SN #2296 8/1/02 (213.1) - 9/23/02 (266.9)

• Last calibrated
• 11/4/02
• after pump failure/C cell replatinized

SN #2295 10/27/02(300) - 3/25/03 (84.6)

• Last calibrated:
• 4/29/03
• recalib/replatinized - node maintenance

SN #2296 4/14/03 (104.75) - 4/15/04 (105.11)

• Last calibrated:
• 11/4/02
• Notes:
• 4/20/03 (110.7) - 5/1/03 (121.6) - poor data/cycled power/cleared pump

SN # 3544 (no pressure sensor) 8/04 - 12/16/04

• Last calibrated:
• New sensor
• Notes:
• SBECTD pump use discontinued 8/04

SBECTD #2295 12/30/04 - 6/8/05

• Last calibrated:
• 6/04

SBECTD #3544 8/27/05 - 11/12/05

• Last calibrated:
• 3/15/05
• Notes:
• deployed working SBECTD 3544 8/27/05 but failed in field moved ports a number of times in attempt to revive it but never succeeded
• recovered 11/12/05 - noise in line heavily fouled with barnacles

• Last calibrated:
• 8/05 - internal pump installed
• Notes:
• heavy anti-foulant applied
• quick drop in salinitity .. tried power cycling ... fouled?
• cleaned up insitu - 3/7/06 - sm

• Last calibrated: 05/13/2005
• with pressure & internal pump
• Notes:
• heavy anti-foulant applied
• funnel @ intake with copper screen over mouth
• data became garbage on 098
• replaced cable on 4/19/06

• Last calibrated:
• WHOI Cal lab 5/20/06 - internal pump installed
• Instrument mounted sideways (new **) = height is 76"
• Notes:
• heavy anti-foulant applied
• Stopped 2006149 17:20+ March 29 - PUMPON makes it fail
  Had to reenter 8/29/05 calibration coefficients by hand

Running - but user be ware (is it clogged?)

• Last calibrated: checked at WHOI cal lab 7/06
• no pressure & internal pump

• Last calibrated: 5 October 2005
• checked at WHOI cal lab (MS) 7/06
• mounted vertically again ... intake at 66" (1.67 m + 0.14m?)
• funnel @ intake with copper screen over mouth
• .... perhaps trouble was diver air trapped in pump?
• CHANGED Sampling scheme NCYCLES/INTERVAL was 4/2 now 50/60

SBECTD 2295 deployed 10/10/06 - 4/23/07

• Last calibrated: 26 August 2006
• internal pump physically removed and disabled in software
• mounted vertically again ... intake at 66" (1.67 m + 0.14m?)
• no funnel @ intake with copper screen over mouth
• CHANGED Sampling scheme NCYCLES/INTERVAL was 4/2 now 50/60
• simultaneously deployed with CTD2 and TRAN1
• CTD2 was deployed at same height as SBECTD

SBECTD 4476 deployed 10/11/2010 - 5/2/2011 (stopped working 3/7/2011) - corroded pins

• Last calibrated: ?
• Pump Installed (impellor replaced by jf 9/10)

New CTD installed 9/27 for OASIS project
NOTE: processing wasn't on until 1/4/2012 -- so OcnDat salinity is from CTD2 or missing so get from SBECTD files

Updated: 2/9/12-jjf
