Impact/Purpose:
Fluxes of nutrients from sediments can contribute to the development of hypoxia in Gulf of Mexico waters. Nitrogen fluxes are especially important because they can support phytoplankton primary production that would increase organic carbon loading to the sediments and raise biological oxygen demand. This study was undertaken to determine factors contributing to nitrogen fluxes in or out of Gulf of Mexico sediments. The results indicated potential suboxic ammonium oxidation occurring in the sediments. Suboxic ammonium oxidation is not often accounted for in nitrogen cycle models, the information obtained in this study will help improve the models.
