Live corals are primarily Agaricia tenuifolia. DISCUSSION Our surveys demonstrate that Pond A in Cat Cay and Pond C in Manatee Cay are low- flow environments with some diurnal temperature fluctuations and with naturally elevated DIN concentrations in comparison with nearby reefs. Elevated DIN concentrations were measured primarily along coral ridges at the pond openings and at the bottom of the ponds. Recent investigations (Diaz and Ward, 1997; Miller-Way, personal communication) have demonstrated that common sponges and their associated cyanobacteria found on prop roots and in the benthos are capable of extremely high rates of NO, production. Other potential sources of DIN are.
