Principal Investigators: Langdon B. Quetin and Robin M. Ross, University of California at Santa Barbara. Field Team: T. Frazer, C. Wyatt and J. Mahoney During July, we initiated laboratory experiments to measure growth rates and isotopic turnover in larval krill under controlled temperature and food regimes. Larvae used in the experiments are monitored daily and the number of molts recorded. Preliminary observations suggest clear differences in growth rates and intermolt periods due to both variables. A subsample of each experimental population is removed weekly and individual animals staged, measured and weighed prior to preparation for isotopic analyses. Oxygen consumption experiments were also completed with larvae maintained under different temperature and food regimes to compliment field data collected during the previous month (Win Cruise V). Preliminary work in preparation for ice-feeding experiments (scheduled for August) continues. Phytoplankton cultures are being maintained for ongoing feeding experiments and krill collected during cruises earlier in the season are opportunistically analyzed for lipid and protein content. Additional samples collected during Win Cruise V have also been analyzed, e.g., chlorophyll's, and or prepared for subsequent work either at Palmer Station or UCSB. We thank the winter-over personnel at Palmer Station for their continued support and contributions to our project. S-106 Stanford VLF. U. Inan, Stanford University. Digital Data Acquisition system is operational. Daily data continues to be collected and prepared for retrograde. System being operated by ASA science technician, Andrew Archer. S-275 UM/DOE Atmospheric Monitoring Program at Palmer Station. T. Snowdon, University of Miami; C. Sanderson/N. Chui, EML/DOE N.Y. No personnel on station. System being run by ASA science technician. System continues to operate on a normal weekly schedule of calibration, background, and sample counts, with one sample filter being exposed for the duration of the week. T-312 Terascan satellite imaging system. R. Whritner, Scripps Institute. No personnel on station. System is being operated by station science technician. Telemetry equipment has been failing, resulting in shortened pass collection. Secondary terminal is non-operational as is graphics capability. Regular collection of both DMSP and NOAA satellite telemetry continues to capacity. T-313 UV Monitoring Experiment. C. Booth, Biospherical Instruments. No personnel on station. System is being operated by station science technician. The system is successfully collecting UV data. A problem occurred in the power supply directly affecting the response calibration scans. The problem was due to a failure found in the power strip supporting the power supply. S-091 Seismic Observatory, United States Geological Survey. No personnel on station. System is being monitored by station science technician. Data is successfully collected and prepared for retrograde. Laser printer, hardware connections and downloading of system sensitivity software was accomplished. Frazer/NESS 01234514.263 PLM039.AUG
