Post-deployment (26 June 2009)


  • 180451
    • Deployed ph #5 position on FOCE.
    • Evidence that FOCE frame and pH #5 may have hit side of boat on recovery
    • passes test and calibration
  • 180358
    • Deployed pH #1 position on May FOCE   
    • passes test and calibration
  • 180511
    • out of service due to noise susceptability problem found during test and calibration
  • 180512
    • pH #1 position on May FOCE 
    • passes test and calibration
  • 180513
    • pH #3 position on May FOCE  
    • foam blocks caused the connector pins to be bent at an angle
    • passes test and calibration
  • 180514
    • pH #4 position on May FOCE 
    • foam blocks caused the connector pins to be bent at an angle, though less than 513
