Estuarine Processes, Hazards, and Ecosystems-Study Sites

Estuaries are dynamic environments where complex interactions between the atmosphere, ocean, watershed, ecosystems, and human infrastructure take place. They serve as valuable ecological habitat and provide numerous ecosystem services and recreational opportunities. However, they are modified by physical processes such as storms and sea-level rise, while anthropogenic impacts such as nutrient...

Hurricane Sandy Response- Linking the Delmarva Peninsula's Geologic Framework to Coastal Vulnerability

The Delmarva Peninsula is a 220-kilometer-long headland, spit, and barrier island complex that was significantly affected by Hurricane Sandy. In order to better constrain controls on coastal vulnerability and evolution, the region’s sediment sources, transport pathways and sediment sinks must be identified. This project defines the geologic framework of the Delmarva coastal system through...

Water-Quality Inventory Pesticides in the Golden Gate National Recreation Area

In 1998, all urban creeks in the San Francisco Bay Area were added to the Clean Water Act Section 303d list due to known or suspected diazinon impairment. Diazinon is an organophosphorus insecticide used on lawns, and fruit and vegetables. This pesticide has since been "phased out" and has not been available for purchase since late 2004. Diazinon use is declining and is being replaced by other...

Using Video Imagery to Study Wave Dynamics: Isla Verde

Four video cameras overlook the coast at Isla Verde in San Juan, Puerto Rico. Two of them focus on the shoreline: Camera 1 looks at the nearby beach and eastward along the shore, and Camera 2 looks farther away to the eastern end of the beach. The other two look out across the reefs: Camera 3 to the north-northwest, and Camera 4 to the northeast.
