This week's feature is the winning image in the Research category.
Description: During a research expedition to a remote island in the east of Papua New Guinea, I took this photo of the CARIOCA project (Coral reef acclimatization to ocean acidification) team. At the end of one of our research dives, I was floating on the sea surface trying to capture the atmosphere of doing underwater research in the beautiful islands and coral reefs of Papua New Guinea. In this photo, the team is performing experiments in the sea while on the surface a small boat is waiting to pick them up back to the research vessel. The crystal clear and calm sea of this area created the perfect scenery for half-under half-above sea photo.
