This experiment was designed to describe the degradation in seawater of red mangrove leaves in the Bay of Panamá and compare results with findings from similar experiments reported in the literature and performed at other latitudes.

The red mangrove (Rhizophora mangle L.) decomposition experiment showed a 50% dry weight loss after 27 days of immersion in the Say of Panama. The concentration of nitrogen in the mangrove leaves at the beginning of the experiment was 0.3%, hut after 93 days of immersion it increased to 2.9 %. Similarly, the initial concentration of phosphorus was near 0.04% and by the end of the experiment it rose to 0.13%.
