Langdon Quetin and Robin Ross, University of California, Santa Barbara. Personnel on Station: Treva Coe, Victoria Hogue. S-014 personnel continued to monitor starvation experiments on E. superba larvae collected during June WinCruise VI, and an individual growth rate experiment on E. frigida sub-adults collected during April cruise. At month-end, these experiments were closed down and surviving individuals were staged, measured, weighed and made ready for CHN and chemical composition analysis. Observations and experiments investigating feeding behaviors of larval E. superba were also continued. Established monoalgal cultures were maintained and new cultures were set up for use in feeding and growth experiments. Data generated from experiments and WinterCruise VI were entered. Starvation tolerance setups and preserved samples from station experiments and WinterCruise VI collections were packed and delivered to logistics for retrograde. Cleanup of Lab 1 and aquarium room was begun in preparation for redeployment. Weekly station and safety meetings were also attended by all S-014 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. Data acquisition software was reloaded into the DA computer on August 01 to restore N-S data streams that had stopped updating several days earlier. On August 02, the bell jar on the vertical seismometer was reseated to seal a slow vacuum leak. 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. On August 06, Narrow band data acquisition inexplicably failed to start, but the next day all operations returned to normal. The Kinemetrics clock was intermittently unlocked from August 11 through August 12. 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 austral-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. On two occasions throughout the month, the air sampling intake stack became plugged with snow. The plugs were removed, and in one case a contaminated filter was replaced, after which time the system operated normally. 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 position of the R/V Nathaniel B. Palmer, up to the conclusion of the AnzFlux cruise. Additionally, SSM/I ice concentration contour maps were faxed to the R/V Polar Duke to assist in navigation through heavy ice while en route to Palmer Station. IR images and ice concentration contour maps of the R/V Polar Duke's position were also sent to Marine Operations at ASAHQ. 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. Absolute calibrations were performed on August 15 and on August 29. High voltage levels were adjusted to account for increasing brightness, and data scans were added at 1100Z, 1200Z, 2000Z, 2100Z, and 2200Z. 01020740.764 PLM013.SEP
