3 Partnerships Natural Resources Canada Earth Science Sector Geological Survey of Canada Universities ArcticNet Canadian Arctic Shelf Exchange Study (CASES) University of Quebec, Rimouski University of New Brunswick Dalhousie University Inuvialuit Joint Secretariat (IJC) Oil Industry Devon Energy Corp. Government Indian and Northern Affairs Canada (INAC) Department of Fisheries and Oceans (DFO) Canadian Hydrographic Service (CHS) Institute of Ocean Sciences (IOS) Program of Energy Research and Development (PERD) Canadian Coast Guard

4 ArcticNet ArcticNet Sub-project 1.6 Goals collect as much bathymetry data as possible, study the geology and geohazards of the Passage and investigate the paleoceanography and sea ice regime for the past 10,000 years

5 Outline 1.6 Geoscience Research Introduction / Methods Preliminary Results Future Work for 1.6

6 Technology

7 Multibeam Echosounder GPS Satellite Multibeam Profiling Singlebeam Profiling

8 Sub-bottom Profiler 10 km

9 Box Coring

10 Piston Coring

11 Core Analysis

12 Data Coverage 2003 Amundsen (CASES) 2004 Amundsen (ArcticNet) 2005 Amundsen (ArcticNet) Core Samples (ArcticNet & CASES)

13 NW Passage Geology HOLOCENE SEDIMENT!! Bedrock 10 km Glacial Sediment

14 Lancaster Sound Core 009

15 Lancaster Sound Core Site Selection

16 meters Olive grey, massive silty clay Tan calcareousrich mud Olive grey, massive silty clay With increasing amounts of bioturbation, mottling and pyritization Lancaster Sound Core 009 (collected in 2004) ,700 10,500 yr BP Medium-light brown silty clay interlaminated with very fine silt,

17 Glacial Features Amundsen Gulf

18 Glacial Features Glacial Fluting / Streamlined Drumlins in Amundsen Gulf, ~400m water depth

19 Flutes / Drumlins -Up to 40m high above surrounding seabed -300m wide -4km long -Indicates ice flow direction to the NW

20 Flutes in the NW Passage

21 Ice Scours Amundsen Gulf

22 Ice Scours 410m water depth 3.6m deep scour ~400m water depth Widespread scouring in the area Deepest scour occurs in 410m water depth Scours as deep as 3.6m into the seabed

23 Low 175 stand m Late-Pleistocene Sea Level (~120m below present) bathymetry contour Area of Active Scouring Scoured area during (Present Regime, ~55m low stand (assuming water depth) present scour regime) Low stand Late- Pleistocene Sea Level

24 Amundsen Gulf 410m Deep Ice Scours What caused these features? Glacial Ice Dynamics (iceberg calving, etc.)? More extreme ice scour regime than present?

25 Amundsen Gulf Glaciation Indicators Features formed at glacier front Features formed under glacier

26 Barrow Strait Pockmarks / Gas Vents

27 Pockmarks/Gas Vents ~300m water depth 9 gas vents observed Active venting Most of the features are oriented along a NW-SE line One of the vents appears to be active

28 Future NW Passage Research -Continue analysis of piston and box cores collected in the NW Passage -Continue to collect multibeam and sub-bottom data in the NW Passage -Build on some of the multibeam survey blocks from CASES and ArcticNet -Collect piston cores over some of the seabed features (i.e. drumlins, slump, ice scours, etc.) -GSC will expand our research in the NW Passage over the next 3 years -International Polar Year (IPY)
