Langdon Quetin and Robin Ross, University of California, Santa Barbara. Personnel on Station: Carol Wyatt, Kristin Balalis, Victoria Hogue During the month of May, personnel continued to monitor and maintain starvation experiments on both E. superba and E. frigida krill caught during the April collection cruise. One starvation experiment was taken down upon reaching 75% mortality and remaining larvae were staged, measured and placed in CHN boats for later analysis at U.C. Santa Barbara. Two individual growth rate experiments were set up using remaining E. frigida. The same protocol was used for both experiments with the exception of jar placement. The first experiment was placed on a roller stirrer system, and the second experiment was placed on the bench top to determine any effect the roller stirrer may have on animal health. Daily maintenance of the experiments consisted of monitoring animal behavior & general health, food consumption, and maintaining predetermined food level in each jar. Food levels and culture Chl a levels were determined using an acetone extraction and fluorometry reading method. Weekly water changes were also performed on each of the starvation and growth experiments. Established algal monocultures were maintained and new cultures set up for continued feeding of krill growth experiments using healthy cultures. Pre-cruise packing for WCVI was also initiated. Weekly station and safety meetings were 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. A station-wide power outage for testing of power plant equipment was scheduled on 14 May to coincide with a data tape change in order to conserve a low supply of blank tapes. Recording was stopped, and the DP was shut down prior to the outage and then restarted with a new tape when power was restored. More tapes are expected to arrive on 14 June. 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. Narrowband data collection was shifted from 0000-1200UT to 1000-2400UT for ten days around 10 May in order to coincide with the occurrence of an annular eclipse in the northern hemisphere on that date. The broadband data collection schedule remained unchanged. The UPS successfully weathered a scheduled power outage on 14 May, so the only data lost were from the 20 minutes of the outage itself. 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 sampling pump was off for 20 minutes on 14 May due to a scheduled power outage. 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. DSMP 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. Several ice images were produced and sent to Marine Operations at ASAHQ. Investigation into the feasibility of providing ice concentration maps of the same areas from DMSP SSM/I data was begun. Several test maps were prepared and sent to Marine Ops. T-313 UV MONITORING EXPERIMENT. C. Booth, Biospherical Instruments, Inc. No personnel were on station A defective heater thermostat in the UV addition that had a penchant to stick on was replaced. A power outage on 14 May was scheduled so that no scans were missed. An absolute calibration was performed with the seasoned lamp on 19 May. 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 were produced in support of Science. 02040836.388 PLM069.JUN
