“…Standards between 120 and 900 µM were freshly prepared using 5% artificial seawater. We found significant differences in standard curves between those prepared in the artificial seawater as described in Gieskes et al (1991) and those prepared in pure water. Because of what appears to be a strong dependence of the kinetics of the reaction on time, drift could be substantial.…”

“…Analytical protocols are summarized below. In many cases, these protocols are based on those of Gieskes et al (1991), Murray et al (2000), and the IODP user manuals for new shipboard instrumentation, with modifications as indicated. However, as described in the following subsections, in many cases the instrumentation and protocols used during Expedition 329 supersede those cited above.…”

“…A primary standard was prepared by adding a weighed amount (~0.5642 g) of sodium silicofluoride (Na 2 SiF 6 ) to 18.2 M water. This standard was used to produce a curve of calibration standards according to the instructions given in Gieskes et al (1991). Standards between 120 and 900 µM were freshly prepared using 5% artificial seawater.…”

“…Mineralogy of the sediment was measured using a Phillips APD 3600 powder X-ray diffractometer. Sediment texture, chemistry, and mineralogy are reported in Table 1. In the laboratory, the concentration of C1 in the pore fluid was measured by titration with silver nitrate with a precision of---l% [Gieskes et al, 1992]. Concentrations of SO4, Mg, and Ca were measured at the University of Florida by ion chromatography.…”

The structure of microbial populations near chemosynthetic faunal communities of two geographically and geologically distinct deep-sea hydrothermal vent fields were quantitatively evaluated using catalyzed reporter deposition-fluorescence in situ hybridization (CARD-FISH). The hydrothermal vent of the Southern Mariana Trough (SMT) was dominated by colonization of gastropods in the low-temperature diffuse hydrothermal fluid, whereas macrofauna in mixing zones of the Mid-Okinawa Trough (MOT) consisted of polychaetes, galatheid crabs, and bivalves. A quantitative comparison revealed that the microbial community of the SMT hydrothermal vent field is significantly different from that of the MOT and is strongly influenced by mixing conditions between reduced hydrothermal fluid and oxygenated seawater. In particular, a high proportion of Epsilonproteobacteria was found in the SMT hydrothermal fluid, which is composed of approximately 88 % seawater. In contrast, sulfur oxidizers in Gammaproteobacteria were most abundant near vent fauna habitats in the MOT. Our results suggest that the SMT hydrothermal environment is distinct from that of the MOT and affects the community structure of macrofauna and microbial flora.
