Learn about our deep biosphere research directly from seagoing expeditions on the JOIDES Resolution and other expeditions associated with C-DEBI research.
Explore the hidden wonders of the deep continental slope of the northern Gulf of Mexico from offshore Mississippi to Texas: its bubbling mud volcanoes, quiet brine lakes, seafloor gas hydrates, oil seep sites, and also the seafloor near the Macondo wellhead at over 1500 meters depth, will be visited by deepsea submersible Alvin, its pilots and science observers. Follow the cruise blog March 29 – April 23, 2014 to explore and document the deep Gulf of Mexico ecosystem, its lasting damage and beginning recovery almost four years after the Deepwater Horizon blowout.
We returned to North Pond in 2011, a site located in the very middle of the Atlantic Ocean, to investigate the microbiology of this location which has been studied nearly continuously for its geological, geophysical, and hydrological characteristics since first drilled in 1975/1976. See the blog from the first expedition in 2009 and Return to North Pond Expedition 336 blog linked to Scientific American. Link to the Adopt-A-Microbe Project and the Classroom Connection initiative from the Expedition 336 Hub.
Scientists and educators on the Hydrogeology at Juan de Fuca Expedition (Summer 2011) explored how water flows in the earth’s crust beneath the seafloor, and examined geochemistry, rock alteration and microbes living in the seafloor – all off the west coast of the United States. This expedition is a direct follow-on from IODP Expedition 327 (2010), when subseafloor observatories (CORKs) were placed in the seafloor on the Juan de Fuca ridge. The returning expedition to these installations used the Remotely Operated Vehicle (ROV) JASON to download data, retrieve samples, and make any necessary repairs to on-going experiments. See the Expedition Hubs (2011 and 2010) and the Adopt-A-Microbe activities (2011 and 2010).
The South Pacific Gyre Microbiology Expedition (2010) penetrated a total of 630 m at seven different drill sites to define the physical and chemical limits of subseafloor microbial life in tectonic and oceanographic settings not yet explored! See the Expedition Hub and Adopt-A-Microbe version 2.0.
