National Assessment of Shoreline Change Part 3: Historical Shoreline Change and Associated Coastal Land Loss Along Sandy Shorelines of the California Coast

Beach erosion is a chronic problem along many open-ocean shores of the United States. As coastal populations continue to grow and community infrastructures are threatened by erosion, there is increased demand for accurate information regarding past and present trends and rates of shoreline movement. There is also a need for a comprehensive analysis of shoreline movement that is consistent from one

Seaside, Oregon tsunami pilot study— Modernization of FEMA flood hazard maps

FEMA Flood Insurance Rate Map (FIRM) guidelines do not currently exist for conducting and incorporating tsunami hazard assessments that reflect the substantial advances in tsunami research achieved in the last two decades; this conclusion is the result of two FEMA-sponsored workshops and the associated Tsunami Focused Study. Therefore, as part of FEMA's Map Modernization Program, a Tsunami Pilot S

A history of intertidal flat area in south San Francisco Bay, California: 1858 to 2005

A key question in salt pond restoration in South San Francisco Bay is whether sediment sinks created by opening ponds will result in the loss of intertidal flats. Analyses of a series of bathymetric surveys of South San Francisco Bay made from 1858 to 2005 reveal changes in intertidal flat area in both space and time that can be used to better understand the pre-restoration system. This analysis a

usSEABED: Gulf of Mexico and Caribbean (Puerto Rico and U.S. Virgin Islands) offshore surficial sediment data release

Over the past 50 years there has been an explosion in scientific interest, research effort and information gathered on the geologic sedimentary character of the United States continental margin. Data and information from thousands of publications have greatly increased our scientific understanding of the geologic origins of the shelf surface but rarely have those data been combined and integrated.

Coastal circulation and sediment dynamics in Hanalei Bay, Kaua'i, Hawaii: Part II: Tracking recent fluvial sedimentation: Isotope stratigraphy obtained in Summer 2005

Delivery and dispersal of fluvial sediment in Hanalei Bay, Kaua’i, Hawaii, have important implications for the health of local coral reefs. The reef community in Hanalei Bay represents a relatively healthy ecosystem. However, the reefs are periodically stressed by storm waves, and increases in sediment and dissolved substances from the Hanalei River have the potential to cause additional stress. I

Digital single-channel seismic-reflection data from western Santa Monica basin

During a collaborative project in 1992, Geological Survey of Canada and United States Geological Survey scientists obtained about 850 line-km of high-quality single-channel boomer and sleeve-gun seismic-reflection profiles across Hueneme, Mugu and Dume submarine fans, Santa Monica Basin, off southern California. The goals of this work were to better understand the processes that lead to the format

Overview: DVD-video disc set of seafloor transects during USGS research cruises in the Pacific Ocean

Many USGS research programs involve the gathering of underwater seafloor video footage. This footage was captured on a variety of media, including Beta III and VHS tapes. Much of this media is now deteriorating, prompting the migration of this video footage onto DVD-Video discs. Advantages of using DVD-Video discs are: less storage space, ease of transport, wider distribution, and non-degradationa

Transport pathways in the lower reaches of Hood Canal

In 2003, studies revealed that the waters in the lower reaches of Hood Canal in Washington State had very low dissolved-oxygen concentrations, low enough to cause some fish kills between June and October of that year. In order to determine the transport patterns and the persistence of the low oxygen level in this portion of the canal, the U. S. Geological Survey deployed two instrumented platforms
