some observations about buoy status

The following is a brief status update based on a close examination of the data record, in a similar manner to an earlier update last May.
  • The analog RH/AirT sensor remains nonfunctional. Based on my direct observation of similar problems with the Calabash Caye buoy I believe this is probably a buoy wiring problem and not a failure of the instrument itself.
  • The EXO's CT2 sensor does appear to be more reliable than the problematic CT sensor it replaced. Also there is a clear signal in the salinity data when local calibrations were redone in March and again in May, as described by Jonathan Gomez.
  • DO data disappear following the March visit, the explanation for which can be found in another Jonathan Gomez update.
  • Diagnostic data continue to suggest that the interior of the 'Main' canister is unacceptably moist, which has been true (but worsening) since last December's maintenance operation.
