Gulf of Mexico Seafloor Observatory
A Cabled Ocean Observatory
in the
Gulf of Mexico

Goal
To build and operate the Gulf of
Mexico Seafloor Observatory
(GOMSO), a cabled ocean
observatory at Mississippi Canyon
Federal Lease Block 118 (MC118)

Benefits of a GOM Observatory
• Monitor the long-term effects of the
Deepwater Horizon oil release, (HR 3534)
• Expanded research in the hydrocarbon
systems, (oil, gas, hydrates) in the deep GOM
• Research and monitor rare and extreme
events
• Not affected by hurricanes or storms

Traditional Ocean Observations
• Sensor arrays towed by
a ship
• Battery-powered
sensors on seafloor
• Low sampling rates to
preserve power
• Data recovery difficult
and infrequent
• No communication with
sensors

Why is a Cabled Ocean Observatory a
Unique Opportunity?
•
•
•
•
Only way to monitor seafloor conditions in real-time
Multiple sensors for multiple needs
Provides data to academia, government and industry
Reliable power and communications

Why Locate the Observatory at
MC118?
•
•
•
•
•
Only research reserve in the GoM
Existing infrastructure in place
Unique pre-spill seafloor data and information
Less than 10 miles from Deepwater Horizon
Active research with established collaborators,
nationally and internationally
• Geologic condition similar to other deep water
drilling sites

Leveraged Investments
• Hydrate Research Consortium support by DOE,
MMS (now BOEMRE) and NOAA since 2001
• BP investment in Gulf of Mexico fiber optic
network
• Maturity of cabled ocean observatory
technologies
• State of Mississippi investment in connectivity
and supercomputing research

What will it Cost?
Estimated costs over 10 years, includes personnel,
sensors, maintenance, network service costs
– Observatory, inc. link to BP network $15 million
– Expansion of sensors and computing systems at MC118
$ 4 million
– Expansion of computing resources
$ 3 million
– Operational costs per year
$ 2.2 million
• Estimated cost for 10 years
$ 44 million

Gas Hydrates
• Ice-like solid with methane trapped in the
matrix
• Stable at low temperatures and high pressures
• Potential resource for natural gas
• Potential problem as a potent (16X CO2)
greenhouse gas
• Can cause instability on the seafloor of GOM

Why Monitor the Seafloor?
•
•
•
•
Potential energy resources from gas hydrates
Seafloor instability and energy production
Unique biological systems on hydrate deposits
Potential environmental risks from hydrate
instability
