Cleaned 8 legs/chains-spectra-lashings, only soft growth found.

Station in very good condition - lack of accumulated biofouling.

Ongoing cleaning efforts working well.

Many plastic ties brittle, breaking , and need replacement.

Groundtruthing schedule:

0845.............Connected groundtruth CT
0900 - 1000...Transmitting period
1015 - 1045...Cleaned sensors
1000 - 1200...Transmitting period
1215.............Disconnect CT
1300.............Normal transmit begins

Notes:

Need some sort of zinc(?) protection for all 8 upper links of galv. chain touching SS shackles- accelerated deterioration noted.

Two temporary white warning floats attached to legs 2 & 6. Original yellow floats probably stolen. Bahamian smallboats cutting close to pylon at high speed, even when work crew present with dive flag.
