Langdon Quetin and Robin Ross, University of California, Santa Barbara. Personnel on Station: Treva Coe, Victoria Hogue. S-014 personnel set up and monitored three starvation experiments on E. superba larvae collected during June WinCruise VI; continued to monitor an individual growth rate experiment on E. frigida krill collected during April cruise; and began investigating feeding behaviors of larval E. superba. Established monoalgal monocultures were maintained and new cultures were set up for use in feeding and growth experiments. Winter Cruise VI ended July 4 with arrival of Polar Duke on station. Offloading of experiments, collected E. superba larvae, cruise supplies and wintering personnel were completed by July 6 departure. Weekly station and safety meetings were attended by all S-014 station personnel. S-091 PALMER IRIS SEISMOLOGY. R. Butler/G. Holcomb, U.S. Geological Survey, Albuquerque, NM No personnel were on station. The system has been monitored by the station science technician. The seismic station successfully recovered from three power outages that occurred throughout the month. On July 08, the E-W data streams abruptly disappeared and did not reappear until software programs were reloaded into the Data Acquisition computer on july 13. On July 24, the vertical mass position was found stuck at the limit of its range. The vacuum, found bad, was pumped back down, and the mass position was adjusted by motor control to bring the instrument back into operating range. On July 29, the N-S data streams stopped updating. S-106 VERY LOW FREQUENCY (VLF) REMOTE SENSING OF THUNDERSTORM AND RADIATION BELT COUPLING TO THE IONOSPHERE. U. Inan, Stanford University. No personnel were on station. The system has been operated by the station science technician. Several hours of data collection were lost due to the three power outages that occurred during the month. Recently, the GOES satellite, used by the Kinemetrics clock that keeps time for the VLF experiment, suffered system problems. On July 21, it was noticed that the Kinemetrics clock would intermittently lose its satellite lock. On July 27, the clock lost and was unable to regain a satellite lock. Data collection continued, although critical timing was often absent. S-254 CHLORINE- AND BROMINE-CONTAINING TRACE GASES IN ANTARCTICA. R.A. Rasmussen, Oregon Graduate Institute for Science and Technology. There are no personnel on station. Air samples are taken on a weekly basis by the station physician. The samples are returned to the Institute for analysis of a number of trace components, especially chlorine- and bromine-containing gases. These elements have been implicated in the chemical processes that contribute to the astral-spring depletion of the ozone layer over Antarctica. This work will contribute to a better understanding of the buildup of trace constituents, particularly those of high-latitude marine origin. S-257 SOUTH POLE MONITORING FOR CLIMATE CHANGE. James T. Peterson, Palmer Station, Environmental Research Laboratories, National Oceanic and Atmospheric Administration. There are no personnel on station. Air samples are taken on a weekly basis by the station physician. The National Oceanic and Atmospheric Administration (NOAA) Climate Monitoring and Diagnostics Laboratory team continue long-term measurements of trace atmospheric constituents that influence climate. The Palmer Station air samples are returned to the NOAA laboratory for analysis of trace constituents, including carbon dioxide. These measurements are part of NOAA's effort to determine and assess the long-term buildup of global pollutants in the atmosphere. These data will be used to determine how the rate of change of these parameters affects climate, particularly by including them in climate model studies. S-275 UM/DOE-EML REMOTE ATMOSPHERIC MEASUREMENTS PROGRAM. J. Prospero/T. Snowdon, University of Miami; C. Sanderson/N. Chui, EML/DOE N.Y. No personnel were on station. The system has been operated by the station science technician. One sample filter was exposed for the duration of each week, and a weekly schedule of calibration, background, and sample counts was maintained. The air sampling pump was off for about fifteen minutes during the power outage on July 09, and for a total of four hours and fifteen minutes during the two outages on July 22. T-312 TERASCAN SATELLITE IMAGING SYSTEM. R. Whritner, Scripps Institute of Oceanography, La Jolla, CA. No personnel were on station. The system has been operated by the station science technician. DMSP and NOAA telemetry were collected, processed, and archived. DMSP infrared telemetry was examined on a daily basis for clear conditions in the AnzFlux area and along the ice edge in the northern Weddell Sea. Additionally, DMSP SSM/I data were processed to provide ice concentration contour maps. Ice images and ice concentration contour maps were produced and sent to Marine Operations at ASAHQ in support of the AnzFlux cruise. Five of fifteen scheduled scans were lost during the four hour unplanned power outage on July 22. T-313 UV MONITORING EXPERIMENT. C. Booth, Biospherical Instruments, Inc. No personnel were on station The system has been operated by the science technician. Throughout the month, raw irradiance data were collected daily and transmitted to BSI, and preliminary irradiance data were produced in support of Science. An absolute calibration was performed on July 16 with the seasoned lamp. No scans were lost during the three unplanned power outages that occurred during the month. 01155644.263 PLM042.AUG
