Water Depth
1070m
Sediment Thickness
450m
Target Depth
480m
Approved Maximum Penetration

Seismic Coverage
Deep Penetration
seismic reflection
Primary Line(s): UB 0103 airgun
Location of Site on line SP 246
Crossing Lines(s): AWI 91091

High resolution seismic reflection
Primary Line(s): AWI Parasound
Objectives
1. Drill and sample the most complete stratigraphic pelagic sediment section to meet the paleoceanographic objectives for understanding the paleo Arctic Ocean circulation, its relationship with global climate, and changes in sediment flux to the basin.
2. Penetrate and sample acoustic basement to meet the tectonic objectives.
Drilling Program
Drill and sample 2 APC/XCB holes to 450 mbsf and 1 APC/XCB/RCB hole to 480 mbsf.
Triple APC to refusal, XCB 30 m into basement and log.
Downhole Logging Program
Ice conditions permitting, the aim is to log at least one hole. At a minimum, formation density, porosity, resistivity, velocity, and gamma-ray spectrum will be logged.
Nature of Rock Anticipated
Sediments: Silty clays, clays, siltstone, claystone
Basement: Continental crust rock: lithology is not known, but could range from volcanics to carboniferous rocks.
