Notes
|
|
(from USGS Bulletin 1/13/95)
|
|
John Haines (BAMG) and Guy Gelfenbaum (BUSGS), both at the Center for
|
|
Coastal Geology and Regional Marine Studies in St. Petersburg, Florida, and
|
|
John Dingler (BUSGS) in Menlo Park, Calif., recently completed an intensive
|
|
stint at Duck, North Carolina, as part of the DUCK94 Nearshore Field
|
|
Experiment. This major experiment was hosted by the U.S. Army Corps of
|
|
Engineers Field Research Facility (FRF) and was jointly sponsored by the
|
|
Corps of Engineers, the Office of Naval Research, and the USGS. Abby
|
|
Sallenger represented the USGS on the interagency organizing committee.
|
|
DUCK94 was the first phase of a two part effort to advance our fundamental
|
|
understanding of sediment transport in the nearshore zone through
|
|
integrated field measurements and numerical modeling. The second phase,
|
|
SANDYDUCK, is scheduled for October 1997.
|
|
|
|
DUCK94 was a series of independently developed investigations, by
|
|
researchers from 12 universities and 4 government agencies, that were
|
|
integrated into one large experiment. The scientific efforts in DUCK94 by
|
|
the USGS included a study of the spatial distribution of bottom roughness
|
|
as measured by side-scan sonar (Dingler), and a study of the relative
|
|
contributions from mean currents and waves to the vertical structure of
|
|
turbulence stress (Haines and Gelfenbaum). The turbulence measurements were
|
|
made using an array of newly developed acoustic doppler current meters and
|
|
resulted in nearly 300 mbytes of data daily. Both data sets are unique and
|
|
will be critical to understanding sediment transport processes in the
|
|
nearshore environment and ultimately help us to better predict coastal
|
|
erosion. The large scale of the experiments required support from numerous
|
|
people, including Terry Kelley, Larry Kooker, Keith Ludwig, Mark Kennedy,
|
|
Rob Wertz, Bill Townsley, Scott Pendygraft, and Dan Penrod. Many thanks to
|
|
all.
