Antarctic Peninsula Neotectonics and Volcanism ...
Welcome to NBP9507.
In October of 1995, researchers from University of Texas
Institute for Geophysics and Oregon State University began a 44 day
marine geophysical cruise on the R/V N.B. Palmer. The cruise left
from Punta Arenas, Chile. The ship traveled to the Bransfield Strait,
after
an initial SEABEAM 2200 multibeam bathymetry and sidescan sonar survey
of the King George Basin. Ship time was devoted to a variety of
areas of research including "vent sniffing" by Gary Klinkhammer of
OSU. During the cruise a multibeam sidescan sonar survey of
the Bransfield Strait was completed. Time was also devoted to a
multibeam and sidescan sonar survey of the Southwest Scotia Sea in
conjunction with many days of multichannel seismic work. The main goal
of the cruise was to collect 5,000 km of multibeam and sidescan
sonar data to map the structural character and tectonic fabric of
the evolving plate boundary in the southwest Scotia Sea, Shackleton
Ridge,
and Bransfield Strait.
