HOT-69: Chief Scientist ReportChief Scientist: L. TUPASLoading: January 12, 1996 Departed: January 15, 1996 at 0900 Returned: January 19, 1996 at 0730 Vessel: R/V Moana Wave Chief Scientist: Dr. Louie Tupas Master: Captain Robert Hayes Deck Operations: Mr. Luigi Pozzi Electronics Technician: Mr. Will Hervig 1. SCIENCE PERSONNEL Dave Foley - UH, JGOFS Luis Tupas - UH, JGOFS Lance Fujieki - UH, JGOFS Terrence Houlihan - UH, JGOFS Albert Colman - UH JGOFS Angie Thomson - UH, JGOFS Jefrey Snyder - UH, WOCE Craig Nosse - UH, WOCE Molly Lucas - UH, WOCE Fernando Santiago-Mandujano - UH, WOCE Daniel Sadler - UH, Carbon Project John Rooney - UH, Zooplankton Project Karen Selph - UH, Zooplankton Mai Lopez - SIO, OPC/ADCP Sylvia Pinca - SIO, OPC/ADCP 2. GENERAL SUMMARY All objectives of the JGOFS and WOCE programs were accomplished. All planned stations were occupied. All core samples were taken and the 36 hour CTD burst sampling period was not interrupted. All samples for ancillary projects were taken. Floating sediment trap array and primary production array deployed and recovered succrsfully. No samples were lost during the in-situ incubation. There were no major equipment failures. The optical plankton counter was towed from Station ALOHA to Honolulu without any problem. 3. R/V MOANA WAVE, OFFICERS AND CREW, TECHNICAL SUPPORT The R/V Moana Wave continues to maintain the excellent ship support for our work. The officers and crew were most helpful and accommodating. They showed enthusiasm and concern for our work and were very flexible in receiving changes in our operational schedule. Technical support during this cruise was excellent. STAG personnel were abvailable at any time to assist in our work and made things much easier for us. 4. DAILY REPORT OF ACTIVITIES January 12, 1996; Loading Day All equipment were moved into the ship from either SNUG Harbor labs or UH on this day. All electrical and electronic connections were made for the CTD and the OPC/v-fin. All lab equipment were stowed away and secured. All instruments were tested and appeared functioning. No problems were encountered. January 15, 1996 All hands arrived on ship at 0830 and we departed at 0900. Fire and emergency drills were conducted at 1000 followed by a safety briefing by the first mate and a short science meeting. Arrived at Station Kahe at 1130. Conducted weight cast and 1000 m CTD cast. All operations and sampling accomplished by 1400. Started transit to Station ALOHA. Arrived at Station ALOHA at 2200. Sediment trap array deployment procedures began at 2300, accomplished at 2400 (0000). January 16, 1996 WOCE deep cast at 0030, completed at 0800. CTD burst sampling commenced at 0900.

Primary production array deployment commenced at 0600. CTD casts continued at 3 hour intervals. Zooplankton tows conducted at noon. Retrieval of primary production array commenced at 1800. No samples were lost. CTD casts continued at 3 hour intervals. One night tow was accomplished. Last 1000 meter cast conducted at 2100. Transit to pump tanks at 2300. January 18, 1995 Returned to the center at 0100. Deep cast conducted at 0130, completed at 0500. Proceeded to location of sediment trap array. Arrived at site and commenced recovery at 0800, accomplished at 1000. OPC deployed to conduct transects through Station ALOHA. Break-off from transect at 2100 and proceeded to Honolulu with OPC in tow. January 19, 1996 Arrived at Snug Harbor at 0800. Proceeded with unloading, accomplished at 1200. ANCILLARY INVESTIGATIONS 1.
