Mangroves are some of the most fragile coastal ecosystems in the world, and export massive amounts of carbon into proximal bodies of water. This export occurs through lateral transport, where porewater is pulled through the sediment into a stream or river, after which tidal pumping of ocean water into and out of the stream deposits the carbon-rich water into the coastal ecosystems. Ground Creek in Bocas del Toro, Panama, where our experiment is located, is an ideal example of this system. A proposed hypothesis in variations on this study has been that total carbon export in the form of dissolved inorganic carbon (DIC) changes in direct correlation with tidal cycles and respiration rates. As worldwide mangrove loss continues, the question of exactly how much carbon export there is from mangrove streams has become increasingly important in the conversation surrounding ocean acidification. The acidity of mangrove sediments and the subsequent export of H+ and total alkalinity (tALK) to coral reef ecosystems is largely unknown and may influence the coral’s health in the face of anthropogenic ocean acidification. This study aims to identify the exchange of carbon, oxygen, and H+ between mangroves and coastal oceanic systems over a several diel cycles using data from an autonomous datalogging sonde which collected data on salinity, pH, dissolved oxygen, temperature, and water depth at a coral reef proximal to a mangrove system to quantify the effect of carbon export. Our working hypothesis is that the amount of acid buffering at the reef should increase as the tide moves out, correlated with a decrease in creek alkalinity and respiration, and based on the results we can attempt to calculate the overall health of both the reef and the mangrove system.
