Resilience and Recovery: Science for Future Reefs

Coral reefs are facing increasing stress from climate change (elevated sea-surface temperatures and acidification), combined with local stresses from over-fishing and sedimentation and other sources of land-based pollution. In light of the potential for these stressors to increase the rate of coral reef degradation to epidemic levels, coral reef scientists and managers world-wide are shifting...

Sea-Level Rise and Climate Change Impacts to Reefs

Based on rates of vertical reef accretion in Hawaiʻi and throughout the Pacific, it is unlikely that reefs there and other locations will keep pace with the rising sea levels, and their inability to do so will lead to subtle but important changes in selected physical processes on some coral reefs.

Circulation and Sediment, Nutrient, Contaminant, and Larval Dynamics on Reefs

The Problem

Terrigenous sediment run-off and deposition on coral reefs can significantly impact coral health by blocking light and inhibiting photosynthesis, directly smothering and abrading coral, and triggering increases in macro algae. The delivery of sediment and pollutants to reefs have increased globally as a response to human-induced changes to watersheds, as...

Estuaries and large river deltas in the Pacific Northwest

Essential habitat for wild salmon and other wildlife borders river deltas and estuaries in the Pacific Northwest. These estuaries also support industry, agriculture, and a large human population that’s expected to double by the year 2060, but each could suffer from more severe river floods, higher sea level, and storm surges caused by climate change.

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.

CMGP conducts integrated mapping of the coastal and marine environment to define offshore hazards and sediment processes, support habitat and resource management, and monitor change. CMGP is an innovator in mapping and laboratory analyses, whose expertise is sought by other governmental agencies, educational institutions, and private companies.

Marsh shorelines of the Massachusetts coast from 2013-14 topographic lidar data

The Massachusetts Office of Coastal Zone Management (CZM) launched the Shoreline Change Project in 1989 to identify erosion-prone areas of the Massachusetts coast. This update included a marsh shoreline, which was defined to be the tonal difference between low- and high-marsh seen in ortho-photos. Further cooperation between CZM and the U.S. Geological Survey (USGS) has resulted in another...

Collection, analysis, and age-dating of sediment cores from salt marshes on the south shore of Cape Cod, Massachusetts, from 2013 through 2014

Elevation of the marsh surface was measured with RTK-GPS to evaluate where the marsh falls within the current tidal frame. The historic marsh surface elevation was then reconstructed using the calculated age of each depth interval and its elevation, assuming that elevations within this shallow zone (less than 30 cm) have been preserved for the past century.
