3 4.0. OPERATIONAL PLAN 4.1. SWAC Station sampling: SWAC 3 (Intake site; , ; depth 545 m), SWAC 2 (Down slope; , ; depth 175 m) and SWAC 1 (Diffuser site; N, W; depth 105 m) will be occupied on the first day of the cruise for approximately 6 hours total. 4.2 OTEC Station sampling: (21º 17.8' N; 158º 11.8' W) 4.3. Station ALOHA (22 45'N, 158 W with 6 nm radius) McLane and PIT Sediment trap array deployment Upon arrival to Station ALOHA, 2 floating sediment traps arrays will be deployed at a location within Station ALOHA, to be determined en route to ALOHA by local current conditions. The sediment trap arrays will be deployed from the stern, using the A-frame and large Sea-Mac winch. Power requirement for the winch is 440 VAC, three phase at 10 amps. After deployment we request that the bridge verify that the radio transmitters are functioning and directionally correct. The PIT sediment trap array will be equipped with 2 ARGOS satellite transmitters (platform # s 3028, 60482), 2 strobe lights, and radio transmitters (RF Ch69, MHz) and will consist of 12 crosses and 144 PIT traps. The second array will consist of two conical shaped McLane sediment traps with motorized collection cups (AKA Sediment Trap Upside Down- STUD Array). The STUD array will be equipped with 2 ARGOS satellite transmitters (platform # s 60484, 84857), 2 strobe lights, and radio transmitters (RF Ch74, MHz). Both arrays will drift for about 9 days before recovery. Daily positions of the array shall be transmitted by directly to the ship (argosfix@km.soest.hawaii.edu, password: argosfix), therefore the ship will not need to keep within sight of the array until the time of the recovery. Assistance from the bridge is requested in plotting the drift track of the array. We request the use of the ship's radio direction finder for locating the array before recovery. NOTE: depending on the speed and distance this array travels, the date for recovery may shift to maximize time for operations at Station ALOHA On the first day at Station ALOHA (9/17), CTD casts will recommence Water column measurements Vertical profiles of temperature, conductivity and dissolved oxygen will be made with the OTG instrument package consisting of a Sea-Bird CTD attached to a 24- place rosette with 12 liter Bullister sampling bottles. We will need the ship s CTD winch and A-frame for these operations. Water samples for biogeochemical measurements will be collected on each cast. There will be an additional 3

4 instrument to be included with the OTG CTD package an ISUS, which is a real time, chemical free sensor for measuring nitrate. Its power requirement is amps at 12V Diaphragm pump water collection Large volume water collection from the surface and DCM will be conducted in the evenings using a diaphragm pump. This operation is expected to take approximately 4-5 hours per night totaling 24 hrs. Approximately 16 hrs of pumping will be done at the DCM and 5 hrs of pumping at the surface for a total of ~ 1000L of water. This operation requires the use of the ships compressed air Gas Array deployment A free drifting incubation array will be deployed once during this cruise, for a six day duration, starting on the third day of the cruise at Station ALOHA. We request the use of the A-frame for this operation and will also use the Sea-Mac winch. The array is equipped with two ARGOS satellite transmitters (platform # s 1833, 60481) and radio transmitters (RF Ch72, , MHz) ing positions to argosfix@km.soest.hawaii.edu, password: argosfix), a strobe light and a radio transmitter ( MHz) VANE sampling Trace-metal clean samples will be collected using VANE samplers attached to the Kevlar covered wire (MVP wire, 0.33 ). Five VANE casts will be conducted in total. Three VANE casts will be conducted at a target depth of 800m, with 3-6 VANES attached to the wire. Two VANE casts will be conducted with target depths of m and m respectively. Each cast will have 6 VANES attached to the wire. The deep cast (Depths: 250, 500, 700, 1000, 1200, and 1400m) and a shallow cast (Depths: 25, bottom of mixed layer ~50, 75, 100, chlmax~130, and 175m) will be conducted on consecutive days. In conjunction to the VANES deployments, CTD water collection targeting the same depths as the VANES will be conducted. The VANES will also be deployed through the A-frame on the back deck Surface hand net tow Surface net tows are hand-deployed off the stern for 45 minutes daily between 11:00-12:00. We request that the ship remain stationary during these tows Automated Trace Element Sampler (ATE) Each day that the ship is occupying Station ALOHA, the ATE will be hand deployed off the back deck to a depth of 10 m to collect at Trace Metal Free Sample. The ATE will be recovered after 30 minutes in the water. The ATE is approximately 1 tall and 4 in diameter, weighting 5 lbs. If the ship has been stationary at ALOHA for previous cruise activities, it is requested that the ship steams approximately minutes up current from 4

5 current position prior to each ATE deployment to limit contamination of the trace metal sample from the ship s hull Hyperpro The Hyperpro is a profiling unit with one up-looking and one down-looking hyperspectral radiometer, a WET Labs ECO-BB2F triplet (measuring Chlorophyll-a fluorescence and backscattering in the blue and red wavelengths), temperature and conductivity sensors. This instrument also incorporates a ship mounted surface radiometer. The Hyperpro will be deployed daily during the cruise. The Hyperpro is deployed from the stern through a small block hung from the A- frame. The instrument is hand-lowered and retrieved. Each deployment will consist of three profiles before the instrument is retrieved and take approximately 45 min to complete. 4.4 Seaglider One seaglider (sg512) will be deployed as one of the first operations upon arriving at Station ALOHA and another seaglider (sg148) will be recovered prior to departure from Stn ALOHA. Throughout the cruise, both seagliders will be diving and profiling in the Station ALOHA area and at times transiting within the circle boundaries of Station ALOHA. The seaglider GPS fixes and alert info will be sent to the onboard "seaglider@km.soest.hawaii.edu" which is accessible both by the science party and Captain. ARGOS info is also as follows: sg512 ARGOS sg148 ARGOS (to be deployed) (to be recovered) It is requested that when the KM is within the circle, the OTG initiated cronjob (forwarding the ship's position) send out the message to poulos@soest.hawaii.edu. Typical frequency of this position once/30mins during deployments/recovery and once/3hrs for normal ops Deployment of sg512 will be done off the stern and once in the water and the tether is slipped from the glider the ship is free to move off somewhat & conduct other ops. This typically takes about an hour to setup on deck and get the okay to put in the water via the A-Frame. When the seaglider has finished a few initial dives, the land based pilot will send the status to the ship's science party and the vessel is free to transit as need be. Suggested recovery of sg148 is recommended to be done as prior, off of the stern. 4.5 Sediment Trap recovery On the late evening/ early morning of September 26/27th, the ship shall transit for the recovery of both sediment trap arrays. The A-frame and the Sea-Mac 5

6 winch will be needed to retrieve the sediment trap arrays. After the arrays are recovered, the ship shall transit to Honolulu Harbor. NOTE: depending on the speed and distance this array travels, the date for recovery may shift to maximize time for operations at Station ALOHA. 4.6 Acoustic Doppler Current Profiler The ship s acoustic Doppler current profiler (ADCP) will be in operation during the duration of the cruise. The OTG electronics technicians will be in charge of the ADCP system. 4.7 Thermosalinograph, pco 2 system, Fluorometer, and meteorological system The ship s thermosalinograph, pco 2 system and fluorometer sampling the uncontaminated seawater supply system will be in operation during the duration of the cruise while the ship is outside of Snug Harbor. The ship s meteorological system shall be in operation throughout the cruise. Access to real-time underway data through the ship s network will be required. The OTG technicians will be in charge of the thermosalinograph, pco 2 system, Fluorometer, and meteorological suite operations. Whenever pumping of the ship s tanks is needed, it must be conducted outside the circle that defines station ALOHA (Sect. 1.0). To avoid disruptions in the schedule, this operation should be coordinated with the chief scientist and co-chief scientist. 5.0 EQUIPMENT 5.1 The science party shall be bringing the following: 1.
