The station was visited on July 19, 2023. During this period all components were working effectively. The anchoring systems were still in good condition with butterfly clips still securely fastened. All components were cleared of macroalgae and mooring lines remained in good condition.

In accordance with the maintenance schedule suggested by the CCCCC, the CREWS station was visited approximately two weeks post-installation on May 31, 2023 and again on June 29, 2023 to assess its condition. The state of the various components are outlined below.


Condition of CREWS Station Components

Reports had been received that the beacon was not functioning days after the station’s installation. On the first visit, efforts were made to reprogram the beacon. The required codes were entered to test the battery health and reset the beacon to its previous settings. However, it was reported once more that the beacon still remained unlit at night. On contacting the CCCCC technician, it was suggested that the beacon be completely uninstalled from the station and properly assessed prior to its reinstallation. The beacon was uninstalled on June 29, 2023. Once retrieved, the battery was changed, charged and the new flashing code programmed. It was then verified that the beacon was being activated on dim light conditions before being reinstalled on the station on July 5, 2023.

The above-water components of the station were wiped with a cloth and freshwater. One of the bolts connecting the solar panel to the station was noticeably missing. It was reattached to the frame utilising a cable tie (Figure 1). Other than this failure, all other bolts and sensors were in good condition.

Shackles on the mooring lines were in goood condition beyond a thin coating of algae (Figure 2). The butterfly clips holding the bolts on the anchors were also in good condition.

The Seabird water quality monitoring equipment was cleaned and cables remained securely fastened. Some of the butterfly clips on the cage were seen to be straitening on the first visit. This was corrected on the second visit in June. The sacrificial anode will likely need to be replaced soon.
