Geochemical data from sediments and porewaters of shallow sediment cores from hydrothermal seeps in the Guaymas Basin, Gulf of California

The dataset includes organic carbon and nitrogen isotope data, as well as elemental abundance data from marine sediments that were obtained by push corers from hydrothermal seeps in the modern Guaymas Basin, Gulf of Mexico. Also included are pore water measurements of ammonium concentrations and nitrogen isotopes of dissolved ammonium, as well as sediment temperatures.

Statement: The isotopic data were obtained by flash combustion of dry solid samples in an elemental analyzer (EA Isolink) connected via a Conflo IV to a gas-source isotope-ratio mass spectrometer (MAT253) at St Andrews. Elemental abundances of metals were obtained from Australian Laboratory Services, where samples were analysed by ICP-MS and ICP-OES following bulk digestion. Ammonium concentrations in pore waters were measured by UV-VIS spectrophotometry at St Andrews. For isotope measurements of ammonium, a microdiffusion method was used to trap the dissolved ammonium on fibre glass filters, which were then analysed by the same EA-IRMS setup as solid sediment samples. For details, see Rochelle-Bates et al. (in review) "Quantifying hydrothermal ammonium recycling and implications for the marine biosphere: A case study from the Guaymas Basin, Gulf of California"
