Carbon and Nitrogen Stable Isotopic Patterns in South Florida Coastal Ecosystems: Modern and Paleoceanographic Perspectives

Four Thousand Years of Habitat Change in Florida Bay, as Indicated by Benthic Foraminifera

“…Hurricanes disrupt the interannual variability and mean annual salinity of Florida Bay, increasing the flow of freshwater along the northern boundary (Kelble and others, 2007). Our hypothesized freshening from hurricanes is supported by stable isotopes of carbon from another Trout Creek core of this project (Evans, 2009) that indicate a large negative excursion at 1929 (65 yr) that indicates a large flux of mangrove material washed into the bay. The 1926-1935 hurricanes occurred at the end of an Atlantic Multidecadal Oscillation cool phase associated with frequent hurricanes and high rainfall (Enfield and others, 2001).…”
