- Coastal Change Hazards: Hurricanes and Extreme Storms
This project investigates the coastal impacts of hurricanes and extreme storms, such as Hurricanes Isabel (2003), Dennis (1999), Bonnie & Georges (1998), and winter storms, such as those associated with the 1997-98 El Niņo.

El Niņo information with links to a broad range of topics such as Floods, Landslides, Coastal Hazards, Climate, News Releases.
- National Assessment of Coastal Change Hazards
The National Assessment of Coastal Change Hazards is a multi-year undertaking to identify and quantify the vulnerability of U.S. shorelines to coastal change hazards such as the effects of severe storms, sea-level rise, and shoreline erosion and retreat. It will continue to improve our understanding of processes that control these hazards, and will allow researchers to determine the probability of coastal change locally, regionally, and nationally. The Assessment will deliver these data and assessment findings about coastal vulnerability to coastal managers, other researchers, and the general public.
- USGS Circular 1198 - Beyond the Golden Gate - Oceanography, Geology, Biology, and Environmental Issues in the Gulf of the Farallones
The USGS began a major geologic and oceanographic study of the Gulf of the Farallones in 1989. This investigation, the first of several now being conducted adjacent to major population centers by the USGS, was undertaken to establish a scientific data base for an area of 3,400 square kilometers (1,000 square nautical miles) on the Continental Shelf adjacent to the San Francisco Bay region. The results of this study can be used to evaluate and monitor human impact on the marine environment.
- Investigating Climate Change of Western North America - USGS Fact Sheet
The strength and position of the California Current drives the climate of the western United States. When global climate changed, the California Current should have been affected in such a way that evidence of change should be seen in 'proxy' data. If we can see how oceans respond to climate change, we can then infer how the atmosphere has reacted through time. The U.S. Geological Survey is examining a variety of proxy data from western North America and the eastern North Pacific Ocean that might give climate models added validity.
- Fact Sheet 175-99: El Nino Sea-Level Rise Wreaks Havoc in California's SF Bay Region
A color fact sheet describing the effects of El Niņo on the San Francisco Bay Area during the winter of 1997-98. Published by the US Geological Survey. During the winter of 1997-98, wind-driven waves and abnormally high sea levels significantly contributed to hundreds of millions of dollars in flood and storm damage in the San Francisco Bay region. Recent analyses by U.S. Geological Survey (USGS) scientists of nearly 100 years of sea-level records collected near the Golden Gate Bridge found that these abnormally high sea levels were the direct result of that year's El Niņo atmospheric phenomenon. The USGS continues to investigate the causes of such sea-level changes in order to better protect coastal communities from their effects.
- Coral Mortality and African Dust
Why have coral reefs that are bathed in clear oceanic waters throughout much of the Caribbean suffered algal infestation, coral diseases, and near extinction of herbivorous sea urchins from the 1970s through early 1990s? The best known factors detrimental to coral reefs do not apply for many of the affected reefs where human population is low.
- Coral Mortality and African Dust Photo Gallery - Four Decades of Change
Photographs of corals in the Key Largo Coral Reef Marine Sanctuary in Florida illustrate the notable changes that have occurred over the past four decades.
- Coral Reefs in Honduras: Status after Hurricane Mitch - Online Mini-Documentary Movie
"Coral Reefs in Honduras: Status after Hurricane Mitch" is an eight minute mini-documentary featuring geologist Bob Halley describing the USGS response in the wake of Hurricane Mitch to assess the impact of the storm on Caribbean coral reefs off Honduras. Narrated by geologist Terry Edgar.
- Online Mini-Documentary Movie - The Effects of Globally Transported African and Asian Dust on Coral Reef and Human Health
"The Effects of Globally Transported African and Asian Dust on Coral Reef and Human Health" is an eight minute mini-documentary featuring biologist Ginger Garrison, geologist Gene Shinn, chemist Chuck Holmes, and microbiologist Dale Griffin as they explain the deterioration of Caribbean coral health over the past several decades, and how unlocking the key role of trans-Atlantic dust transport has opened the door to understanding the effects and implications of this global phenomenon. Narrated by geologist Terry Edgar.
- Coral Reefs in Honduras: Status after Hurricane Mitch - USGS Open File Report 01-133
In response to the devastation wrought by Hurricane Mitch in Honduras, the United States Geological Survey performed a study to determine the impact the storm had on the coral reef systems of Cayos Cochinos and Roatan, Honduras.

- El Niņo/La Niņa Coastal Comparison Photography - Oregon
La-Niņa Mapping, May, 1999 - A Follow-on Experiment to the El-Niņo Coastal Mapping, October 1997 / April 1998. These pages include pre/post-El-Niņo rainfall data from the Laurel Mountain Monitoring Station, as well as a set of oblique aerial photography of portions of the Oregon coast.
- Monterey Bay Marine Sanctuary Studies
The USGS Monterey Bay National Marine Sanctuary Project gathers, interprets, and distributes geologic information - tools necessary for sound resource protection and preservation of the federally established Monterey Bay National Marine Sanctuary. This web site provides access to that information.
- Coastal Erosion from El-Nino Winter Storms - Oblique Aerial Photography
USGS acquired baseline precision-located oblique still and video photography coverage of over 1000 km of coastline from the west coast of the U.S. in October, 1997, in anticipation of storms generated by the El-Niņo warming of the Pacific Ocean. A follow-up mission was completed in April, 1998 after the storm season.
