Identifying the Greatest Earthquakes of the Past 2000 Years at the Nehalem River Estuary, Northern Oregon Coast, USA

Autor: Alan R. Nelson, Andrea D. Hawkes, Yuki Sawai, Simon E. Engelhart, Rob Witter, Wendy C. Grant-Walter, Lee-Ann Bradley, Tina Dura, Niamh Cahill, Ben Horton

Publikováno v: Open Quaternary, Vol 6, Iss 1 (2020)

We infer a history of three great megathrust earthquakes during the past 2000 years at the Nehalem River estuary based on the lateral extent of sharp (≤3 mm) peat-mud stratigraphic contacts in cores and outcrops, coseismic subsidence as interpreted

Investigating Controls on Barrier Island Overwash and Evolution during Extreme Storms

Autor: Jesse N. Beckman, Joseph W. Long, Andrea D. Hawkes, Lynn A. Leonard, Eman Ghoneim

Publikováno v: Water, Vol 13, Iss 20, p 2829 (2021)

Over short periods of time, extreme storms can significantly alter barrier island morphology, increasing the vulnerability of coastal habitats and communities relative to future storms. These impacts are complex and the result of interactions between

An Automated Model to Classify Barrier Island Geomorphology Using Lidar Data and Change Analysis (1998–2014)

Autor: Joanne N. Halls, Maria A. Frishman, Andrea D. Hawkes

Publikováno v: Remote Sensing, Vol 10, Iss 7, p 1109 (2018)

Previous research has documented the usefulness of Lidar data to derive a variety of topographic products (e.g., DEM, DTM, canopy and forest structure, and urban infrastructure). Lidar has been used to map coastal environments and geomorphology; howe

Minimal stratigraphic evidence for coseismic coastal subsidence during 2000 yr of megathrust earthquakes at the central Cascadia subduction zone

Autor: Yuki Sawai, R. C. Witter, Benjamin P. Horton, Lee-Ann Bradley, Alan R. Nelson, Niamh Cahill, Andrea D. Hawkes

Publikováno v: Geosphere. 17:171-200

Lithology and microfossil biostratigraphy beneath the marshes of a central Oregon estuary limit geophysical models of Cascadia megathrust rupture during successive earthquakes by ruling out >0.5 m of coseismic coastal subsidence for the past 2000 yr.

Hurricane Michael (2018) was the first Category 5 storm on record to make landfall on the Florida panhandle since at least 1851 CE (Common Era), and it resulted in the loss of 59 lives and $25 billion in damages across the southeastern U.S. This even

Diatoms of the intertidal environments of Willapa Bay, Washington, USA as a sea-level indicator

Autor: Simon E. Engelhart, Jason S. Padgett, Andrea D. Hawkes, Isabel Hong, Tina Dura, Benjamin P. Horton, Robert J. O'Donnell

Publikováno v: Marine micropaleontology, 2021, Vol.167, pp.102033 [Peer Reviewed Journal]

An understanding of the modern relationship between diatom species and elevation is a prerequisite for using fossil diatoms to reconstruct relative sea level (RSL). We described modern diatom distributions from seven transects covering unvegetated su

Several processes contributing to coastal relative sea-level (RSL) change in the North Atlantic Ocean are observed and/or predicted to have distinctive spatial expressions that vary by latitude. To expand the latitudinal range of RSL records spanning
