FUNDAMENTAL MODAL BEHAVIOR OF AN EARTHQUAKE-EXCITED BRIDGE.
A. G. Brady, M. Çelebi
1986, Conference Paper
The magnitude 6. 1 Morgan Hill, California, earthquake of April 24, 1984, produced a set of acceleration records at the freeway overpass in San Jose carrying I-280/I-680 across U. S. 101, 12 km from the epicenter. Peak accelerations reached 0. 10 g at ground level and 0. 16 g in...
Evidence for a stronger oxygen-minimum zone off central California during late Pleistocene to early Holocene
J.V. Gardner, E. Hemphill-Haley
1986, Geology (14) 691-694
Of 31 deep-sea cores collected along the central California continental slope, 18 have distinctly laminated sediment at depth, but none have laminations in the top few centimetres. The cores with laminated facies are restricted to water depths between 508 and 1508 m, but...

Regression approximations for transport model constraint sets in combined aquifer simulation-optimization studies
William M. Alley
1986, Water Resources Research (22) 581-586
Problems involving the combined use of contaminant transport models and nonlinear optimization schemes can be very expensive to solve. This paper explores the use of transport models with ordinary regression and regression on ranks to develop approximate response functions of concentrations at critical locations as a function of pumping and...

Magmatic inclusions in silicic and intermediate volcanic rocks
Charles R. Bacon
1986, Journal of Geophysical Research B: Solid Earth (91) 6091-6112
Fine‐grained ellipsoidal inclusions from a few millimeters to over l m in size are present in many intermediate to silicic lava flows and domes. Only recently has it become widely accepted that such inclusions are chilled blobs of magma. Their magmatic origin is manifested by vesicularity and high groundmass porosity,...

B.G. Waller
1985, Water-Resources Investigations Report 85-4152
South-central Florida (the Kissimmee Basin) experienced a severe drought during 1980-82, causing Lake Okeechobee--the largest surface-water storage area in south Florida--to reach the lowest stage ever recorded, 9.75 feet above sea level, on July 29, 1981. A prolonged period of deficient rainfall extended from June 1980 to March 1982. On...

Drilling on Leg 80 of the Deep Sea Drilling Project-International Phase of Ocean Drilling was conducted on a transect of four sites (548-551) across the continent-ocean boundary at Goban Spur, a prominent southwest-trending structural and topographic high on the Irish continental slope. Drilling results have been integrated with physiographic, gravimetric,...
Leaching of plutonium from a radioactive waste glass by eight groundwaters from the western United States

1985, Nuclear Technology (70) 133-140
The leachability of a radioactive waste glass formulated to Battelle Pacific Northwest Laboratory specification 80-270 has been studied using eight actual groundwaters with a range of chemical compositions as leachants. Waters collected from the Grande Ronde Basalt (Washington State) and from alluvial deposits in the Hualapai Valley (Arizona) were the...
