Palmer Lter Contribution No.33

From 23 August to 30 September 1993, a multidisciplinary
cruise was conducted aboard the RV Polar Duke as part of the
Palmer Long-Term Ecological Research (LTER) program off the
Antarctic Peninsula.  Stations were occupied at specified grid
locations (Figure 1) within the Palmer LTER survey grid (Waters
and Smith, 1992).  The cruise departed and returned to Punta
Arenas,Chile.
 Oceanographic data were collected using a Bio-Optical Profiling
System (BOPS) (for a complete description see Smith et al., 1984
and Smith and Baker, 1984).  The BOPS package was configured with
a SeaBird CTD sensor to measure temperature, conductivity, and
pressure; a BioSpherical PAR and spectral irradiance sensor; and
a SeaTech fluorometer.  The first portion of this report presents 
the hydrographic data collected with the CTD system on the BOPS.
The following measured and derived quantities are reported:
temperature, potential temperature, salinity, density, dynamic
height, and Brunt-Vaisala frequency.
 Upon return from the cruise, the CTD measurements from the BOPS
were processed initially at the Center for Remote Sensing and
Environmental Optics at the University of California, Santa Barbara.
Final processing and report generation were compsleted at the Center
for Coastal Physical Oceanography (CCPO) at Old Dominion University.
 This report also contains temperature data collected using a 
Sippican, Inc. MK-12 expendable bathythermograph (XBT) system.  Upon
return from the cruise, the XBT data were processed by LTER personnel at
CCPO.
