Pore water geochemistry of ODP Hole 169-1037B and Site 196-1038

Data were presented to compare pore fluids from Sites 1037 and 1038 in the Escanaba Trough, Gorda Ridge. Site 1037 constitutes the reference site, and Site 1038 is the hydrothermally affected site. The program was undertaken for two purposes: (1) to make a detailed analysis of the halide chemistry of these two sites, with the specific aim of discerning any potential differences in the generation of dissolved halides as a result of sediment diagenesis in these drill sites and (2) to investigate the geochemistry of Ba2+ and Mn2+ at these two sites to discover potential hydrothermal effects reflected in the concentration-depth distributions of these elements.

Biogeochemistry and microbiology of groundwater during acetate and bicarbonate amendment to an alluvial aquifer

These data are from a field experiment conducted in a shallow alluvial aquifer along the Colorado River in Rifle, Colorado, USA. In this experiment, bicarbonate-promoted uranium desorption and acetate amendment were combined and compared to an acetate amendment-only experiment in the same experimental plot. Data include names and location data for boreholes, geochemical data for all the boreholes between June 1, 2010 and January 1, 2011, microarray data provided as signal to noise ratio (SNR) for individual microarray probes, microarray data provided as signal to noise ratio (SNR) by Genus.
