FOREWORD THE REGIONAL AQUIFER-SYSTEM ANALYSIS PROGRAM The Regional Aquifer-System Analysis (RASA) Program was started in 1978 following a congressional mandate to develop quantitative apprais­ als of the major ground-water systems of the United States. The RASA Program represents a systematic effort to study a number of the Nation's most important aquifer systems, which in aggregate underlie much of the country and which represent an important component of the Nation's total water supply. In general, the boundaries of these studies are identified by the hydrologic extent of each system and accordingly transcend the political subdivisions to which investigations have often arbitrarily been limited in the past. The broad objective for each study is to assemble geologic, hydrologic, and geochemical information, to analyze and develop an under­ standing of the system, and to develop predictive capabilities that will contribute to the effective management of the system. The use of computer simulation is an important element of the RASA studies, both to develop an understanding of the natural, undisturbed hydrologic system and the changes brought about in it by human activities, and to provide a means of predicting the regional effects of future pumping or other stresses. The final interpretive results of the RASA Program are presented in a series of U.S. Geological Survey Professional Papers that describe the geology, hydrology, and geochemistry of each regional aquifer system. Each study within the RASA Program is assigned a single Professional Paper number, and where the volume of interpretive material warrants, separate topical chapters that consider the principal elements of the investigation may be published. The series of RASA interpretive reports begins with Professional Paper 1400 and thereafter will continue in numerical sequence as the interpretive products of subsequent studies become available.

  • Laurentide Ice Sheet Retreat Around 8000 Years Ago Occurred Over Western Quebec (700-900 Meters/Year)
    The retreat chronology of the Laurentide Ice Sheet during the last 10,000 years and implications for deglacial sea-level rise David Ullman University of Wisconsin-Madison, Department of Geoscience Author Profile Shortcut URL: https://serc.carleton.edu/59463 Location Continent: North America Country: Canada State/Province:Quebec, Labrador City/Town: UTM coordinates and datum: none Setting Climate Setting: Tectonic setting: Type: Chronology Show caption Show caption Show caption Description Much of the world's population is located along the coasts. In a world of changing climate, the rate of sea level rise will determine the ability of these communities to adapt to sea level rise. Perhaps the greatest uncertainty in sea level rise prediction has to do with amount of water melting off of Earth's major ice sheets. Recent decades have seen an accelerated loss of ice from Greenland and Antarctica. These bodies of ice may be prone to change more rapid than expected. Greenland and Antarctica contain enough frozen water, which, if melted could raise sea level by 70 m, but predictions on the rate at which this sea level rise could occur depend on scientists' understanding of the complex physics of ice flow (and on future climate scenarios). Paleoclimate researchers study past climates in hopes of developing a better understanding of our current and future climates. Similarly, understanding past ice sheets will aid in future prediction of ice sheet change. At the end of the Last Glacial Maximum, roughly 20,000 years ago, much of Earth in the northern hemisphere was covered in vast ice sheets.

  • Soil Ecoregions in Latin America 5
    Chapter 1 Soil EcoregionsSoil Ecoregions in Latin Latin America America Boris Volkoff Martial Bernoux INTRODUCTION Large soil units generally reflect bioclimatic environments (the concept of zonal soils). Soil maps thus represent summary documents that integrate all environmental factors involved. The characteristics of soils represent the environmental factors that control the dynamics of soil organic matter (SOM) and determine both their accumulation and degradation. Soil maps thus rep- resent a basis for quantitative studies on the accumulation processes of soil organic carbon (SOC) in soils in different spatial scales. From this point of view, however, and in particular if one is interested in general scales (large semicontinental regions), soil maps have several disadvantages. First, most soil maps take into account the intrinsic factors of the soils, thus the end results of the formation processes, rather than the processes themselves. These processes are the factors that are directly related to envi- ronmental conditions, whereas the characteristics of the soils can be inher- ited (paleosols and paleoalterations) and might no longer be in equilibrium with the present environment. Second, soils seldom are homogenous spatial entities. The soil cover is in reality a juxtaposition of several distinct soils that might differ to various degrees (from similar to highly contrasted), and might be either genetically linked or entirely disconnected. This spatial heterogeneity reflects the con- ditions in which the soils were formed and is expressed differently accord- ing to the substrates and the topography. The heterogeneity also depends on the duration of evolution of soils and the geomorphologic history, either re- gional or local, as well as on climatic gradients, which are particularly obvi- ous in mountain areas.

  • THE INTERIOR PLAINS 23 the Interior Plains.—The Interior Plains Division of Canada Is Part of a Great Plains Region in The
    THE INTERIOR PLAINS 23 The Interior Plains.—The Interior Plains division of Canada is part of a great plains region in the interior of the continent stretching from the gulf of Mexico to the Arctic ocean. In Canada it extends from the Canadian Shield on the east to the Cordillera on the west. At the United States border it has a width of 800 miles but in the extreme northwest at the mouth of the Mackenzie river it is less than 100 miles wide. Throughout most of the region the underlying Palaeozoic, Mesozoic, and Tertiary rocks are nearly flat-lying. In the northwestern part of the area, however, the Franklin range, which lies between Great Bear lake and Mackenzie river, is composed of folded strata. In western Alberta, also, the rocks are folded and faulted. Geologically the region falls into three zones. On the east a narrow plain known as the Manitoba Lowland is developed on flat-lying Palaeozoic strata which range in age from Ordovician to Devonian. In Manitoba the Ordovician beds rest on the Precambrian rocks of the Canadian Shield and commonly present a low escarpment facing the Shield. To the northwest this zone broadens to form the Mackenzie Lowland. Here over wide areas Silurian measures form the base of the Palaeozoic section. In the Franklin mountains, however, red quartzites and sand­ stones of the Mount Clark formation are regarded as of probable Lower Cambrian age. They are succeeded by Middle and Upper Cambrian sandstones and shales. Beds regarded as of probable Ordovician age are also known to occur at the base of mount Kindle east of Wrigley and beneath the Silurian dolomite of the Great Slave Lake area.

He kept a journal as he travelled, and this is how he described the region that would be called the Interior Plains. What I now relate is of the great body of dry land at the east foot of the mountains, the northern part of the forests, and the southern part of the plains, through which roll the Bow and Saskatchewan Rivers with their many branches. The Bow River flows through the most pleasant of the plains, and is the great resort of the bison and the red deer. The snow of the glaciers of the mountains, which everywhere border the west side of these plains, furnish water to form many rivers. The rivers that roll through this immense unbroken body of land of plains and forests are beautifully distributed...
