Sedimentation and bathymetric change in San Pablo Bay: 1856-1983
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. This repo

Coastal circulation and sediment dynamics along West Maui, Hawaii: Part I: Long-term measurements of currents, temperature, salinity and turbidity off Kahana, West Maui: 2001-2003
No abstract available.AuthorsCurt D. Storlazzi, Bruce E. JaffeMercury-contaminated sediments in the North Bay: A legacy of the Gold Rush
A legacy of the Gold Rush is mercury-contaminated sediments in the Bay. Miners used mercury to extract gold from tailings during the gold rush. A large amount of this mercury (some estimates are as great as 10,000 tons) was lost during extraction to the watershed during the gold rush era. This mercury-contaminated hydraulic mining debris made its way to the Bay.AuthorsBruce E. JaffeHelping coastal communities at risk from tsunamis: the role of U.S. Geological Survey research
In 1946, 1960, and 1964, major tsunamis (giant sea waves usually caused by earthquakes or submarine landslides) struck coastal areas of the Pacific Ocean. In the U.S. alone, these tsunamis killed hundreds of people and caused many tens of millions of dollars in damage. Recent events in Papua New Guinea (1998) and elsewhere are reminders that a catastrophic tsunami could strike U.S. coasts at any tAuthorsEric L. Geist, Guy R. Gelfenbaum, Bruce E. Jaffe, Jane A. ReidEvaluation of landslide hazards with ground-penetrating radar, Lake Michigan coast
Ground-penetrating radar (GPR) and boreholes were used to investigate a landslide-prone bluff at Sleeping Bear Dunes National Lakeshore on the northeastern coast of Lake Michigan. Based on borehole observations, sediment underlying the area is homogeneous, consisting of well-sorted, medium to coarse sand. GPR penetrated up to 20 m deep in these sediments, revealing the late Quaternary stratigraphyAuthorsWalter A. Barnhardt, Bruce E.

AuthorsBruce E. Jaffe, Richard E. Smith, Laura Zink TorresanImpact of an extreme event on the sediment budget: Hurricane Andrew in the Louisiana barrier islands
This paper examines the influence of Hurricane Andrew on the sediment budget of an 80-kilometer section of the Louisiana barrier islands west of the modern Mississippi delta. Because long-term bathymetric change has been extensively studied in this area, excellent baseline data are available for evaluating the impact of Hurricane Andrew. Results show that despite the high intensity of the storm anAuthorsJeffrey H. List, Mark E. Hansen, Asbury H. Sallenger,, Bruce E. JaffeHow much velocity information is necessary to predict sediment suspension in the surf zone?
Instantaneous horizontal water velocity, or velocity to a power, does not contain enough information to predict suspension in the surf zone. Unlike steady uniform flow, more one than one velocity is necessary to parameterize pick-up and mixing of sediment into the water column. Using a velocity history improves predictions of suspension by more carefully specifying flow conditions (including accelAuthorsBruce E. Jaffe, David M. Rubin, Asbury SallengerLarge-scale coastal evolution of Louisiana's barrier islands
The prediction of large-scale coastal change is an extremely important, but distant goal. Here we describe some of our initial efforts in this direction, using historical bathymetric information along a 150 km reach of the rapidly evolving barrier island coast of Louisiana. Preliminary results suggest that the relative sea level rise rate, though extremely high in the area, has played a secondaryAuthorsJeffrey H. List, Bruce E. Jaffe, Asbury H.

Using cartographic and aerial photography data from the years 1853, 1890, 1934, 1956, 1978, 1984, and 1988, shoreline change maps of the Isles Dernieres barrier island arc were constructed. These data were accurately superimposed, using a computer mapping system, which removed projection, datum, scale, and other cartographic inconsistencies. Linear, areal, and perimeter measurements indicate thatAuthorsRandolph A. McBride, Shea Penland, Bruce E. Jaffe, S. Jeffress Williams, Asbury H. Sallenger, Karen A. WestphalMorphodynamic signature of the 1985 hurricane impacts on the northern Gulf of Mexico
Three hurricanes hit Lousiana (LA), Mississippi (MS), Alabama (AL), and the Florida (FL) panhandle in 1985, producing dramatic geomorphic changes in a wide variety of coastal environments. The impact zone for hurricanes Danny, Elena, and Juan stretched 1000 km between the Sabine River in LA to the Apalachicola River in FL. Barrier shorelines experienced repeated intense overwash events, producingAuthorsShea Penland, John R. Suter, Ashbury H. Sallenger, S. Jeffress Williams, Randolph A. McBride, Karen E. Westphal, P.
