deployment

The deployment procedures used for the TSRB is designed to follow the ocean optics protocols for SeaWiFS calibration and validation (J.L. Mueller and R.W. Austin, SeaWiFS Technical Report Series, V25, Feb 1995).  The deployment procedure is outlined below:

  • casts are made as close in time as possible to the SeaWiFS overpass (between 12:00 and 14:00 HST).
  • ancillary data are also available from PRR casts made simultaneous to the TSRB measurements.
  • to start the deployment, the sensors are first checked for fouling and cleaned if necessary.
  • the instrument is then lowered into the surface of the water from the stern of the ship.
  • the instrument is then allowed to float away from the ship (to the rear), tethered by the data cable, to a distance of about 10 m. 
  • the instrument is left to make measurements for about 10 minutes.
  • the instrument is then retrieved, rinsed with fresh water and allowed to dry.
