Interactive maps and databases showing geospatial, biologic, and ecological aspects of the upper Mississippi River. Includes water quality, fish species, and vegetation distribution as well as geographic reference information.
Proposed removal of dams will change the characteristics of stream flow and will affect fish that swim upstream to spawn. A mathematical model of the river flow tells us where the likely problems will be located and how the flow will change.
Includes hydrographic information from 2000 to last seven days, water-quality data, elevation, area, and capacity data and publications on Devils Lake, North Dakota in the Red River of the North basin.
Publication (PDF format) in three parts on the biostratigraphy and lithostratigraphy of the Ibexian Series in the North American Ordovician, with sections on the southern Egan Range, Nevada and the biostratigraphy of the eastern Great Basin.
An assessment of the potential protective effects on coastal marshes in Louisiana of building barrier berms seaward of the existing barrier islands and inlets to help block or reduce the onshore spread of oil from the Deepwater Horizon oil spill.
Information from climate model forecasts, projections of future flows, paleoclimatic indicators, timing of snowmelt, airborne dust, and the effects on vegetation of troublesome pest species indicate the nature and severity of problems looming.
