Hot Off the Press: Gene Expression in the Deep Biosphere (C-DEBI contribution 137) Online in Nature
Orsi, et al. describe and analyse the first sub-seafloor metatranscriptomes from anaerobic Peru Margin sediment up to 159 metres below the sea floor, represented by over 1 billion complementary DNA (cDNA) sequence reads. Anaerobic metabolism of amino acids, carbohydrates and lipids seem to be the dominant metabolic processes, and profiles of dissimilatory sulfite reductase (dsr) transcripts are consistent with pore-water sulphate concentration profiles. Moreover, transcripts involved in cell division increase as a function of microbial cell concentration, indicating that increases in sub-seafloor microbial abundance are a function of cell division across all three domains of life. These data support calculations and models of sub-seafloor microbial metabolism and represent the first holistic picture of deep biosphere activities.
IODP: Workshop on Increasing Access to and Relevance of Marine Seismic Data
This workshop will bring together key US and international representatives of the marine geology and geophysics academic community, offshore hydrocarbon industry, and seismic data vendors. Primary objectives are to: 1) review successful examples of academic use of preexisting industry marine seismic data, 2) discuss strategies for developing joint industry-academic acquisition of new data, and 3) discuss a revised model for operations of the research vessel Langseth. The workshop will take place at the University of Texas at Austin, November 4-6, 2013. For more information, please contact Jamie Austin before September 1, 2013 or visit the workshop website.
C-DEBI Joint Science Session at SACNAS National Conference, San Antonio, TX October 3-6, 2013
SACNAS is an interdisciplinary, inclusive mentoring organization that supports undergraduates, graduate students, postdoctoral researchers and career professionals at each stage in their career. This year, C-DEBI is hosting a joint science session with 2 other STCs (C-MORE, C-MOP): From Land, to Sea, and Under the Sea: Using technology to understand water and earth systems. Questions? Contact Cynthia Joseph, C-DEBI Diversity Director at firstname.lastname@example.org
