented in this work are consistent with the model

The main aim of this paper is to contribute to a resolution of the described controversy on the limit of the last glacier, and to provide an improved description and interpretation of the late Weichselian glaciation on western Svalbard
Paleoecology of central Kentucky since the LastGlacialMaximum
Climatic variation ; Glacial features ; Holocene ; Kentucky ; Paleo-ecology ; Palynology ; Pollen diagrams ; Quaternary ; United States
In this paper, the AA. present paleoecological data from Jackson Pond, Kentucky, which is located 190 km south of the full-glacial limit of the Laurentide Ice Sheet and the sediments of which continuously span the past 20,000 radiocarbon years
maximum, dated between 30 000 and 11 000 B.P., was relatively cold and dry compared with the warmer, more humid climate of the Holocene and the interstade preceding the lastglacialmaximum. General atmospheric circulation models for the polar latitudes
at the time of the lastglacialmaximum show an intensification of the southern westerlies, apparently a result of the expansion of ice cover in Antarctica.
Late-Quaternary paleoecological and glacial evidence from the higher latitudes of the Southern Hemisphere implies overall uniformity of large-scale glacial and interglacial climatic fluctuations for the past 40 000 yr. Climate of the lastglacial
