Purpose
|
|
Map seafloor facies and habitats prior to removal of Elwha River dams.
|
|
|
Information to be Derived
|
|
Surficial geology, bathymetry, grain size, and benthic habitat.
|
|
|
Summary
|
|
4 days spent sonar mapping from 5 to 25 m water depths off the mouth of
|
|
the Elwha river and east. 3 days spent video groundtruthing in area mapped with
|
|
sonar. 1 day spent with bottom macro camera in sandy areas for digital grain
|
|
size analysis, with grab sampling for calibration of digital grain sizing
|
|
program. 5 bad weather days. Sonar bathy and backscatter data, processed in
|
|
the field. Digital video tapes. Digital macro photos. Bottom grab samples.
