While diving this week to do some further chain inspections and to retrieve a lost cell phone (only for the SIM card), I encountered large green masses of floating algae on the bottom of the basin. And when it breaks off and floats to the surface, we see these large islands. About a month ago, on a previous dive, I took another photo (#4198) of one of the legs of the new dinghy ramp. Notice how little there is of the green stuff there was then. And now, the second photo (#4201) shows how much larger these growths have become! That white object is a 1½ turnbuckle tube to provide some scale. And if one of these are touched, the just seem to explode and float away in bits and pieces. They did leave quite a green film on my gloves!
And we are starting to see the large grass-type vegetation starting to show up. When we were looking for a lost mooring, U1, the grass in the outer basin is much more advanced. I had to terminate the dive when my equipment, and me, became entangled in the grass. It is very thick and totally covers the entire floor of the basin.
