Stratigraphic framework maps of the nearshore area of southern Long Island from Fire Island to Montauk Point, New York
David S. Foster, B. Ann Swift, William C. Schwab
1999, Open-File Report 99-559
The maps presented in this report (depth to Coastal Plain unconformity, Quaternary sediment thickness, paleochannel thickness, and modern sand thickness) are helpful for determining sand-resource availability for beach nourishment programs and understanding the influence that the inner-shelf framework of southern Long Island has on coastal processes and evolution. The maps...

A physically-based earthquake recurrence model for estimation of long-term earthquake probabilities
William L. Ellsworth, Mark V. Matthews, Robert M. Nadeau, Stuart P. Nishenko, Paul A. Reasenberg, Robert W. Simpson
1999, Open-File Report 99-522
A physically-motivated model for earthquake recurrence based on the Brownian relaxation oscillator is introduced. The renewal process defining this point process model can be described by the steady rise of a state variable from the ground state to failure threshold as modulated by Brownian motion. Failure times in this model...

1999, Open-File Report 99-544
The Southwest Mineral and Environmental Investigations Project is designed to address issues raised by rapid urban development in the basins of the southwestern U.S. These issues require objective geoscientific data that can be used by land managers and stakeholders to develop informed land and water use strategies. The project integrates...
Preliminary digital map of cryptocrystalline occurrences in northern Nevada
Lorre A. Moyer
1999, Open-File Report 99-523
The purpose was to identify potential cryptocrystalline material sources for tools used by indigenous people of the northern Nevada portion of the Great Basin. Cryptocrystalline occurrence data combed from the U.S. Geological Survey's Mineral Resources Data System (MRDS, 1995) were combined with sites described in Nevada rockhound guides and entered...
Precipitation, atmospheric deposition, streamflow, and water-quality data from selected sites in the city of Charlotte and Mecklenburg County, North Carolina, 1997–98
Kathleen M. Sarver, W. F. Hazell, J. B. Robinson
1999, Open-File Report 99-273
Precipitation data were collected at 46 precipitation sites and 3 atmospheric deposition sites, and hydrologic data were collected at 6 stream sites in the vicinity of Charlotte and Mecklenburg County, North Carolina, from July 1997 through September 1998. Data were collected to identify the type, concentration, and amount of nonpoint-source...

1999, Open-File Report 99-581
Sidescan sonar imagery and high-resolution seismic-reflection profiles were collected in Las Vegas Bay and Boulder Basin of Lake Mead to determine the surficial geology as well as the distribution and thickness of sediment that has accumulated in these areas of the lake since the completion of Hoover Dam in 1935...
