Purpose
|
Drilling borings (6-10) up to 70 m deep to collect sediment cores for
stratigraphy, porewater salinity, 14C, etc. This is Phase II of a similar
effort in spring 2002. NC Geological Survey (Bill Hoffman) is the lead on the
drilling; Ron Thieler is USGS project chief.

Summary
|
U.S. Geological Survey (USGS) scientists from Woods Hole, MA, and their
collaborators landed on the beaches of North Carolina in April to implement two
more pieces of ongoing efforts to understand the evolution and modern dynamics
of the State s extensive barrier-island system, including its hydrogeology.
Stormy conditions provided the perfect weather for shoreline-erosion studies
conduced by Jeff List, Peter Ruggiero, and collaborator Bill Birkemeier of the
U.S. Army Corps of Engineers Field Research Facility at Duck, NC. John Bratton
and other scientists working with a contract drilling crew were less
enthusiastic about the storm, which slowed (and even stopped for 1 day) their
subsurface sampling efforts on the islands. The rotosonic-drilling team
recovered almost 900 ft of sediment cores from six sites, including one mainland
site, and measured the salinity of 130 pore-water samples. Beth Wrege and other
USGS scientists from offices in North Carolina and Reston, VA, conducted gamma
logging of each hole and installed monitoring wells at several sites. Other
participants in the drilling program included Bill Hoffman and Bob Brooks (North
Carolina Geological Survey); Reide Corbett, Lance Tully, and Irene Abbene (East
Carolina University); and an excellent drilling crew from Boart Longyear.
Additional chemical analyses are being performed on pore-water samples at East
Carolina University. Rob Thieler (USGS, Woods Hole) is organizing a workshop
scheduled for June to study and sample the split sediment cores, which are
stored at the North Carolina Geological Survey s Coastal Plain Office in
Raleigh.
