3 Hydrocarbon Resources Barents Sea Greenland Probability for one field with more than 50 MMBOE Russian FederaMon Canada USA Source: US Geological Survey

4 Most resources are within 200 M 4

5 What is UNCLOS? UNCLOS: United Nations Convention on the Law of the Sea main part negotiated from , came into force in 1994 defines rights and responsibilities for how nations may use the world s oceans Replaces 1958 Geneva Conventions on the Law of Sea Ratified by 161 states, inc. all Arctic nations except for the US Ratified by the Kingdom of Denmark on November 16,2004 5

6 What is Article 76 of UNCLOS? Defines the Continental Shelf of a coastal state Article 76 provides the mechanisms by which a coastal state may claim rights to the seabed and subsoil of submarine areas. Includes natural resources of the seabed and subsoil defined as mineral and non-living resources living organisms belonging to sedentary species 6

7 Article 76 of UNCLOS A key aspect is that it defines how a coastal state may claim rights beyond the 200 nautical mile (M) EEZ. Claims must be submitted, with documentation, within 10 years after a state ratifies the convention Kingdom of Denmark deadline: November 16,

8 8

9 Foot of Slope (FOS): maximum change of gradient at the base of the continental slope 1 nautical mile = mile = 1852 meters Formula lines Either FOS + 60 nautical miles or 1% sediment formula Constraint lines Either 350 nautical miles or 2500 meter isobath nautical miles 9

10 Note that the key to an extended shelf claim is first and foremost Morphological Geology can be used to support a claim, but is not part of the legal definition. 10

11 Key Documentation Required The 2500 meter isobath - must be mapped convincingly The Foot of Slope both require multibeam and single beam mapping Sediment thickness and continuity seismic reflection and refraction data 11

12 Bathymetric Data 12 Background: IBCAO, M. Jacobsson, Stockholm University

13 Kingdom of Denmark - Areas of interest 2 areas: the Faroe Islands 3 areas: Greenland Submission for the area N of the Faroe Islands: April 2009 Submission for the area S of the Faroe Islands: late 2010 Ongoing work in the areas around Greenland with a deadline in

14 Greenland Extended Shelf: Southwest coastal area: Data collecmon to document a claim completed, analyses in progress NE Greenland: Some data collecmon completed - final data required planned in 2011 North of Greenland: Significant progress, but much more required. Planned in 2011, 2012?? 14

15 Focus on the Arctic Ocean north of Greenland 15

16 North of Greenland UNCLOS Documentation Field work from 2006 to 2009 Focus on the acquisition of bathymetric and seismic data. The white ellipses show the LOMROG III work areas planned for 2012 or White stippled lines unofficial median lines. 16

19 Seismic Reflection Data Seabed Sediments Example of processed seismic reflection data from LOMROG II: Provides a measure of sediment thickness - but this is in traveltime (seconds), not in meters Basement 19

23 Cooperation with other countries All activities of the Continental Shelf Project in the Arctic Ocean on behalf of the Kingdom of Denmark have been in cooperation with other countries: LORITA (2006), LOMBAG and LOMGRAV (2009) expeditions based on Canadian logistics LOMROG I (2007) cruise with Oden: 50/50 cooperation with the Swedish Polar Research Secretariat, Stockholm University and Canada LOMROG II (2009) cruise with Oden: cooperation with the Swedish Polar Research Secretariat and Canada with Russian participation Initiative to continue and strengthen Nordic Cooperation in Polar Science 23

24 International cooperation Logistical cooperation during data acquisition between all Arctic coastal states with the following benefits: Sharing of logistical resources Considerable cost savings Scientific cooperation: Better understanding of the geology of the Arctic Ocean => better supported submissions Consultations and discussions regarding scientific issues of specific features, i.e., the Lomonosov Ridge between Canada, Denmark and the Russian Federation with USA as an observer have taken place since

25 Continental Shelf Project Scientific Outcome Data policy: results published in international scientific journals data will be released (bathymetric data already released for regional compilations (IBCAO) Increased knowledge of an area with sparse data tectonic evolution, disputed plate boundaries paleoclimate history, Arctic is very sensitive to global climate change physical oceanography, water mass exchange between the Arctic and other oceans sensitive ecological systems 25

26 Continental Shelf Project Associated Research LORITA (2006): Søren Rysgaard (sampling of ice cores) LOMROG I (2007) cruise with Oden: Søren Rysgaard in cooperation with Roskilde Univeristy (sampling of ice cores), DTU-Space (ice thickness); Swedish projects (geology, oceanography, accumulation of mercury) LOMROG II (2009) cruise with Oden: Oceanography (DMI and Göteborg University), Søren Rysgaard in cooperation with University of Washington (sampling of ice cores), DTU-Space (ice thickness), DTU-CBS (Nicolai Blom DNA of the Polar Seas), DTU-Aqua (Lone Gram - bacteria); Swedish projects: geology, plankton ecology (Danish participant) 26

27 Ice Core Sampling LORITA (2006) Project organized by Søren Rysgaard 27

36 Future activities In 2011 a 24 day cruise with Oden is planned in the area off NE Greenland acquisition of bathymetric, refraction, and reflection seismic data, geological sampling. Decision pending availability of Oden. Possibilities for Danish science projects will be announced through the Danish Centre for Marine Research. In 2012 a third LOMROG cruise is planned in the area north of Greenland. 36
