Langdon Quetin and Robin Ross, University of California, Santa Barbara Personnel on station: Carol Wyatt, Johana Squier, Kristin Balalis, Victoria Hogue Three new members of S-014 arrived at Palmer Station on April 6, 1994. Two days were spent preparing for the collection cruise and setting up the lab in preparation for post-cruise experiments. Three members of S-014 and one member of S-028 joined the 10 day collection cruise on the R/V Polar Duke from 9 April to 19 April 1994. One member of S-014 was left on station during that time to learn phytoplankton gardening techniques for upcoming experiments. During the collection cruise, four days were spent trawling in the Gerlache Strait and the remaining six days were spent trawling between Palmer Station and Adelaide Island. A total of 217 trawls were made with approximately 500 various stage larval krill (E. superba) collected. Upon returning to Palmer Station, all live animals were sorted and staged. A starvation experiment was set up using the healthy calpytopis 2 larvae, and the remainder of the larval krill were used for condition factors. A starvation experiment with E. frigida was also set up using the frigida sub- adults collected on the cruise. One member of S-014 departed on the R/V Polar Duke for Punta Arenas on 28 April 1994 leaving three members on station. S-028 LONG-TERM ECOLOGICAL RESEARCH (LTER) ON THE ANTARCTIC MARINE ECOSYSTEM: AN ICE-DOMINATED ENVIRONMENT (PREY COMPONENT). Robin Ross and Langdon Quetin, University of California, Santa Barbara. Personnel on station: Karen Haberman, Truc Nguyen Grazing rate experiments for Euphausia superba adults continued through the first week in April. Primary sample processing was completed, including all fluorometry and HPLC analysis. Counting of frozen slide samples was begun using the epifluorescent microscope. Calibrations were performed on both the fluorometer and HPLC used for these experiments. Data entry for the Palmer 93-94 season was completed. Phytoplankton cultures were maintained, and phytoplankton care techniques were taught to S-014 personnel, who will maintain these cultures through the winter. One of our personnel also assisted S-014 during their 10 day collection cruise on the R/V POLAR DUKE. All preserved samples were retrograded to CONUS, and equipment was packed and stored on site for use next season. Frozen samples were transported onto the R/V POLAR DUKE for hand-carry transport to CONUS. Personnel departed on the R/V POLAR DUKE on April 28. 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. An autoload of the DA computer on 5 April effectively returned the north-south data streams but also inexplicably advanced the system clock by approximately five hours and 20 minutes. Cycling power on the GPS clock unit failed to restore correct timing. A repeat of the autoload procedure on 9 April returned the clock to the appropriate time, and therefore the system to normal operations. S-106 VERY LOW FREQUENCY (VLF) REMOTE SENSING OF THUNDERSTORM AND RADIATION BELT COUPLING TO THE IONOSPHERE. U. Inan, Stanford University. Steve Reising was on station from 6 April to 28 April. A new section of cable was run through the backyard to replace an old lower section that had been spliced in several places. The guy wires supporting the antenna tower were retensioned. Two new posts were placed in the glacier to support the antenna loops, and all loop to post connections were adjusted for appropriate loop geometry. Many calibrations were executed before and after cable and antenna maintenance. Noise measurements were taken with a portable VLF system at the current antenna site and at Old Palmer. Many connections and system settings in the VLF hut were checked and, as necessary, adjusted. 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. 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. A meeting was held with the MPC for the upcoming ANZFLUX cruise to discuss ice imaging support. Meetings were also held with ASA communications engineers to discuss issues relating to the SODAS upgrade. T-313 UV MONITORING EXPERIMENT. C. Booth, Biospherical Instruments, Inc. No personnel were on station A 5.25 inch floppy drive was received and installed in the data processing computer to replace a defective drive. An absolute calibration was performed with the site standard lamp on 26 April. High voltage levels and the scan schedule were adjusted in response to the darkening sky conditions. Throughout the month, raw irradiance data were collected daily and transmitted to ATSVAX for BSI, and preliminary irradiance data and inferred ozone abundances were produced in support of Science. 03182833.138 PLM137.MAY
