-lake section of GreatSlaveLake. The long-term objectives of this research include modeling the heat and mass exchange components, assessing potential climate change impacts, and quantifying the interannual variabilities. These analyses
This paper summarizes the cross-lake variations of meteorology, evaporation, heat fluxes, thermal response, heat content, and physical limnological processes based on 1998 summer and 1998/1999 winter over-lake measurement platforms within the main
are an important step in understanding the relationship between the physical regime and ecosystem responses in large northern lakes.

Introduction, en 1963, d'un troupeau de 18 bisons d'Amérique dans une réserve naturelle au bord du GreatSlaveLake, Northwest Territories, Canada| sur une zone de 18 000 km. Le troupeau dépasse les 700 têtes en 1981, et ne s'est pas encore divisé
The A. presents some synoptic photos from the material of APOLLO-9 and LANDSAT-I, which refer to large earthy astroblemes. Earlier science has not known about their existence, or as in the case of the GreatSlaveLake the basin genesis has been

The purpose of this paper is to apply the sociobiophysical evolution model (Grzybowski 1986| Grzybowski, Slocombe 1988) to the GreatLakes Basin and to explore its implications for management of the Basin.
Highest pluvial-lake shorelines and Pleistocene climate of the Western Great Basin

Shoreline altitudes of several pluvial lakes in the western Great Basin of North America record successively smaller lakes from the early to the late Pleistocene. This decrease in lake size indicates a long-term drying trend in the regional climate
that is not seen in global marine oxygen-isotope records. The previously unknown lake levels also reflect significant changes in tectonics, and (or) drainage-basin configurations, and could have facilitated migration of aquatic species in the Great Basin.
The AA. present the diachronic nomenclature for finer subdivisions of time and events since the penultimate glaciation (last 130,000 years), recognized in the eastern and northern GreatLakes area centered on Ontario. A deliberate attempt was made
The Mormon experience : the plains as Sinai, the Great Salt Lake as the Dead Sea, and the Great Basin as desert-cum-promised land
The experiences of the members of the Church of Jesus Christ of Latter-day Saints in migrating across the Great Plains to the valley of the Great Salt Lake, in colonizing the Wasatch oasis, and in occupying major portions of the Great Basin gave

In this paper, diachronic and event classifications are proposed for the GreatLakes region. Well-established names, including Wisconsin, Sangamon, and Illinois, are used at the episode (or glaciation/interglaciation) rank without significant
redefinition. The Hudson Episode (Interglaciation) is introduced for postglacial time, the current interglacial interval. The Wisconsin Episode is divided into the Ontario, Elgin, and Michigan Subepisodes in the eastern and northern parts of the GreatLakes
region and into the Athens and Michigan Subepisodes in the southern and western parts of the GreatLakes region.
Geomorphology applied to flooding problems of closed-basin lakes...specifically Great Salt Lake, Utah

This paper reports on how geomorphic evidence has contributed to an understanding and definition of flooding hazards associated with closed-basin lakes in the Great Basin of the western United States and specifically with the largest of these lakes
, Utah's Great Salt Lake. The understanding of past lake fluctuations based on geomorphic and historic evidence and the knowledge of effects of wind and earthquakes on lakes provide sufficient information to be used in estimating flooding risks associated

Salt dissolution features in saline lakes of the northern Great Plains, western Canada

Large-scale salt dissolution is an important process affecting the sediments of many of the saline lakes in the northern Great Plains region of western Canada. The most easily recognized features of this salt karst are water-filled chimneys
, vertical shafts, and collapse structures. Because these salt karst features can affect large vertical sections of the sediment fill in the lakes, their recognition is of fundamental importance in attempting to use the stratigraphic records of the basins

The Great Salt Lake is a highly complex system, consisting of physical and chemical lake properties and environmental and societal subsystems. Using a system approach, this article aims to identify some of the key components of this environmental
