Guy Gelfenbaum
Oceanographer Emeritus with the USGS Pacific Coastal and Marine Science Center in Santa Cruz, California
Ecosystem Dynamics, Project Chief: Coastal Habitats in Puget Sound - The goal of these projects is to develop scientific information and tools to support natural resource managers in the adaptive management of critical nearshore ecosystems in Puget Sound
Large-Scale Coastal Change, Project Chief: Southwest Washington Coastal Erosion Study - Research involves understanding complex relationships among sediment supply, littoral processes, and shoreline erosion or accretion in a high-energy coastal environment. Studies encompass multiple time and space scales of coastal evolution, and successfully differentiate natural and anthropogenic influences on coastal change.
Catastrophic Geologic Hazards, Co-Principal Investigator: Tsunami Hazards Study - Research effort to improve our understanding of tsunami hazards through identification and interpretation of sediments deposited from tsunamis
