The 3-d quadrat on Humingbird Cay in the Bahamas was successfully revisitied adding new observations and data downlaoded form last year. It was removed from the water late last summer before a hurricane but survived and was reinstalled this March.
The most direct observations was the
Montastrea (common star coral) and
Porites (finger coral) have not changed much as might be expected with their relatively slow growth rates. But there was an "invasion" of algae not observed last year. The cause is unknown and probably not of any concern. The fun part of observing the same loaction over time is that you start to see things that you either might not been aware of before or over time more things simply happen in that space (time to observe them happening). My favorite observation was that this year there was a pair of juvenile French Angel fish inhabiting the area, and the rays seemed to be more abundant.
Water temperature, air temperature, pH, and density were also measured and very similar to last year's readings. If I get a chance to observe again next year it will be interesting if any short-term trends can be identified.
In the images you can see two rays swimming right by the 3-d quadrat, the yellow algae being gently moved away to take a picture of the star coral, the porites with some white disease growing on it, an Angel fish near the 3-d quadrat, and some tomato-shaped anemones I did not observe last year - but are probably not new.
This project is made possible by Dr George Elmore at Tufts Unvierstiy and Mr Van Bernhard. Thanks also to Forrest for his invaluable assistance.
