Beach profiling week!

This was beach profiling week. I did it with Vanessa and Holly. It was very hot, but we managed to do it fast and well. There was a very big change in the beach compared to one month ago, because of the heavy rain. We found lots of erosion on the beach, and a very big cliffs due to the loss of sand.

Measuring the segments

Otherwise, on Wednesday morning we found a depression at a nest, in Anse Cachée, near the road. It means that this turtle crawled a lot before finding a good place to lay two month ago. Only one baby turtle was still there, we presumed that the others left early morning. In total we had 153 egg shells, one intact rotten and 4 too rotten. When we dug up the nest, we expected to have lots of rotten eggs because the sand was very very wet. However, it was a successful nest because we had 153 eggs shells meaning at least they managed to crawl out and start their adventure in the sea!

Friday morning, Holly and Vanessa, found another depression in Anse Cachée. In the nest, there was still one baby turtle that was in the hole. They found 69 egg shells and 12 eggs rotten and predated. In the nest they found a crab hole. This might explain why there were only 69 hatched eggs as the crabs can sometimes drag the eggs around and predate them.
