San Francisco Bay Area - East Bay (BALT1) Site near Castro Valley, CA

Recent Conditions

The instruments were installed in the spring of 2009 and are used to monitor and detect changes in local conditions.  Soil water content and ground water pressure are monitored at two nests on the same hillslope.  Data for the site include:

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.

Environmental Geochemistry- Coastal Aquifers, Wetlands, and Tidal Exchange

The interface between groundwater and the coastal or intertidal landscape determines the location and migration path of fresh and saline wetlands. These ecosystems interact with the coastal ocean in many ways, much of which is driven by tidal exchange and groundwater discharge, both common coastal processes that deliver water, nutrients, and other materials to nearshore ecosystems, including...

Environmental Geochemistry- Wetland Resilience

Tidal wetlands are key ecosystems because they are unique ecological systems that provide essential habitat for fish, shellfish, birds and other fauna and flora, many of which have great economic importance.  At the same time, tidal wetlands provide critical services to society by serving as a physical barrier between our cities, roads and homes and the rising sea. If healthy and properly...

Environmental Geochemistry- Managed Wetlands

The challenge of wetland persistence is complicated by widespread management and alteration of wetland hydrology, and built infrastructure within migration corridors. Human development and utilization of coastal landscapes in the U.S. during the past several centuries has resulted in loss of approximately half of tidal wetland area, largely due to 1) restriction of tidal flows, through...

Environmental Geochemistry

Coastal Environmental Geochemistry research at the Woods Hole Coastal and Marine Science Center spans multiple ecosystems and topics, including coastal wetlands, aquifers, and estuaries, with the goal of providing data and guidance to federal, state, local, and private land owners and managers on these vital ecosystems.

Remote Sensing Coastal Change

We use remote-sensing technologies—such as aerial photography, satellite imagery, and lidar (laser-based surveying)—to measure coastal change along U.S. shorelines.

Global Geoengineering Research: Modeling

Prediction of the severity of ground failure in Quaternary deposits is a critical component of hazard studies. Model development in our project is focused on design and application of methods for quantitative assessment of ground deformation potential.
