Record #196262:

Multibeam bathymetry, terrestrial LiDAR topography, and three-dimensional velocity structure observations of the ice marginal marine environment at Hubbard Glacier, AK / David Finnegan, and 4 others.

Title: Multibeam bathymetry, terrestrial LiDAR topography, and three-dimensional velocity structure observations of the ice marginal marine environment at Hubbard Glacier, AK / David Finnegan, and 4 others.
Author(s): Finnegan, David.
Date: 2011.
In: ERDC Technical Report. (2011.), TR-10-8 (2011)
Abstract: Reports survey of submarine and terrestrial environment of Hubbard Glacier tidewater terminus and area surrounding Gilbert point. Combines high-resolution, multibeam bathymetry and acoustic Doppler current velocity profiles with simultaneously acquired high-resolution LiDAR topography to examine section of glacier where ice damming of Russell Fiord may occur (as twice since 1986), and to characterize sediment accumulations and seabed morphologies related to glacier advance/retreat. Discusses data acquisition and processing, including GPS corrections for tides. Interprets results, noting strong tidal currents, and coarse or hard/overconsolidated channel bed on which moraines created by seasonal ice front advance are not well preserved. Recommends studies in early May, before ice advance reduces gap width.
