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.
