Regional studies increase knowledge of specific coastal and marine geologic systems. Catastrophic event studies address the effect that rare or large-magnitude events have on coastal and marine geologic systems. Hurricanes, earthquakes, tsunamis, floods, and pollutant or nutrient discharges require rapid response, and a long-term commitment to the acquisition of baseline data is needed. Long-term observations define the time scales and the magnitude of change in geologic systems. Data from long-term observations provide a range of conditions, including catastrophic and rare events, for use in models.
Assessments provide a systematic evaluation of the status of geologic systems or processes.
These activities may be undertaken regionally but are leading to national synthesis. The program also provides coastal and marine geologic expertise for national assessments l ed by other Federal agencies. Environmental Quality and Preservation Geologic issues influence the health of coastal and marine environments and understanding of geologic processes is a necessary component of efforts to protect and preserve these environments over short and long time-scales. Determine the geologic controls on ground-water resources and hazardous waste isolation. Program projects related to marine pollution and waste disposal, wetlands, coral reefs, marine reserves, and benthic habitats will lead to improved understanding of geologic processes so that natural and man caused changes to the coast, sea floor, and lake floors can be predicted.
