Many thanks to the officers and crew of the R.V.I.B.
Nathaniel B. Palmer and to the Raytheon Polar Services
Technicians for their assistance during the cruise. Thanks
also to J. Warren, A. Girard, M. Taylor, K. Fisher,
M. Dennett, and M. Butler for their hard work at sea.
R. Eastwood, S. Tiwari, and Q. Hu assisted in developing
or implementing the image extraction and identification
routines used in the analysis. C. Ribic, E. Chapman,
F. Stewart, and K. Claffey conducted ice-cover observations
during the cruise and kindly shared their data with us.
E. Hoffman and J. Klinck generously shared their CTD
dynamic height topography. S. Howard collected and
processed the ADCP data; we thank her and L. Padman
for sharing these data. R. Beardsley and C. Moffat advised
us regarding correction of ADCP velocities for tides and
near-inertial currents. We thank all our colleagues in the
Southern Ocean GLOBEC program for their support. Two
anonymous reviewers provided comments and suggestions
that greatly strengthened this manuscript. This research
was supported by National Science Foundation Grant
OPP-9910307 to P. Wiebe, C. Ashjian, C. Davis, and
S. Gallager. This is GLOBEC contribution number 529.
