| Description: MOBY-L326: 26 Apr 2022 MOBY Maintenance Cruise: Andrew and I went to the two buoys on 4/26 for the regularly scheduled cleaning trip. We went along to see if we could troubleshoot the Vaisala ultrasonic anemometer which has stopped working. There was nothing we could see wrong and I am not sure what the next step would be short of replacing the sensor in the field. We first went to the MN buoy and the collectors were cleaned and the antifoulant tubes replaced. The new diving procedure does not require the boat to tie up to the buoy and the divers were dropped in as the boat stood off until they needed to be recovered. Everything looked good from the surface and the collectors didn’t show any abnormal fouling. We have been having strong winds recently which could have contributed to there being no fouling of the solar panels. The divers reported everything looked fine underwater as well. We then went to buoy 272 and passed through the wind line to get there. The winds were up at the 272 site which made the diving operations more difficult. The collectors were cleaned and antifoulant tubes were replaced. The divers reported that the bottom Lu collector did appear visibly dirty before they were cleaned. The bird spikes on the Es collector were bent but did not appear to be obviously blocking it. We considered climbing the buoy to straighten the spikes but it was too rough to attempt as more damage may have been done. All the operations were completed and we returned to the site. It is curious that the set of bottom Lu collectors from 272 had significant fouling and the MOBY3 buoy did not. There is about a 6 mile difference between the buoys and from our experience 272 is behind the wind line and M3 is not, meaning the seas could be calmer at the M3 buoy. | ||
