1. Del Mar mooring

7. O 2 /Chl, pH/CO 2 O 2 /Chl, pH 35m T/S, O 2 90m pH in 2011

8. Real-time data at http://mooring.ucsd.edu/projects/delmar/delmar_data.html

9. 1)have you ever been on a boat? What type? How long? How often? 2) do you get seasick? 3) have you handled ropes before? on a boat? climbing? other?

10. Activities: 1)class room session to learn about the mooring and plan the cruises, including - make cruise plans - make recovery plan (how to get the mooring on the ship safely including recovery of anchor) - make list of lab & deck equipment needed - design CTD sampling - personal preparations (clothing, transport, etc)

11. 2) recovery cruise, including - loading of ship and science equipment (1 day, 2-3 students) - instruction in safe operations, rope handling, rope&winch commands, tag line, air-tugger, winch usage, etc - CTD casts carried out by students under supervision (prep of equipment, data acquisition) (before and after recovery) - mooring operations (recovery) executed by students under supervision - cleaning of buoy and recovery of sensors from buoy - transport of buoy back to SIO

12. 3) Mechanical work - cleaning and disassembling of buoy in seaweed canyon, 2 full days but can rotate (2-4 students at one time) 4) Data analysis - read-out of raw data from mooring sensors in lab - application of calibrations - analysis of data in groups of two - design of student website for data display (to grow over the years) (to be seen)

13. 5) Prepare for deployment - help with mechanical preparation of the new mooring & - help with sensor servicing: cleaning, inspect, re-battery, possible ship to manufacturer for calibration - consider sensor sampling issues - test and set-up new sensors to be deployed - participate in full integration test 6) deployment cruise: - transport and loading of ship and equipment - pre-deployment and post-deployment CTD casts - mooring operations (deployment) executed by students under supervision

14. Class room sessions: Possible time slots Mon 4pm Wed 4pm Fri 4pm Cruise windows: Recovery 22 May (sat/sun) 24-28 June (fri-tue)

15. Notes/materials/powerpoints/software: Will be posted on anonymous ftp server geo.ucsd.edu, log in as “anonymous” with your email address as password, and go to /pub/usend/teach/spring11/ship (may need secure ftp protocol, e.g. sftp), or point your browser to ftp://geo.ucsd.edu/pub/usend/teach/spring11/ship Contact: Uwe Send, NH 446 usend@ucsd.edu 822-6710

16. Nominal mooring location 32° 55.6N, 117 ° 18.9W Need now: - Cruise plan (schedule) - Inform ship sked and STS - Packing lists (what do we need to prepare and take) - Assign instruments (to read up, get manuals, etc) - Assign people for packing, transporting, loading, setting up/securing

17. Cruise plan (Status: 2011-04-29): Distance to steam 23nm, 3hrs each way with harbor transit 3hrs steam to site 2hrs for pre-recovery CTD (or different spatial lags) plus ship met data collection 1.5hrs +1 hrs until anchor on deck 1hr for removing sensors from buoy hull (keep sensors wet, cool, and dark until calibration) 2hrs to dump data 1hr to verify data ½hr program sensors for calibration 1hr attach to CTD rosette 1hr CTD cast 3hrs steam back Decision to make: Do we want to do pre-recovery CTD, accepting long cruise duration, or do we want to do this parallel to other activities later, thinning out our personnel, or do we want to cancel the pre-recovery CTD altogether? Decision 4/29: Yes, do pre-recovery CTD. Try to obtain a towed/underway CTD system; Uwe to investigate availability (R. Pinkel?).

18. Responsibilities for instruments (2 students each): Atmospheric (wind, temperature, pressure, humidity, precipitation) and buoy controller (Gordy & Tej) Physical (ADCP, MicroCats, SeaCats) (Ruth & Roy) Biogeochemical (oxygen, chl-a fluorescence, pH) (Christina & Uriel) Duties: Read sensor/instrument manuals and bring electronic copies Make list of calibration reference required (CTD, added sensors, water samples) Confirm prior to departure that calibration references are on board and ready to operate, incl. documentation Confirm after recovery that instrument status is properly recorded on log sheets Confirm after recovery that data is downloaded Make backup copies of data Back ashore, transfer data to main data server

19. Help with loading needed: Thu., 2011-05-19: (Roy & Gordy) Pack boxes, load gear onto truck Meet in Seaweed Canyon (T-45) at 13:00 Duration 2h Fri., 2011-05-20: (Tej & Uriel) Drive gear to ship and load onto ship Meet in lab (NH 116) at 09:30 Duration 3h Mon., 2011-05-23: (Gordy & Christina & Ruth) Unload ship and drive gear to SIO, unload truck Meet in lab (NH 116) at 09:30 Duration 3h During week 2011-05-23 – 2011-05-27: Misc. gear refurbishment TBD

20. Brainstorming Packing Lists: Close-toed shoes, working (dirty) clothes, sunscreen, spare clothes, hard hats, life vests Webbing, straps, tie-down equipment, zip ties Block, bosun’s hooks, lines, heavy-duty shackles & lines for mooring pick-up Tire for buoy placement on deck Tools for every possible hardware connection (wrenches, screwdrivers, pliers, hammers) Cables with connectors matching the instruments, inductive modems Laptops, USB drives Scrubs & brushes, knives, scrapers for buoy cleaning; generic cleaning supplies Spare batteries, standard instrument-specific spare kits Cloth, tape, plastic bags to pack sensors moist & dark Water sampling equipment (bottles, chemicals, filtration gear) for salinity, oxygen, fluorescence
