Late Quaternary deglaciation and sea-level history of eastern Juan de Fuca Strait, Cascadia

Autor: Antony T. Hewitt, David C. Mosher

Publikováno v: Quaternary International. 121:23-39

Eastern Juan de Fuca Strait of southwestern British Columbia/northwestern Washington State is near the western and southern terminus of Late Wisconsinan glaciation in North America. Seismic-reflection profiles, bathymetric data, sediment core data an

Late Quaternary stratigraphy and seafloor geology of eastern Juan de Fuca Strait, British Columbia and Washington

Autor: David C. Mosher, Antony T. Hewitt

Publikováno v: Marine Geology. 177:295-316

A combination of shallow sediment cores and high-resolution seismic-reflection data were used to identify and map four main surficial geologic units in eastern Juan de Fuca Strait. These units comprise bedrock (unit 1), till/diamict (unit 2), glacial

Ice-rafted debris in the North Pacific and correlation to North Atlantic climatic events

Autor: Darcy McDonald, Antony T. Hewitt, Brian D. Bornhold

Publikováno v: Geophysical Research Letters. 24:3261-3264

A high-resolution record of the flux of ice-rafted debris in deep-sea cores from the Northeast Pacific indicates that the major interstadials that punctuated the last glaciation are concurrent between the North Pacific and the North Atlantic. In the

Applications of Multibeam Backscatter: Using Multibeam Echosounder Backscatter to Characterize and Map Seafloor Features in Shallow and Deep Water

Autor: Antony T. Hewitt, Jerry C Wilson, Richard Salisbury

Publikováno v: All Days.

Abstract Recent developments in multibeam echosounder backscatter processing are now included in most commercially available processing software. These tools allow end users to produce properly corrected backscatter mosaics and add more robust qualit

Integrated Site Investigation of Seafloor Features and Associated Fauna, Shenzi Field, Deepwater Gulf of Mexico

Autor: Nektaria Zois, Antony T. Hewitt, Shawn C. Williamson

Publikováno v: All Days.

Abstract The continental slope of the Deepwater Gulf of Mexico is characterized by complex seafloor topography caused in part by shallow salt deformation. Locally, faults provide pathways for hydrocarbon migration through the suprasalt sediments to t

AUV and ROV Data Integration to Identify Environmentally Sensitive Areas in Deep Water

Autor: Jason Smith, Richard John Weiland, Antony T. Hewitt

Publikováno v: All Days.

Abstract This paper describes a methodology for integrating Autonomous Underwater Vehicle (AUV) geophysical data with Remotely Operated Vehicle (ROV) video in order to predict environmentally sensitive deep-water chemosynthetic habitat. The methodolo
