Biological and Isotopic Changes in Coastal Waters Induced by Hurricane Gordon
The effects of a major storm event (Hurricane Gordon) on the biogeochemistry of Atlantic coastal and Gulf Stream waters were investigated during a research cruise in November 1994. Prestorm, NH+ 4, NO- 3, and PO-3 4concentrations were consistently well below 1 μM, whereas after the storm, nutrient c...

4concentrations were consistently well below 1 μM, whereas after the storm, nutrient concentrations were higher in the surface-water samples:$>$2 μM, in some instances. Primary and secondary (bacterial) production were stimulated by factors of 5 and 2, respectively, up to 4 d following the storm. Bioassay experiments showed that additions of inorganic N stimulated chlorophyll a (Chl a) concentrations,14CO2fixation, and stable isotope fractionations both before and after the storm, but the addition of phosphate had a greater impact in post-storm experiments. The δ15N of particulate nitrogen (PN) varied from +5 to +1.5permil before Gordon, then afterward attained a consistent value of +3.0permil. Sedimentary organic δ15N values were similar to water-column organic N, and the δ15N of dissolved NH+
4from surface sediments (+4.0permil) almost matched the δ15N of water-column particulates. These results indicate that storm-generated winds mixed sediments along with dissolved nutrients into surface waters, which supported a rapid increase in water-column primary production. |
