Sediment accumulation in a manipulated bay of Puget Sound, Bellingham, WA.
Mud Bay, located in Bellingham, Washington at the north end of Chuckanut Bay, is filling with sediment at a rate greater than projected sea-level rise. This is worrisome as the bay is an important habitat for eelgrass meadows, shellfish beds, and birds. Also, Chuckanut Creek, the primary fluvial input into the bay, has ...
Sediment characteristics at the delta of Chuckanut Creek, Mud Bay, Bellingham, Washington
ud Bay is south of Bellingham, WA, in the northern portion of Chuckanut Bay. It is predicted to be inundated by tsunamis generated by large Cascadia earthquakes. In this report, I describe shallow sediments in the bay and at the delta where Chuckanut Creek enters the bay. I also describe shoreline changes recorded by historic ...
Geomorphic Reconstruction of Alki Point in West Seattle Based on Chronostratigraphic Relationships of Mid-Late Holocene-Aged Intertidal Deposits
A tombolo may have tied a bedrock knoll at the western tip of Alki Point to the mainland before a large magnitude 7 or greater earthquake ruptured within the Seattle fault zone, resulting in ~23 ft of uplift at Alki Point and exposing shallow beach/intertidal deposits. The purpose of this study was to (1) reconstruct the ...
