The brown filamentous algae is now growing very quickly and it will be necessary to clean the underwater camera every week from now until early July. Cleaning on a two week cycle corresponding with spring low tides makes cleaning fairly easy through the winter. However, the intermediate clean corresponds with a neap high tide and up to 2 metres more water over the camera. This makes cleaning more challenging!

The underwater camera was cleaned to day in the middle of a hail shower, which made life interesting. Underwater visibility was only moderate and the water temperature was 10.0C. A large number of two-spot gobies are now in residence in the camera pontoon and one grey mullet was also seen. The algae and sponges are all very colourful at this time of year with lots of greens, reds, and browns.

On the walk back the scurvy grass bloom is coming to an end while the thrift is just beginning its main spring bloom.
