Heading1
 The main objective and delivery from
the workshop is a catalogue on ideas
and possibilities regarding international
research and technology. Each
participant is invited to suggest
research topics within his or her own
scientific field.
WORKSHOP ON CABLE-BASED OCEAN OBSERVATORIES,11-12 JUNE 2007, RADISSON SAS HOTEL NORGE, BERGEN
Main topics
 Climate
– Methane gas hydrat
– CO2 leakage and deposition
 Geosphere-hydrosphere-biosphere interactions
– Continental margins
– Volcanic spreading ridge
– Natural energy sources
 Geo hazard
– Earthquakes
– Slope instabilities
WORKSHOP ON CABLE-BASED OCEAN OBSERVATORIES,11-12 JUNE 2007, RADISSON SAS HOTEL NORGE, BERGEN
Climate - Methane gas hydrat
 Motivation/research topics
– Different regime compared to Canadian areas
 High latitude reaction to global warming
– Change of methane flux (>50 years)
– Geo hazards (continously monitoring of stress)
 Plate tectonic
– Petroleum province (>10 year)
 Area of interest
– Plate margins
– Arctic ocean
WORKSHOP ON CABLE-BASED OCEAN OBSERVATORIES,11-12 JUNE 2007, RADISSON SAS HOTEL NORGE, BERGEN
Climate - CO2 leakage and deposition
 Motivation/research topics
– Deposition
 Basalt is more reactive than sandstone (convert
CO2 gas to carbonate)
 Area of interest: Basalt with impermeable
sediment blanket on top
– Leakage
 Controlled detection of leakage by injection of
CO2 into sedimentary basins (small scale)
 Array of seismic sensors on the sea floor in
sandstone environment
 Area of interest: Sediment
