Working with Kristen Buck

Working with Emily Eidam (Coastal & Fluvial Sediment Dynamics)

I study coastal sediment dynamics and the resilience of estuaries, deltas, and other low-lying coastal environments, particularly in the face of relative sea-level rise.

Specialty

Founding Program Director for the undergraduate Oceanography degree.
Students interested in this major should contact one of the CEOAS undergraduate advisors.

Current Research

Land - ocean connectivity from event to millennial time scales. Sediment and carbon fluxes from small, mountainous rivers. Stratigraphic fidelity. Estuarine and continental margin sedimentation in the Pacific Northwest and elsewhere. Carbon burial in Oregon estuaries. Seafloor properties & bioturbation.
