Physical data holdingsOperations will consist of side-scan sonar work, CHIRP and Uniboom seismic-reflection profiling, benthic coring, sifting and sampling, ROV surveys, scuba diving surveys, weather studies, rawindsonde launches, bird surveys, deep-sea current meter retrieval/placement and plankton trawls. Operational Plans The following plans can only be considered a guide as to how the to predict weather, operations, scheduling problems and equipment failures: a) Benthic Coring/Side-Scan Sonar/CHIRP/Uniboom: Benthic cores will be taken in water depth not exceeding 300 meters with a box corer. Core samples will be analyzed and stored. At each coring site, a SeaCats cast using the McArthurs SeaCats is requested. A sub-surface profiler fish, the "CHIRP," will be towed before and during coring operations. At other times, the CHIRP will be used exclusive of the Coring operations. (A Uniboom may be aboard during parts of the cruise as a backup to the CHIRP. Side scan surveys will be conducted by USGS personnel. One of the analysis performed will be with a Gamma-ray Attenuation Porosity Evaluator (GRAPE), which uses a Cs-137 gamma-ray source. The personnel bringing this equipment aboard will provide a copy of his/her NRC permit, and the associated safety protocol and precautions. The NRC permit holder will be soley responsible for the safe operation and storage of the GRAPE device. b) Benthic Organisms: Working in conjunction with the coring project above, biologists from UCSC will be on board to opportunistically sample organisms that come to the surface in the cores. c) ROV: An ROV from NASA-Ames will be used for stereo video transects over the tops and sides of 3-6 offshore pinnacles along the Big Sur coast. These will provide baseline data on biodiversity, distributions and abundances of larger invertebrates, algae and rockfishes. The ROV has a 340m tether and is controlled from the ship. Two pinnacles will be examined on each of three days. The ROV data will also be used to select dive sites for the second leg. d) SCUBA Diving: With data from the ROV dives as a guide, the six offshore pinnacles between Pt. Pinos and Big Creek will be surveyed for biodiversity, using photography and collection/abundance measurements of organisms. Dives will be between depths of 30-100. We estimate 6 dives per pinnacle (site), for a total of 36 dives for the project. A dive plan approved by the Director of the NOAA Diving Program will be provided to the ship before any research dives are conducted. The dive plan will include the names of all potential divers. Ship divers may be asked to participate in these dives. e) Weather: Three 24-hour periods are required to sample diurnal cycles in the near coastal winds. Sampling consists of surface meteorological observations and Rawinsonde launches at intervals of 1-3 hours. Prior to ship departure, scientists will mount sensors on the ship at locations relatively free from superstructure. A drifting buoy may be launched as part of this project. During the second leg, Rowinsonde launches will also be made as time permits. f) Plankton Study: Plankton trawls will be conducted opportunistically. The plankton nets can be hand operated, but easier from a small winch. They consist of metal rings 0,5 or 1.0 meters in diameter plus a 2-meter long mesh bag. g) Deep-Sea Current Meter: This work will consist of: 1) Acoustically communicating with the current meter at 36.45N, 122.63W and sending its release command with an over-the-side transducer, 2) Picking up the current meter string upon location at the surface, 3) Deploying a replacement current meter string to be brought aboard, 4) Survey-in and communicate with the current meter, so that we are assured of successful functioning. The mooring is in about 3200 m of water. The mooring anchor will stay on the bottom and the mooring will float to the surface sans anchor. There is only about 50 m of mooring cable which can be faked on the deck. The recovery will require use of the deck capstan to pull the mooring up over the A-frame from the surface. h) Bird Surveys: Systematic observations of the distributions, abundances, behavior and correlated environmental conditions will be made opportunistically during daylight hours, using personnal binoculars as well as the ships 25x150 instrument mounted on the flying bridge. Itinerary Leg I: March 28 Arrive San Francisco (Pier 30 @ 0900 to fuel; depart pier 30 at 1500; tie up at pier 35 at 1600.), begin staging for cruise. Complete all staging by close of business on 31 March. March 30 Pre-Cruise meeting on board McArthur at 1300 hours with principal first leg researchers and ship command. April 2 Depart San Francisco at 0800 for first coring station off Ano Nuevo April 2 - April 11 1) Coring and CHIRP seismic-reflection profiling operations 24hrs/day. 2) Biologists sort cores for organisms. 3) SeaCats cast at each coring site. April 11 Evening - Put in at Coast Guard Wharf in Monterey to offload equipment; Alternative is to ferry personnel from Monterey or Santa Cruz Harbor. (Note that it may not be possible to use the aft crane to unload gear in Monterey because of the pier design. Furthermore, weather may prevent the ship from reaching the pier. Therefore, plans should be made to unload only gear which can be hand carried.) April 12 - April 14 1) Day: conduct ROV dives on Pinnacles along Big Sur Coast (from Carmel (36 o 40N) to Big Creek (aprox 36 o 50N).) 2) Night: continue CHIRP seismic-reflection profiling operations. 3) Conduct opportunistic plankton trawls. April 15 Dock in Monterey in early morning. Transfer personnel and equipment; depart Monterey by 0900. (Note that it may not be possible to use the aft crane to unload gear in Monterey because of the pier design. Furthermore, weather may prevent the ship from reaching the pier. Therefore, plans should be made to unload only gear which can be hand carried.) Notes --- Data Responsibilities a) Data and samples: disposition and archiving of data and sample scollected aboard the ship for the primary project. As the representative for the dissemination of copies of these data to participants on the cruise and to any other requesters. a single copy of all data collected by ships personnel. This data transfer will be documented on NOAA Form 61-29, Letter Transmitting Data. a list of all data collected by the scientific party. The Commanding Officer is responsible for all data collected for ancillary projects until those data have been transferred to the projects principal investigator or their designee. Data transfers will be documented on NOAA form 61-29. Copies of ancillary project data will be provided b) Records and reports: Marine Operations Abstract (MOA). McArthurs officers will maintain the MOA during the cruise. All times should be recorded as Greenwich Mean Time (GMT). The ships position will be entered for all operations, and other wise every 30 minutes or when changing course or speed. of the operations will be integrated into the MOA. of the MOA upon completion of the cruise. a cruise report within 30 days of completing the cruise.

Herring, NOAA 1801 Fairview Ave. East Seattle, WA 98102 (206) 553-4548 Notes from USGS Bulletin Brian Edwards, Rob Kayen, and others from USGS, on Monday completed a marathon box-coring program on the Monterey Bay Sanctuary shelf, collecting a total of 108 box cores. Brian and Hank Chezar continued on NOAAs ship McArthur for a several-day program to biologically explore the "Pinnicles" area, southwest of Monterey, with a new ROV of NASAs, where they hope to help NASA and ourselves learn of the utility of their new ROV, with an eye to future use. Jim Gardner, one of the architects of this sampling and ROV program, looked on from the shoreline (or from his porch in Montara), domiciled for the week with homemaker duties. MBNMS Sampling Begins: The Monterey Bay National Marine Sanctuary (MBNMS) Project recently completed 9+ days of bottom sampling on the continental shelf between the Golden Gate and Carmel and 3 days of ROV work on pinnacles off the Pt. Sur coast. During the sampling work, we occupied 108 stations as part of a cooperative effort between BUSGS, EPA, NOAA, Calif. Dept. Fish & Game (CDFG), and the UCSC biology department. We sited sampling locations in a randomly located statistical pattern developed in conjunction with EPAs EMAP design criteria. Box core samples were collected for sedimentological (BUSGS), pollution (BUSGS & CDFG), and macro- and micro-biological (USGS hence limiting our operational depth to about 45 meters. In all, the ROV has potential given appropriate project needs. Our thanks to MARFAC for squeezing this operation into their very busy April schedule. Amazing how they continually juggle, address, and meet competing needs for personnel and equipment. Mobilizing in San Francisco and demobilizing in Monterey made their work that much more difficult. Larry Kooker and Walt Olson provided their usual stellar service. Rob Kayen filled in for Jim Gardner at the last minute - Jim owes Rob big-time! My thanks also to Mike Torresan, Peter Dartnell, Fran Hostettler, Kaye Kinoshita, and Leda Beth Gray. Thanks, Brian.
