Day 18: Tripneustes and Turtles

Hey everyone! Today was a good day out here on Coconut Island. After having an extra hour in the morning to sleep, we got to go out with DAR (Department of Aquatic Resources) to put baby sea urchins (Tripneustes gratilla) out on the reefs to eat the invasive algae.

These little guys eat through a lot of invasive algae and can help clear up the reefs. We put 2,000 on reef 44 and 3,500 on reef 29. On reef 29 we also hand-picked algae and put it in burlap bags. Josie alone managed to fill 4 bags! After all the bags were on the DAR boat they left and we went to collect three more Lingula reevii samples for the tests that Sarah is performing.

Despite the fact that the day was quite good, there was a moment of sadness. As we were travelling between reefs we saw something floating on the water.

4As we got closer we were able to see (and smell) that it was a dead female turtle with a broken carapace. After briefly investigating, we notified the NOAA Turtle Research Program of the turtle and sent a few images (as shown below).

 

It made us all a bit sad, but overall the day out in the bay was fun, especially when we saw a live turtle!
