A complete cleaning (CTD validation, cleaned all sensors, chains, lines, and spar) at the CREWS Station in La Parguera, Puerto Rico, was done Tuesday, October 5th, 2010 by Wessley Merten. The groundtruth validation sensor was placed at 11:53 and was removed at 15:15pm. All surface and subsurface sensors were visibly intact. All rigging, lines, baseplates, sensors, and the spar were cleaned, but need more attention later this month. There were reports that the groundtruthing sensor was not transmitting or receiving data during the last complete clean. Therefore, prior to plugging the sensor I examined the interface and didn't see a source for a loose/bad connection. In addition, I inspected the cable that the sensor connects to and besides the significant biofouling that was removed I did not discover any damage.
The next cleaning will be performed within two weeks.
