Dr. Mahlon c. Kennicutt, II, P.I., Geochemical and Environmental Research Group, Texas A&M University Field Team: S.McDonald, K.Foster-Springer and E.Haubold The personnel from S-041 currently at Palmer Station are Susanne McDonald, Kate Foster-Springer and Elsa Haubold. Fishing operations were conducted from the Polar Duke on March 23 at Low Island and Dallmann Bay. Approximately 300 fish were captured by trawling. The fish were transferred from the Polar Duke to sea water tanks at Palmer Station for subsequent experiments. Two experiments to assess the effects of polynuclear aromatic hydrocarbons (PAH) on antarctic fish are in progress. One set of fish was injected with diesel fuel; whereas, the other set was injected with benzo[a]pyrene. Liver, muscle and bile are collected from fish sacrificed at specific intervals. Liver and muscle tissue will be analyzed for PAH concentrations. Bile will be analyzed for PAH metabolite concentrations. Additionally, a microsomal subcellular fraction is being prepared from liver tissues to determine cytochrome P-450 content, aryl hydrocarbon hydroxylase activity and ethoxyresorufin o-deethylase (EROD) activity. Fish traps have also been deployed around the Bahia Paraiso wreck and Palmer Station. Tissues will be collected and analyzed as described above. S-106 VLF TRIMPI STUDIES AT PALMER STATION. U.S. Inan (P.I.), No personnel on station. Equipment being monitored and maintained by ASA science technician Rod Corson. All recordings were made for the month of March. Inventory of data now on station: (March 31, 1992) 200 - Continuous VLF Tapes from 28 Dec to present. 107 - Trimpi recordings on digital tape from 21 Dec. to present. All data tapes have been crated and will be shipped North on 12 April, with the next departure of R/V POLAR DUKE. On 06 March, Continuous VLF, daily recording schedual was changed to 0000 to 0300 and from 0700 to 1000 UT. One digital tape recording of Trimpi activity is also recorded daily from 0130 to 1200 UT. Monday morning charts of the Trimpi data are still being sent to Stanford so that the investigators can maintain a better understanding of equipment performance and suggest any needed changes or adjustments to the site. Support poles for RF cable, going to loop antenna, were reerected on 19 March. Received 15 crates containing equipment and supplies for upcoming site visit. S-254 CHLORINE - AND BROMINE - CONTAINING GASES IN THE ANTARCTIC. R.A.Rasmussen, P.I., Oregon state University. No personnel on station, project being monitored and maintained by station physician. A total of 14 clean air samples have been archived for retrograde for S-254. There are currently 84 empty canisters on station. The Station Physician was not able to take air samples for the week of March 22. The glass connector to the sampler broke and the spare parts were not found until the proper wind conditions were lost. S-257 GEOPHYSICAL MONITORING FOR CLIMATE CONTROL (GMCC). J.T. Peterson and L.Waterman, P.I.'s, NOAA No personnel on station, project being monitored and maintained by station physician. A total of 12 air samples have been archived for retrograde for S-257. There are currently 108 empty canisters on station. S-275 UM/DOE ATMOSPHERIC MONITORING PROGRAM AT PALMER STATION. T. Snowdon of University of Miami and C.Sanderson/N.Chui, EML/DOE N.Y., P.I.'s No personnel on station. System being run by ASA science technician Rod Corson. System continues to operate with normal weekly schedule of calibration, background, and sample counts, with one sample filter being exposed for the duration of the week. All recorded data on station will be shipped North with the departure of the R/V POLAR DUKE on 12 April. Information on 3.5 floppies will be copied and stored on site before the originals are shipped. On Station there are currently six (6) exposed filters, one (1) filter being exposed, one (1) prepared blank filter, two (2) archive disks for months of February and March, and one (1) data disk currently being used to log data. T-312 TERASCAN SATELLITE IMAGING SYSTEM. R. Whritner, Scripps Institution of Oceanography, La Jolla, California No personnel on station. System being run by ASA science technician Rod Corson The satellite collection schedule continues with three (3) NOAA satellite passes. Two (2) DMSP f-10 satellite passes are also collected daily. These passes are recorded digitally on 8mm video tape. There are tweleve (12) full 8mm "video" tapes of collected passes on station and one current tape almost complete. A few passes have failed in the collection process for various reasons and Palmer is in contact with Bob Whritner and Seaspace about these irregularities. The lost passes amount to only a very small percentage of total desired passes. T-313 UV MONITORING EXPERIMENT. C.Booth, Biospherical Instruments. No personnel on station. System being run by ASA science technician Rod Corson. The scan schedule continues with hourly data scans, plus three response and two wavelength scans per day. Daily data packages are sent to Biospherical via E-Mail. The Palmer monthly weather summaries are now being sent to Biospherical on what we expect to be a regular basis.
