Prouty Vulnerability of Coral Reefs to Bioerosion from Land-based Sources of Pollution

Ocean acidification (OA), the gradual decline in ocean pH and [CO32- ] caused by rising levels of atmospheric CO2, poses a significant threat to coral reef ecosystems, depressing rates of calcium carbonate (CaCO3) production, and enhancing rates of bioerosion and dissolution. As ocean pH and [CO32- ] decline globally, there is increasing emphasis on managing local stressors that can exacerbate the vulnerability of coral reefs to the effects of OA. We show that sustained, nutrient rich, lower pH submarine groundwater discharging onto nearshore coral reefs off west Maui lowers the pH of seawater and exposes corals to nitrate concentrations 50 times higher than ambient. Rates of coral calcification are substantially decreased, and rates of bioerosion are orders of magnitude higher than those observed in coral cores collected in the Pacific under
equivalent low pH conditions but living in oligotrophic waters. Heavier coral 15N values pinpoint not only site-specific eutrophication, but also a sewage nitrogen source enriched in 15N. Our results show that eutrophication of reef seawater by land-based sources of pollution can

Trump puede redoblar su ofensiva en el 2018. Nosotros también.

Con más abogados industriales y lobbies dirigiendo agencias federales habrá más ataques contra las protecciones ambientales. Pero no estaremos solo a la defensiva, iremos a cualquier lugar donde se pueda avanzar, sin descartar ningún estado y de manera internacional.
