Inferences into glacimarine sedimentary processes, dynamics, and environments from multibeam sonar records in Alaskan fjords.


Primary objectives:

  1. 1.Quantify sediment flux and inferred denudation rates for several Alaskan fjords.

  2. 2.Investigate glacier retreat seafloor morphology to infer glacial deposition processes and retreat dynamics.

  3. 3.Examine the relationship between glacial retreat and advance on sediment yields.
