NURP's NIUST Targets Research of the Microbial Aspects
of Gas Hydrates
This story entered on 18th May, 2005 07:34:16 AM PST
Methane hydrates are crystalline solids of methane and
water that occur in Arctic permafrost and in deep-sea sediments
along the worlds continental margins. The gas in hydrates,
which exceeds present petroleum reserves by a factor of three and
holds sixty per cent of the worlds global carbon reserves,
may in the near future become the primary source of both gas energy
and greenhouse gas emissions. Much remains to be learned about the
geochemical and biological aspects of gas hydrates at the ecosystem
level.
The National Institute for Undersea Science and Technology
(NIUST), established in 2001 by NOAA's Undersea Research Program
(NURP), has taken a leadership role in the development of a deep-sea
gas hydrate observatory within the northern Gulf of Mexico. Throughout
the summers of 2005 and 2006, NIUST and its consortium partners,
the Department of Energys National Energy Technology Laboratory
and the Department of Interior's Minerals Management Service, will
deploy the seafloor observatory at a depth of approximately 1000
m to gather data related to the geochemical aspects of gas hydrates.
To study the chemosynthetic microbial communities associated
with hydrate systems, NIUST has recently issued a Request for Proposals
(RFP) to address fundamental methodological and/or technical questions
relevant to the development of a hydrate microbial observatory in
the Gulf of Mexico. The microbial observatory will interface with
the geochemical observatory in providing information that might
help explain the formation of hydrates. Research questions might
include, but are not limited to, issues related to microbial biodiversity,
microbial ecology, microbial physiology, and/or microbial biotechnological
applications of the hydrate microbial community. The report is available
at the NIUST web site: http://www.usm.edu/niust.
In 2006, a collaboration between NURP, NOAAs Office
of Exploration, and the Minerals Management Service will use the
deep-diving submersible Alvin to further research the chemosynthetic
communities associated with gas hydrates, as well as to understand
the linkages between gas hydrates and deep sea corals.
