HAWAII OCEAN TIME-SERIES KM0304 General Cruise Plan VESSEL: R/V Kilo Moana, University of Hawaii MASTER OF THE VESSEL: Captain Gray Drewry CHIEF SCIENTIST: Karin Björkman, University of Hawaii STAG Deck Technician: ? STAG Electronics Technician: Steve Poulos Load: April 4 (?), 2003, 0900 HST Departure: April 7, 2003; ? HST (from fuel dock 1600 HST) Arrival: April 17, 2003; 0800 AST (Kodiak, AK) 1.0. SCIENTIFIC OBJECTIVES The objective of this cruise is the collection of hydrographic and biogeochemical data along the transect from Oahu, HI to Kodiak Island, AK. We plan to occupy approximately 21 stations enroute to Kodiak with higher resolution sampling across the transitional zone between the northern North Pacific gyre boundery and sub-Arctic waters approximately located between 30N-35N. 1.1 SCIENTIFIC OPERATIONS Station Activities Station 1 (ALOHA) CTD operations (0-200m), FRRF optics cage Station 2-21 CTD operations (0-200m), FRRF optics cage Underway/continuous ADCP, thermosalinograph, fluorometry Mapping XBT, XCTD FRRF (hooked up to uncontaminated seawater supply) 2.0.

SUMMARY SCHEDULE 4 April Ship loading starting at 0900 hrs 7 April Depart from Snug harbor at 0800 hrs? Science personnel on-board by 0730? Fuel dock. Depart 1600 hrs. 8 April Station 1 (ALOHA) operations 8-16 April Station 2-21 operations 16 April Pack, clean labs 17 April Arrive Kodiak, AK. ETA 0800 hrs, offload. 4.0. OPERATIONAL PLANS 4.1. Station ALOHA (22 45'N, 158W with 6 nmile radius) Upon arrival at Station ALOHA CTD operations will begin. The CTD casts are 0-200 m sampling at 6 depths. This cast is to be followed by FRRF optics cage cast deployed through the A-frame off the stern. 4.2. Station 2-21 Station operations are the same as for Station 1. 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. 4.2.2. Water column measurements Vertical profiles of temperature, conductivity and dissolved oxygen 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 this operation. Water samples for biogeochemical measurements will also be collected on each cast. All CTD casts will be to 200 m. 4.2.5. AC-9/FRRf An optical package containing the AC-9 and the Fast Repetition Rate fluorometer (FRRf) will be deployed at all stations. The package will be deployed to a depth of up to 200 m at a steady wire speed of 10-20 m/min during the downcast and upcast. We will use an electric hydraulic winch (HOT) and request the use of the ships power for this winch. 5.0 EQUIPMENT 5.1 The HOT science party shall bring the following: 1. All required sampling bottles 2. All required chemicals and radio isotopes 3. Containers for radioactive waste (two each liquid and solid) 4. Large vacuum waste container 5. Liquid nitrogen dewars 6.
