1. Del Mar mooring

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

10. Hypoxia observations 35m near-bottom

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

12. 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? Interests and expertises: Emily: pH, Durafet calibrations, coupling (covariance) of pH, oxygen, T timeseries (absent Apr 12- May 22, Jun 8-10) Susan: pH, oxygen, chl (absent May 12-22) Sam: ADCP, chlorophyll Matthew: communication circuits, timeseries analysis, Raymond: met sensors, circuits, C

13. 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)

14. 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

15. 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

16. 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

17. Class room sessions: Possible time slots Mon Tue Wed Thu Fri Cruise windows: Recovery 25 May (Friday) Deployment 15-22 June (to be confirmed)

18. 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/spring12/ship (may need secure ftp protocol, e.g. sftp), or point your browser to ftp://geo.ucsd.edu/pub/usend/teach/spring12/ship Contact: Uwe Send, NH 446 usend@ucsd.edu 822-6710

19. Nominal mooring location 32° 55.6N, 117 ° 18.9W Need before the cruise: - 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

20. Cruise plan (Status: 2012-05-10): Distance to steam 23nm, 3hrs each way with harbor transit Do 2 CTD casts next to mooring for instruction and testing (2 groups) Calibrations: No pH since sensor died (battery) Oxygen: remove sensors from mooring, dump data, reprogram for calibration CTD cast, attach to rosette, and do calibration cast with water samples Chlorophyll: similar to oxygen, filter samples and freeze the filter paper but data are only useful at night – do this off Pt. Loma around 8pm Leave 8am, arrive 11am, 2 CTD casts 11-12:30, mooring recovery 12:30-14:00. Clean buoy and remove sensors and dump microcat data until 17:00, deep cast with microcats (Seacat ?), 18:00, steam to Pt.Loma 20:00, O2/chl calibration cast until 21:00. Arrive 22:00.

21. Responsibilities for instruments: Atmospheric (wind, temperature, pressure, humidity, precipitation) and buoy controller: new data from wind sensor (Matthew and Raymond) Camera (Matthew and Raymond) Physical (ADCP, MicroCats, SeaCats): ADCP Sam Biogeochemical (oxygen, chl-a fluorescence, pH) : pH - Emily, O2 - Susan, chl - Susan/Sam 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

22. Help with loading needed: 2012-05-23: Karen, Sam Pack boxes, load gear onto truck Meet in Seaweed Canyon (T-45) at 11:00 Duration 2h 2012-05-24: Matthew and Raymond Drive gear to ship and load onto ship Meet in lab (NH 116) at 10:00 Duration 3h 2012-05-??: Unload ship and drive gear to SIO, unload truck Meet in lab (NH 116) at 09:30 Duration 3h During week 2012-05-?? – 2012-05-??: Misc. gear refurbishment TBD

23. 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
