ITINERARY 27 July Start of cruise. Embarked Paul Murakawa (fish), Jason Leonard (fish), Jill Zamzow (fish), Dave Gulko (coral), Bernardo Vargas Angel (coral dis­ ease), Holly Bolick (invertebrates), Aline Tribollet (algae), John Mitchell (algae), Brian Zgliczynski (towed-diver survey/fish), Ben Richards (towed-diver survey/fish), Rusty Brainard (towed-diver surveylhabitat), Jake Asher (towed-diver surveylhabitat), Kyle Hogrefe (oceanography), Ron Hoeke (oceanography), Sean Guerin (oceanography), Kevin Lino (oceanography), Russell Moffitt (data manager), and Jim Bostick (dive­ master/chamber operator). Departed Honolulu at 0830, en route for Makapuu Point and Manana (Rabbit) Island off windward Oahu. An in­ troductory meeting was held for all scientific personnel and new crew­ members at 0900. A dive safety meeting was held for all divers at 0930. Following arrival off Makapuu Point, commenced coral reef ecosystems surveys consisting of one Rapid Ecological Assessment (REA) dive off Kaohikaipu Island (OAH-13), three towed-diver habitatlfishlmacro­ invertebrate surveys, five shallow water conductivity-temperature-depth I PIFSC Cruise CR-08-013 ~"T~ Issued 31 October 2008 /~~ ~~~'" ; @ Printed on Recycled Paper <4., .;r 09r4fENT Of c,c'Il' (CTD) casts, and one oceanography team reconnaissance dive. Medical Officer Chris Walsh was embarked via small boat from the Makai Pier at 1430. Following small boat operations, the ship departed for Kauai at 1800. At 1900, the scientific party conducted a planning meeting to dis- cuss operations for the next day. 28 July Arrived at Kauai Island at 0730 to commence field operations. The REA team (less two members) partially occupied two established sites on the northeast and north sides of the island (KAU-1, KAU-2) and established one new site off northwest Kauai (KAU-13). The team worked short- handed due to inability to launch the ship’s Zodiac Inflatable boat, HI-5, because of moderate sea conditions. The towed-diver survey team com- pleted five dives east to west from near Papaa Bay to Hanalei Bay. Found a Fish Aggregating Device (FAD) grounded on the reef at position N22 14.5208 W159 25.1988. The oceanography team deployed an ocean data platform (ODP) anchor in Hanalei Bay and conducted 13 shallow water CTD casts and performed 5 water quality profiles during which water samples were taken to be later analyzed for chlorophyll and nutrient con- tents. At 1800, departed for west Molokai Island. 29 July Arrived off west end of Molokai Island at 1200 to commence reef assess- ment surveys. The REA team conducted one REA survey at site MOL-5 and aborted a second REA survey due to strong current conditions. The towed-diver survey team conducted three dives along the west end from Ilio Point south to and around Laau Point. The oceanography team recov- ered and replaced two STRs, conducted six 30-m CTD casts. During the night the ship conducted three 500-m CTD/water quality casts during which 15 water samples were taken to be later analyzed for chlorophyll (15 samples) and nutrient (15 samples) content. 30 July Arrived off northwest coast of Maui Island at 0730 to commence reef as- sessment surveys. The REA team conducted three new REA surveys off Mokeehia Islet (MAI-10), Kahakuloa Point (MAI-11), and Kanounou Point (MAI-12). The towed-diver survey team conducted six dives along the windward facing northwest coast from Nehe Point to northwest to Ka- nounou Point. The oceanography team deployed one subsurface tempera- ture recorder (STR), conducted nineteen 30-m CTD casts, and performed eight water quality profiles during which water samples were taken to be later analyzed for chlorophyll and nutrient contents. During the night the ship conducted two 500-m CTD/water quality casts during which 10 water samples were taken to be later analyzed for chlorophyll and nutrient con- tent. 31 July Arrived off northeast coast (Alenuihaha Channel) of Maui Island at 0730 to commence reef assessment surveys. The REA team conducted three new REA surveys off Alan Islet (MAI-13), Mamalu Bay (MAI-14), and Kaapahu Bay (MAI-15). The towed-diver survey team conducted six dives 2 along the southeast coast from Alan Islet southwest to Mamalu Bay. The oceanography team conducted twenty-seven 30-m CTD casts, and per- formed nine water quality profiles during which water samples were taken to be later analyzed for chlorophyll and nutrient contents. During the night the ship conducted two 500-m CTD/water quality casts during which 10 water samples were taken to be later analyzed for chlorophyll and nutrient content. Ship-based multibeam mapping operations were also conducted. 01 August Continued reef assessment surveys off southeast Maui in the Alenuihaha Channel. The REA team conducted one repeat REA site at Nuu Landing (MAI-3) and two new REA surveys off Nakaohu Point (MAI-16) and in Kanaloa Bay (MAI-17). The towed-diver survey team conducted six dives along the southeast coast from Mamalu Bay southwest to Kamanamana Point. Another Fish Aggregation Device (FAD) buoy number NL was found grounded on the reef as position N20 35.6751 W156 16.2306. The oceanography team deployed an EAR and an STR in La Perouse Bay, conducted twenty-one 30-m CTD casts, and performed three water quality profiles during which water samples were taken to be later analyzed for chlorophyll and nutrient contents. Command of ship assumed by CDR Carl Groeneveld as CDR Kuester, CDR Swallow, and Medical Officer Walsh disembarked via small boat to Maalaea Harbor. Embarked Medical Officer William Foust.

Ship-based multibeam mapping opera- tions were also conducted. 04 August Conducted reef assessment surveys off northeast coast of Lanai Island north from Shipwreck Beach to near Manele Bay. The REA team con- ducted one new REA survey off Shipwreck Beach (LAN-8) and two es- tablished sites (LAN-4 and LAN-5). The towed-diver survey team con- ducted six dives along this same coast from Shipwreck Beach to Kamaiki Point. The oceanography team recovered and replaced one STR, con- ducted twenty-three 30-m CTD casts, and performed seven water quality profiles during which water samples were taken to be later analyzed for chlorophyll and nutrient contents. During the night the ship conducted two 500-m CTD/water quality casts during which 10 water samples were taken to be later analyzed for chlorophyll and nutrient content. Ship-based mul- tibeam mapping operations were also conducted. 05 August Conducted reef assessment surveys off south coast of Lanai from Kaa on the east coast to Nahahoa on the west coast. The REA team conducted one new REA survey off Kaa (LAN-7) and two established sites (LAN-3 and LAN-6). The towed-diver survey team conducted five dives from Manele Bay to north of Nanahoa on the west coast. The oceanography team re- covered and replaced one STR, conducted fourteen 30-m CTD casts, and performed one water quality profile during which water samples were taken to be later analyzed for chlorophyll and nutrient contents. During the night the ship conducted conducted one 500-m CTD/water quality cast during which five water samples were taken to be later analyzed for chlo- rophyll and nutrient content. 06 August Conducted reef assessment surveys off north coast of Maui from Pauwela Point to Kahului after initial launch plans further east were aborted due to adverse wind and sea conditions.
