Quantitative PCR data from sediment samples from MPSV GREATSHIP MANISHA IODP-347 cruise in the Baltic Sea in 2013 (IODP-347 Microbial Quantification project)

Abstract

These data include the quantification of specific microbial taxa within the sediments collected during Integrated Ocean Drilling Program (IODP) Expedition 347: Baltic Sea. DNA was extracted from the interior of frozen whole round cores sampled from Little Belt, Anholt Loch, Landsort Deep, and Bornholm Basin at The University of Tennessee. For a more detailed description of drill sites, access the data set, "IODP-347 drill site locations". Primers specifically targeting the 16S rRNA gene of bacteria, archaea, anaerobic methane oxidizers (ANME-1), and Miscellaneous Crenarchaeota Group (MCG; taxonomically reassigned as the Bathyarchaeota phylum of Archaea) were used to assess abundance of these microbial groups. Abundance data was generated using quantitative-PCR (qPCR) and a non-specific, intercalating DNA stain, SYBR Green. Values were compared against a standard curve to generate copies/uL. These data were collected by Alex Shumaker as part of Dr. Karen Lloyd and Dr. Andrew Steen’s project funded by the National Science Foundation entitled, "Quantifying the contribution of the deep biosphere in the marine sediment carbon cycle using deep-sea sediment cores from the Baltic Sea".
