- 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.
This site is for recording maintenance records of the Institute of Marine Affairs (Trinidad and Tobago) & NOAA CREWS station for data management purposes. Please update this blog whenever new operations are performed in the field, so that NOAA/AOML can coordinate data management efforts with the CREWS field efforts.

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.
