The vagaries of field research

We were planning four transects today. But there is always a gap between what we plan on paper and what we experience in the field, and I had to arbitrate. However, all the scientists, 80 in total, are currently on deck day and night to multiply the collections, sorting and classification of specimens.

1st dive on Saya de Malha.

With my partner, we dived to 42 meters, with 40 minutes of actual diving on the bottom and 40 minutes of decompression. The bottom was very white and made up of sand with small coral debris. The ground was soft which allowed us to lift and collect elements quite easily. All this was covered with a very rich fauna and flora.
