Water resources of Monroe County, New York, water years 1997-99, with emphasis on water quality in the Irondequoit Creek basin—Atmospheric deposition, ground water, streamflow, trends in water quality, and chemical loads to Irondequoit Bay
Donald A. Sherwood
2003, Water-Resources Investigations Report 2002-4221
Irondequoit Creek drains 169 square miles in the eastern part of Monroe County. Over time, nutrients transported by Irondequoit Creek to Irondequoit Bay on Lake Ontario have contributed to the eutrophication of the bay. Sewage-treatment-plant effluent, a major source of nutrients to the creek and its tributaries, was eliminated from...
Geology of Paleozoic Rocks in the Upper Colorado River Basin in Arizona, Colorado, New Mexico, Utah, and Wyoming, Excluding the San Juan Basin
Arthur L. Geldon
2003, Professional Paper 1411-A
The geology of the Paleozoic rocks in the Upper Colorado River Basin in Arizona, Colorado, New Mexico, Utah, and Wyoming, was studied as part of the U.S. Geological Survey's Regional Aquifer-System Analysis Program to provide support for hydrogeological interpretations. The study area is segmented by numerous uplifts and basins caused...
Geologic map of the MTM 85080 Quadrangle, Chasma Boreale Region of Mars
Kenneth E. Herkenhoff
2003, IMAP 2753
The polar deposits on Mars probably record martian climate history over the last 107 to 109 years (for example, Thomas and others, 1992).
