HAWAII OCEAN TIME-SERIES KM0314 General Cruise Plan COOK-BOOK Transect II VESSEL: R/V Kilo Moana, University of Hawaii MASTER OF THE VESSEL: Captain Gray Drewry CHIEF SCIENTIST: Karin Björkman, University of Hawaii STAG Technician: Kuhio Vellalos STAG Electronics Technician: Tim McGovern Load: September 29, 2003, 1200 AST Departure: September 30, 2003; 1330 AST Arrival: October 10, 2003; 0730 HST 1.0 SCIENTIFIC OBJECTIVES The objective of this cruise is the collection of hydrographic and biogeochemical data along the transect from Kodiak, AK to Oahu, HI. We plan to occupy approximately 22 stations enroute to Oahu with higher resolution sampling across the transitional zone between the northern North Pacific gyre boundary and sub-Arctic waters approximately located between 35'N-45'N. 1.1 SCIENTIFIC OPERATIONS Station Activities Station 1-22 CTD/FRRF operations (0-250m) Underway/continuous Thermosalinograph, fluorometry Mapping XBT, XCTD FRRF (hooked up to uncontaminated seawater supply) 2.0 SCIENCE PERSONNEL Karin Björkman Chief Scientist UH Matthew Church Scientist UCSC Bruce Applegate Scientist UH/HMRG Justine Afghan Scientist SIO Tara Clemente Scientist UH Lance Fujieki Scientist UH Dan Sadler Scientist UH Guido Corno Student OSU Laurie Juranek Student UW STAG: Tim McGovern UHMC/STAG Kuhio Vellalos UHMC/STAG STAG: Shipboard Technical Assistance Group 3.0 SUMMARY SCHEDULE 29 September Ship loading starting at 1200 hrs 30 September Depart from USCG station, Kodiak at 1330 hrs. Science personnel on-board by 1200. 30 Sept-Oct 9 Station 1-22 operations 9 October Pack, clean labs 10 October Arrive Honolulu. ETA 0730 hrs. Offload. 4.0 OPERATIONAL PLANS 4.1 Station 1-22 Upon arrival on Station, CTD operations will begin. The CTD casts are 0-250 m sampling at 7 depths. Winch speed should be held at 10m/min to accommodate FRRF high resolution sampling. Automated XBT deployments will be conducted off the stern, port side at predetermined positions along the transect. Occasional XCTD deployments will also be conducted off the stern. We request space on the stern port deck railing for mounting the automated XBT system. 4.2.1 Water column measurements Vertical profiles of temperature, conductivity, dissolved oxygen and fluorescence will be made with an instrument package consisting of a Seabird CTD attached to a 24-place rosette with 10 liter sampling bottles. The ships CTD winch will be used for these operations. Water samples for biogeochemical measurements will also be collected on each cast. All CTD casts will be to 250 m. 4.2.2 FRRF An optical package containing the Fast Repetition Rate fluorometer (FRRF) will be mounted on the rosette frame containing the CTD package and be deployed at each station. The CDT/FRRF package will be deployed to a depth of up to 250 m at a steady wire speed of 10 m/min during the downcast and upcast. A second FRRF will be hooked up to the uncontaminated seawater supply in one of the labs for continuous measurements. 4.2.3 Radio isotope experiments Water samples from the rosette will be used for microbial rate measurements. Radioactive tracers will be added to the water and incubate in sealed polycarbonate bottles in on-deck incubators. Radio isotopic compounds used will be 3H-leucine, and 32P-orthophosphate. All waste streams will be kept separate and all work confined in the starboard rad van. Upon completion of the cruise all radioactive materials will be offloaded. 5.0 EQUIPMENT 5.1 The HOT science party shall bring the following: 1. All required sampling bottles 2.
