For each independent treatment, aliquots of 7.5 mL flange slurry (approx. 29 g
wet weight and 20 g dry weight) were transferred into Balch tubes in an
anaerobic chamber, and supplemented with 15 mL of sterile artificial seawater
media designed to mimic the geochemical conditions within a hydrothermal
flange (400 mM NaCl, 25 mM KCl, 30 mM CaCl2, 2.3 mM NaHCO3, 14 mM NaSO42-, 1
mM H2S, and 50 uM dissolved organic carbon - consisting of equimolar
proportions 10 uM of pyruvate, citrate, formate, acetate, lactate) under a
pure nitrogen headspace.\\u00a0
 
Concentrations of sulfide, sulfate and dissolved organic carbon (DOC) were
varied independently to investigate concentration dependent effects on the
rates of SR. The range of experimental conditions tested was determined from
previously published concentration profiles of aqueous species modeled as
functions of temperature and position within the Grotto vent structure (Tivey,
2004). Concentrations were varied by orders of magnitude within the modeled
ranges to simulate conditions representative of different mixing regimes
between seawater and vent fluid (Table 1). The range of DOC (which we
approximate as a mix of pyruvate, citrate, formate, acetate, lactate \\u2013
most of which have been identified to varying degrees within vent fluid and
are known carbon sources for heterotrophic SR in culture) concentrations
tested were based on the average DOC concentrations measured within diffuse
fluids at the Main Endeavor Field (Lang\\u00a0et al., 2006; Lang\\u00a0et
al.,\\u00a02010). Hydrogen sulfide was present as H2S (pKa\\u00a0in seawater of
6.60) across all the conditions tested (Amend & Shock, 2001). Incubations were
carried out at pH 4 (to simulate the pH of end-member Grotto vent fluid and
the average calculated pH of\\u00a0mixed fluids in highly reduced zones within
the flange; Tivey 2004) as well as pH 6 (representative of the calculated pH
in fluid mixing zones; Tivey 2004). All the results are presented and
discussed in the context of the initial measured media conditions.";

"Description from NSF award abstract:
Current estimates suggest that the volume of ocean crust capable of sustaining life is comparable in magnitude to that of the oceans. To date, there is little understanding of the composition or functional capacity of microbial communities in the sub-seafloor, or their influence on the chemistry of the oceans and subsequent consequences for global biogeochemical cycles. This project focuses on understanding the relationship between microbial communities and fluid chemistry in young crustal fluids that are responsible for the transport of energy, nutrients, and organisms in the crust. Specifically, the PIs will couple microbial activity measurements, including autotrophic carbon, nitrogen and sulfur metabolisms as well as mineral oxide reduction, with quantitative assessments of functional gene expression and geochemical transformations in basement fluids. Through a comprehensive suite of in situ and shipboard analyses, this research will yield cross-disciplinary advances in our understanding of the microbial ecology and geochemistry of the sub-seafloor biosphere. The focus of the effort is at North Pond, an isolated sediment pond located on ridge flank oceanic crust 7-8 million years old on the western side of the Mid-Atlantic Ridge. North Pond is currently the target for drilling on IODP expedition 336, during which it will be instrumented with three sub-seafloor basement observatories.
The project will leverage this opportunity for targeted and distinct sampling at North Pond on two German-US research cruises to accomplish three main objectives:
1. to determine if different basement fluid horizons across North Pond host distinct microbial communities and chemical milieus and the degree to which they change over a two-year post-drilling period.
2. to quantify the extent of autotrophic metabolism via microbially-mediated transformations in carbon, nitrogen, and sulfur species in basement fluids at North Pond.
3. to determine the extent of suspended particulate mineral oxides in basement fluids at North Pond and to characterize their role as oxidants for fluid-hosted microbial communities.
Specific outcomes include quantitative assessments of microbial activity and gene expression as well as geochemical transformations. The program builds on the integrative research goals for North Pond and will provide important data for guiding the development of that and future deep biosphere research programs. Results will increase understanding of microbial life and chemistry in young oceanic crust as well as provide new insights into controls on the distribution and activity of marine microbial communities throughout the worlds oceans.
There are no data about microbial communities in ubiquitous cold, oceanic crust, the emphasis of the proposed work. This is an interdisciplinary project at the interface of microbial ecology, chemistry, and deep-sea oceanography with direct links to international and national research and educational organizations.";

"This project characterizes rates of microbially mediated sulfate reduction from three distinct hydrothermal vents in the Middle Valley vent field along the Juan de Fuca Ridge, as well as assessments of bacterial and archaeal diversity, estimates of total biomass and the abundance of functional genes related to sulfate reduction, and in situ geochemistry. Maximum rates of sulfate reduction occurred at 90°C in all three deposits. Pyrosequencing and functional gene abundance data reveal differences in both biomass and community composition among sites, including differences in the abundance of known sulfate reducing bacteria. The abundance of sequences for Thermodesulfovibro-like organisms and higher sulfate reduction rates at elevated temperatures, suggests that Thermodesulfovibro-like organisms may play a role in sulfate reduction in warmer environments. The rates of sulfate reduction observed suggest that - within anaerobic niches of hydrothermal deposits - heterotrophic sulfate reduction may be quite common and might contribute substantially to secondary productivity, underscoring the potential role of this process in both sulfur and carbon cycling at vents.
This project was funded, in part, by a C-DEBI Graduate Student Fellowship.";

Using tabledap to Request Data and Graphs from Tabular Datasets

tabledap lets you request a data subset, a graph, or a map from a tabular dataset (for example, buoy data), via a specially formed URL. tabledap uses the OPeNDAP (external link) Data Access Protocol (DAP) (external link) and its selection constraints (external link).

The URL specifies what you want: the dataset, a description of the graph or the subset of the data, and the file type for the response.

Tabledap request URLs must be in the form
https://coastwatch.pfeg.noaa.gov/erddap/tabledap/datasetID.fileType{?query}
For example,
https://coastwatch.pfeg.noaa.gov/erddap/tabledap/pmelTaoDySst.htmlTable?longitude,latitude,time,station,wmo_platform_code,T_25&time>=2015-05-23T12:00:00Z&time<=2015-05-31T12:00:00Z
Thus, the query is often a comma-separated list of desired variable names, followed by a collection of constraints (e.g., variable<value), each preceded by '&' (which is interpreted as "AND").

For details, see the tabledap Documentation.
