Effects of water-management alternatives on streamflow in the Ipswich River basin, Massachusetts
Philip J. Zarriello
2002, Open-File Report 2001-483
Management alternatives that could help mitigate the effects of water withdrawals on streamflow in the Ipswich River Basin were evaluated by simulation with a calibrated Hydrologic Simulation Program--Fortran (HSPF) model. The effects of management alternatives on streamflow were simulated for a 35-year period (1961-95). Most alternatives examined increased low flows...
Volatile Organic Compounds, Specific Conductance, and Temperature in the Bottom Sediments of Mill Pond, Ashland, Massachusetts, April 2001

2002, Open-File Report 2002-35
A plume of volatile organic compounds in ground water extends northward from the former Nyanza Property in Ashland, Massachusetts, and discharges into the Sudbury River and the upstream end of Mill Pond. A network of polyethylene-membrane passive-vapor-diffusion samplers was installed in February 2001 to help define the lateral extent of...

Jared D. Abraham, Craig Moulton, Philip J. Brown II
2002, Open-File Report 2002-63
In October 2001, the U.S. Geological Survey conducted borehole radar surveys of an oil injection experiment at the Colorado School of Mines (CSM), in Golden Colorado using the prototype U.S. Geological Survey (USGS)-developed directional borehole radar system (DBOR). A explanation of the system can be...

A logistic regression equation for estimating the probability of a stream flowing perennially in Massachusetts
Gardner C. Bent, Stacey A. Archfield
2002, Water-Resources Investigations Report 2002-4043
A logistic regression equation was developed for estimating the probability of a stream flowing perennially at a specific site in Massachusetts. The equation provides city and town conservation commissions and the Massachusetts Department of Environmental Protection with an additional method for assessing whether streams are perennial or intermittent at a...

U.S. coral reefs; imperiled national treasures
M.E. Field, S.A. Cochran, K.R. Evans
2002, Fact Sheet 025-02
Coral reefs are home to 25% of all marine species. However, the tiny colonial animals that build these intricate limestone masses are dying at alarming rates. If this trend continues, in 20 years the living corals on many of the world's reefs will be dead and the ecosystems that depend...

Chromium isotopes and the fate of hexavalent chromium in the environment
Andre S. Ellis, Thomas M. Johnson, Thomas D. Bullen
2002, Science (295) 2060-2062
Measurements of chromium (Cr) stable-isotope fractionation in laboratory experiments and natural waters show that lighter isotopes reacted preferentially during Cr(VI) reduction by magnetite and sediments. The 53Cr/52Cr ratio of the product was 3.4 ± 0.1 per mil less than that of the reactant.53Cr/52Cr shifts in water samples indicate the extent...
Analysis of long-period events recorded at Mount Etna (Italy) in 1992, and their relationship to eruptive activity
S. Falsaperla, Eugenio Privitera, Bernard A. Chouet, Phillip B. Dawson
2002, Journal of Volcanology and Geothermal Research (114) 419-440
Seismic activity recorded at Mount Etna during 1992 was characterized by long-period (LP) events and tremor with fluctuating amplitudes. These signals were associated with the evolution of the eruptive activity that began on December 14, 1991. Following the occurrence of numerous volcano-tectonic...
Flow and sediment suspension events on the inner shelf of central California

2002, Marine Geology (181) 195-213
The US Geological Survey conducted a field experiment in the late spring and early summer of 1998 off northern Santa Cruz County, California, to study sediment fluxes along the central California shelf. As part of this study, a bottom-mounted instrument package was deployed in a sediment-filled paleo-stream channel (h=12 m)...
Cordilleran-margin quartzites in Baja California – implications for tectonic transport
G.E. Gehrels, John H. Stewart, Keith B. Ketner
2002, Earth and Planetary Science Letters (199) 201-210
One of the current controversies in Cordilleran tectonics concerns the position of Baja California prior to ∼300 km of opening of the Gulf of California. Geologic arguments, together with paleomagnetic results from Lower Cretaceous volcanic rocks, suggest that the rocks of the Baja Peninsula formed and evolved along the coast...

2002, Bonneville Power Administration Report DOE/BP-00000022-1
The fundamental influence of fluid dynamics on aquatic organisms is receiving increasing attention among aquatic ecologists. For example, the importance of turbulence to ocean plankton has long been a subject of investigation (Peters and Redondo 1997). More recently, studies have begun to emerge that explicitly consider the effects of shear...

Richard S. Sojda
2002, Thesis
The number of trumpeter swans (Cygnus buccinator) breeding in the Tri-State area where Montana, Idaho, and Wyoming come together has declined to just a few hundred pairs. However, these birds are part of the Rocky Mountain Population which additionally has over 3,500 birds breeding in Alberta, British Columbia, Northwest Territories,...
Discharge measurements using a broad-band acoustic Doppler current profiler
Michael R. Simpson
2002, Open-File Report 2001-1
The measurement of unsteady or tidally affected flow has been a problem faced by hydrologists for many years. Dynamic discharge conditions impose an unreasonably short time constraint on conventional current-meter discharge-measurement methods, which typically last a minimum of 1 hour. Tidally affected discharge can change more than 100 percent during...
