The meeting occurred from 0830 to 1400 with the Marine Technician Groups, and the scientists continued the meeting to discuss berthing, specific sampling plans and other issues until 1545. 1) Ship schedules May-June Cruises (dates/times are best guesses based on vagaries of loading/offloading times and times of high tides) a) Thompson (SeaSoar/Higher Troph Obs) a1) 27 May 0900 - Depart Seattle a2) 28 May late or 29 May early - Arrives Newport (time dependent on tide) a3) 29 May - Begin loading in Newport a4) 31 May late or 1 June early - Depart Newport (time dependent on tide) a5) 17 June - Arrive Newport (time dependent on tide) a6) 18 June late or 19 June early - Depart Newport (time dependent on tide) a7) 20 June - Arrive Seattle b) Wecoma (station sampling/process cruise) b1) 29 May - load and depart Newport (Note: ship is available for hand-loading on 28 May) b2) 18 May - arrive Newport and offload c) Charter Vessel (TBD; salmon trawling) c1) ca. 1 June - Depart Newport c2) ca. 18 June - Arrive Newport and offload July-August Cruises (dates/times are best guesses based on vagaries of loading/offloading times and times of high tides) d) Revelle (SeaSoar/Higher Troph Obs) d1) 29 July - Begin loading in Newport (worst case is loading cannot begin until 30 July late) d2) 31 July late or 1 Aug - Depart Newport (time dependent on tide) d3) 19 Aug 0800 - Arrive Newport and offload (time dependent on tide) e) New Horizon e1) 26 July - Depart San Diego for transit to Newport e2) 29 July or 30 July - Arrive Newport (time dependent on weather and tide), load, and depart (31 July would be latest departure expected) e3) 19 Aug 1200 - Arrive Newport (tide dependent) and offload e4) 20 Aug - Depart Newport for transit to San Diego e5) 24 Aug - Arrive San Diego f) Charter Vessel (TBD; salmon trawling) f1) ca. 1 Aug - Depart Newport f2) ca. 18 Aug - Arrive Newport and offload 2) Loading Logistics a) Shoreside, long-reach crane is required to load and offload BigEyes and stanchions a1) Thompson Load (crane available in Seattle) a2) Thompson Offload (crane must be rented in Newport) a3) Revelle Load (crane will be available at commercial dock in Newport to offload Goldfinger Coring Van; BigEyes and Stanchions need to be transported from OSU storage yard to commercial dock, where they can be loaded with that crane) a4) Revelle Offload (crane must be rented in Newport) b) 20' Temperature controlled van from SIO will be shipped by truck to Newport, where it will be used as a refrigeration van on the Wecoma cruise (01 Deck), stored in Newport between cruises (OK'd by Fred Jones), and used as an isotope van on the Revelle. Gross weight of van is <10000 lbs, so can be lifted into place using Wecoma crane. Van will be return transported to SIO on deck of New Horizon. c) Isotope van on Thompson will be loaded in Seattle. 3) Specific Ship Activities/Equipment a) Thompson (May-June 2002) a1) SeaSoar; deployed through A-Frame; requires a block; all other gear provided by SeaSoar group; requires electical power for winch; Willis will provide shackle? a2) HTI Acoustics Package; stays in water continuously while towing and doing station work; only recovered if vessel needs to move at >8 kts.; fixed length cable (74m) from fish to deck box/computer; 3m depth at 8 kts; 15m depth at 0 kts; requires a towpoint that provides ca. 15' clearance from side of vessel and clearance from a) ships-drive, and b) other deployed instruments (SeaSoar, SLOWDROP, CTD, TSRB); dead weight of HTI is ca. 500 lbs; options for tow-point discussed included the "high-up crane", a fixed davit, and some outrigger jig.

Tech Meeting Topics NOTE: Woody, please forward to Tammy (I don't have her email). Thanks. Reminder: 11 March 2002 Ch.Sci./Mar.Tech Meeting Ocean Admin. Bldg Seminar Room Ocean Admin. Bldg Oregon State University Corvallis, OR 97331-5503 Time: 0830-1430 (to 1600 if needed for PI discussions) In response to my earlier message with discussion topics for next Monday's meeting, there were a couple of topics suggested as additions to the agenda. They are inserted below in CAPS. One topic is from Marc Willis (his msg is): Hal, One additional issue which will need discussion is deployment and towing of HTI bioacoustics package. Daryl has talked with Bob Wilson at SIO about this, and I think that the UW folks are aware of it but not sure. For both cruises, this is likely the item which will cause the most heartburn. Marc The other topic raised by Bill Peterson regards finding/renting a refrigerated van for incubating experiments for use on the Wecoma cruise in May-June. The New Horizon has a coldroom already (capable of holding approx. 8-10C) and Bill would like a similar facility for the May-June cruise on the Wecoma. Bill's backup plan is to use many different temperature controlled refrigerators, but the temperature control is less stable than a dedicated van, and it will require additional space in the Wecoma's dry and/or wet lab interior space. I spoke with Woody S. several months ago about this, and he indicated that the SIO van he thought would be available for May-June would NOT be. He also indicated that SIO had two other cold-room vans, and he would look into their availability and if one was available the costs to ship it to Newport for the May-June cruise. Woody, could you revisit this issue prior to next Monday's meeting. Thanks. If available and we use it for the Wecoma cruise, would it be possible to keep the van until late August and return it to SIO on board the New Horizon when it returns south after the August cruise? Marc and Fred, is there a secure place in the yard at Newport where the van could be stored from late J une till late August, if needed. ------------------------------------- For those of you attending from out of town and requiring overnight accomodations, there is a web site run by the Corvallis Business and Convention Bureau (www.visitcorvallis.com) with information on lodging, dining and shuttle service from the Portland Airport. Portland is about 2 hours from Corvallis by shuttle/car. Here is an unprioritized list of topics that need some discussion during the meeting. 1) EXACT ship schedules for each of the three vessels during May/June (Wecoma, Thompson, charter) and setting of preliminary (at least; EXACT if possible) schedules for the July/August cruises (New Horizon, Revelle, charter). 1a) May/June - Wecoma loads/unloads in Newport - Thompson departs Seattle; arr. and loads in Newport; offloads in Newport; transits to Seattle - Charter loads in Newport? 1b) July/August - New Horizon transits SD to Newport; loads Newport and departs when?; returns and offloads in Newport; transits to SD - Revelle loads and offloads in Newport; science begins when? - Charter loads in Newport? 2) Loading Plans - see item (1) for details - shoreside crane needed to lift bigeyes into place on 03 deck (up-forward)? - AVAILABILITY OF A COLD-ROOM VAN AVAILABLE FOR THE WECOMA MAY-JUNE CRUISE 3) Sampling plan for "mesoscale" SeaSoaring--cruise tracks 4) Sampling plan for "finescale" SeaSoaring--cruise tracks - be flexible in exact sites OR - preselect Heceta Bank and Cape Blanco as two sites (repeat 2000 work) - Letelier/Abbott drifter releases/recovery during "finescales" 5) Sampling priorities in the event of lost weather days early in the cruises 6) Nutrient sampling - will it require someone from Hales nutrient group on board "station" vessel (e.g., is a bunk available?) 7) MOCNESS sampling 8) Small vessel work from "station" vessel 9) COMMUNICATIONS - between vessels and shore (satellite imagery) - AVHRR - Strub - SeaView software from Ocean Imaging - Ocean Color (SeaWiFS, MODIS) - who is primary contact? - between vessels - Wecoma-Thompson Wireless system (<10 km range) - email (frequency; binary attachments) - ftp server site (size; cell phone) - FAX - centralized web site for transfer of graphics - sideband radio 10) space needs on each vessel - bunks by task (names if possible) - winch placement; incubator placement; wires - dry lab layouts - wet lab layouts 11) Ships equipment needed - flow through systems recorded with navigation - met observations - ADCP continously; who will set these up on each ship (Pearce?) - CTD - MOCNESS 12) Event Logging 13) New International Safety/Compliance Standards (appl. to Thompson and Revelle only this year); need for documented SOPs (Standard Operating Procedures) 14) PUBLIC OUTREACH Activities (primarily for July-August cruise) 12a) high school teacher on Revelle providing daily reports to HMSC 12b) reporter on Revelle (maybe) 12c) "OPEN SHIPS" prior to sailing (involving Revelle, New Horizon, and Wecoma?) 15) DEPLOYMENT AND TOWING OF THE HTI ACOUSTICS SYSTEM FROM THE THOMPSON AND REVELLE If you have additional topics that need to be discussed, please let me know.
