The Angel Reef CREWS given a basic maintenance service on 21st April 2014. No obvious physical damage was noted. Fouling was minimal and consisted of 3 barnacle spat. The wiper "garage" was replaced, and the coper coating on the CT probe. The failure of the Turbidity probe to pass the QC test remains unresolved (the same issue exist for BUTO1), even though it all seems right during the cal. Recommended action is a firmware upgrade.
Possible error with barometric readings. Pressure ranges from 1013-1015 millibar throughout the day. A 1millibar change suggest a 10m displacement.
