Exploring caves: teaching packet for grades K-3
Water Resources Division, U.S. Geological Survey
1998, Report
"Exploring Caves" is an interdisciplinary set of materials on caves for grades K-3. Caves entail at least five scientific disciplines: earth science, hydrology, mapping, biology, and anthropology. Each of these disciplines involves a unique content area as well as the development of particular intellectual skills. This unit aims at helping...
Assemblage organization in stream fishes: Effects of environmental variation and interspecific interactions
Gary D. Grossman, R. E. Ratajczak Jr., M. M. Crawford, Mary C. Freeman
1998, Ecological Monographs (68) 395-420
We assessed the relative importance of environmental variation, interspecific competition for space, and predator abundance on assemblage structure and microhabitat use in a stream fish assemblage inhabiting Coweeta Creek, North Carolina, USA. Our study encompassed a 10–yr time span (1983–1992) and included some of the highest and lowest flows in...
Water-chemistry and on-site sulfur-speciation data for selected springs in Yellowstone National Park, Wyoming, 1994-1995

1998, Open-File Report 98-574
Forty-two water analyses are reported for samples collected at 8 hot springs and their overflow drainages, two geysers, and two ambient-temperature acid streams in Yellowstone National Park during 1994-95. These water samples were collected and analyzed as part of the initial research investigations on sulfur redox speciation in the hot springs of Yellowstone...
Design, operation, and data analysis for a wireline packer system in open boreholes, with field-test results from Belvidere, Illinois

1998, Open-File Report 98-759
A long-term perspective of erosion and deposition in San Francisco Bay is vital to understanding and managing wetland change, harbor and channel siltation, and other sediment-related phenomena such as particle and particle-associated substance (pollutants, trace metals, etc.) transport and deposition. A quantitative comparison of historical hydrographic surveys provides this perspective....
