Hageberg WORKSHOP ON CABLE-BASED OCEAN OBSERVATORIES 11-12 JUNE 2007, RADISSON SAS HOTEL NORGE, BERGEN

2. WORKSHOP ON CABLE-BASED OCEAN OBSERVATORIES,11-12 JUNE 2007, RADISSON SAS HOTEL NORGE, BERGEN 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.

3. 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

4. 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

5. 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
