Post-Mazama (7 KA) faulting beneath Upper Klamath Lake, Oregon Post-Mazama (7 KA) faulting beneath Upper Klamath Lake, Oregon
High-resolution seismic-reflection profiles (3.5 kHz) show that a distinctive, widespread reflection occurs in the sediments beneath Upper Klamath Lake, Oregon. Coring reveals that this reflection is formed by Mazama tephra (MT), about 7 ka in age. The MT horizon is faulted in many places and locally displaced by as much as 3.1 m. Differential displacement of multiple horizons indicates...

Climatic variability in the eastern United States over the past millennium from Chesapeake Bay sediments Climatic variability in the eastern United States over the past millennium from Chesapeake Bay sediments
Salinity oscillations caused by multidecadal climatic variability had major impacts on the Chesapeake Bay estuarine ecosystem during the past 1000 yr. Microfossils from sediments dated by radiometry (14C, 137Cs, 210Pb) and pollen stratigraphy indicate that salinity in mesohaline regions oscillated 10-15 ppt during periods of extreme drought (low fresh-water discharge) and wet climate...

Time-averaged fluxes of lead and fallout radionuclides to sediments in Florida Bay Time-averaged fluxes of lead and fallout radionuclides to sediments in Florida Bay
Recent, unmixed sediments from mud banks of central Florida Bay were dated using 210Pb/226Ra, and chronologies were verified by comparing sediment lead temporal records with Pb/Ca ratios in annual layers of coral (Montastrea annularis) located on the ocean side of the Florida Keys. Dates of sediment lead peaks (1978±2) accord with prior observations of a 6 year lag between the occurrence...

Water Resources Data Massachusetts and Rhode Island Water Year 1999 Water Resources Data Massachusetts and Rhode Island Water Year 1999
INTRODUCTION The Water Resources Division of the U.S. Geological Survey, in cooperation with State agencies, obtains a large amount of data pertaining to the water resources of Massachusetts and Rhode Island each water year. These data, accumulated during many water years, constitute a valuable data base for developing an improved understanding of the water resources of the States. To...

Water resources data, Ohio, water year 1999, Volume 1. Ohio River Basin excluding project data Water resources data, Ohio, water year 1999, Volume 1. Ohio River Basin excluding project data
Water-resources data for the 1999 water year for Ohio consist of records of stage, discharge, and water quality of streams; stage and contents of lakes and reservoirs; and water levels and water quality of ground-water wells. This report, in two volumes, contains records for water discharge at 120 gaging stations and 69 partial-record sites; water levels at 187 observation wells and 26...

Hydrologic aspects of the 1998-99 drought in the Delaware River basin Hydrologic aspects of the 1998-99 drought in the Delaware River basin
A notable drought in the Delaware River Basin during late 1998 and most of 1999 had a major effect on surface and subsurface components of the hydrologic system. The drought conditions resulted from anomalous patterns in the general atmospheric circulation that diverted Gulf and subtropical Atlantic moisture away from the basin. From September 1998 to August 1999, the accumulated...

Effects of coal-mine drainage on stream water quality in the Allegheny and Monongahela River Basins — Sulfate transport and trends Effects of coal-mine drainage on stream water quality in the Allegheny and Monongahela River Basins — Sulfate transport and trends
In 1980, the Allegheny and Monongahela Rivers transported a sulfate load of 1.2 million and 1.35 million tons, respectively, to the Ohio River at Pittsburgh. The Monongahela River Basin had a sulfate yield of 184 tons per square mile per year compared to 105 tons per square mile per year for the Allegheny River Basin. Within the large Allegheny and Monongahela River Basins, the subbasins...
