Description The dataset contains information of coral fertilisation success resulting from three manipulative field experiments conducted on the Great Barrier Reef (One Tree Island) and Nikko Bay (Palau). A patch of fecund adult colonies (One Tree Island: Acropora cf tenuis and Acropora digitifera; Nikko Bay: Acropora hyacinthus) were configured at each location in 3-4m depth. During spawning, eggs from a single colony were placed in 250 µm mesh containers and floated within the slick. The slicks were tracked for >60 minutes by vessel and the containers collected. Water samples for in situ sperm concentrations were also collected during the tracking period. Samples were fixed and enumerated later in the laboratory. Each collection point was georeferenced.
A similar experiment was conducted on Heron Island Reef slope but using the natural configuration of fecund corals of the species Platygyra daedalea. Eggs were collected by divers and placed in mesh containers (150 µm) in a similar manner to that described above. The slick was tracked for >80 minutes by vessel and containers collected. Each collection point was georeferenced.
