Our work in Los Jardines de la Reina (Gardens of the Queen) in Southern Cuba was a cruise of opportunity in collaboration with Amy Apprill at Woods Hole Oceanographic Institution. This paper has been published, and additional work on nitrogen cycling in corals is waiting for a motivated individual to come along!
There is plenty more to reveal about corals and the biofilms / microbial structure of their mucus. Particularly of interest to us is how the physical structure shapes nutrient and chemical gradients (e.g., oxygen and pH) and how these in turn shape microbial ecosystem dynamics and biogeochemistry.
