R/V NATHANIEL B. PALMER WEEKLY REPORT FOR THE PERIOD 07-13 OCT 1996 A. MANAGEMENT Significant Activities: The ship arrived at the ice edge October 8. There the first test station was conducted. Two CTDs, one Trace Metal CTD and a In-situ (Thorium pumps) cast were successfully completed. Also, upon arrival at the ice edge, the Seismic Gun Winch, the Moss Landing van, Thorium van, convertible van and Kevlar Winch were repositioned and secured. The convertible mooring van and seismic winch were welded to the deck as requested by the Captain. The mooring floats in the convertible van were unloaded, inspected for damage (no damage found) and were reloaded. On October 11 there was a third (successful) CTD cast, the Kevlar was respooled with a 250lb weight on it, after which four thirty liter bottle for the Moss Landing trace metal group were washed and tested from the aft Kevlar winch. In addition to supporting all of the above activities, the Marine Techs accomplished the following: The stainless steel shieve on the Waterfall Winch was bead blasted to remove all rust. The Hydrolab Ice maker was repaired and is currently up and running. After the CTD was terminated we put the Chinese Fingers on the CTD cable. The Kevlar cable on the Waterfall Winch was Terminated. Many other minor jobs were looked after during the week, but the majority of the Marine Tech's, Electronics Tech and science parties time has been spent dealing with getting the helo-deck closed-loop incubation system up and running, and keeping it running. Despite some setbacks, they were successful. For the Electronic Tech, the first part of the week consisted mostly of repairing damage caused by the storm. A computer system and a winch readout box were serviced from the Moss Landing Van. Most of the damaged components were returned to service. Power was restored to all vans and water damage to the ML vans' wall outlets was repaired. The Power cable to the ML winch was respliced and a replacement start switch was installed, a box for mounting the switch was constructed by the MTs. The incubator heater system had several problems. On Friday the engine room reported a ground fault error, it was traced to the heater. The problem was remedied and the heater began to function properly without causing a ground fault. The temperature probe, however, was not working. Both contacts of the temp probe were found to be grounded, the output was not changing. A manual system for adjusting the heater was installed using a voltage calibrator. Additionally, a new procedure for resetting the Ashtech was written; the trace metal rosette was terminated and cast; a cable was run from the wetlab to the helo deck for a GPS Antenna; a patch cable to improve the monitor reception on the CCTV system was fabricated and installed. Logging of underway seawater instruments came to a halt after the clutch in the small monopump failed. Air filters were cleaned in the drylab and some printing tests were conducted on the Bathy. Science mast sensors were checked and cleaned. The Ashtech performed well, so plans to replace the remanining antennas have been put on hold. The EMT provided patient care in instances both requiring and not requiring MAS support involving illness, no injuries. The Labratory Supervisors provided support to the following science projects during the second week of the JGOFS Process 1 Cruise (NBP96-4A): S-209/210/211/256/258, S-218, S-219, S-223/255, S-236, S-238/239, S-240/241/224, S-244, S-250, S-251, and S-253. Direct support was provided in setting up instruments and equipment, completing a Test Station cast with the new Trace Metal-clean CTD Rosette, checking the operation of the Helo Deck incubator system and other equipment on deck, and rearranging the Helo Hangar to facilitate access to grantee materials and packaging materials/drums for hazardous wastes. A second fluorometer with matching filter sets was set up in order to perform a cross-calibration and intercomparison of the performance of two fluorometers. Both instruments were found to perform equally well, verifying their E/R/R at the vendor. Considerable effort by the lab supervisors resulted in a complete updated review of JGOFS Process 2 SIP Section 7 (Materials and Supplies to Purchase). Efforts continued towards updating the lab equipment/instruments master spreadsheet file, updating inventories, as well as assembling an NBP Lab Supervisor manual to direct lab support and waste handling efforts. Also accomplished were several small projects, including installation of a room darkening curtain for a epifluorescence microscope in the aft portion of the Computer Lab and installation of a UPS for the autosalinometers in the Auto Sal Room. Fabrication of an ultraviolet transparent (UV-T) plexiglass incubator for S-239 was begun late in the week and expected to be completed early next week. The Lab Supervisors worked with the Electronics Technician and Senior Marine Technician to maintain the TSG while the vessel transited pack ice enroute to the study area. For the majority of the week seawater to the TSG was shut-down because of clogging of the TSG plumbing with sea ice and snow. Flow of seawater to the TSG will be restarted after arrival in a suitable lead/polynya area. The IS accomplished the following: Performed routine backups on Novell, Macintosh, and Unix servers; Processed Email via 56K and SLIP connections. Traced several email problems for a small group of users; Assisted science team with PC, Macintosh and email questions. Set up several new Xircom/laptop connections for science party. Downloaded and printed ice imagery; Performed RT-DAS operations: setup for O2 sensor, which included identification of 6 marginal/defective short-haul modems out of the ship's stock of 8. Replacements for short-haul modems and appropriate cabling will be requested under separate cover; Ran geophysical processing (pmag, pgrav, pbath, xmerge, and JGOFS formatting routines) for NBP9604A data; Generated plots of JGOFS/RT-DAS data; Wrote a QBASIC program to re-format Beckman LS-3801 capture data to fit science party's Excel spreadsheets; Generated scripts to plot various MET, OXY channel data fields vs. time. Planned Activity: The NBP will continue its transit to Stations Sei (74S, 171E) and Orca (76.5S, 178W) in the Ross Sea in support of the JGOFS Process I Cruise (NBP96-4A) ending at the ice edge off McMurdo Station about 7 November. B. PERSONNEL The ship deployed with 7 ASA and 32 science personnel embarked, including Dr. Walker O. Smith, Jr., as Chief Scientist. C. RESEARCH VESSEL OPERATIONS Ship Schedule: 7-13 October 1996: Underway in support of NBP96-4A. Charter Issues: Continued excellent support from Edison Chouest Offshore. Email/INMARSAT traffic information is currently not available. Regards, James Orzech, Marine Project Coordinator
