Site: ORPH3A
Proposed site:
ORPH3A
Priority:
Primary
Position:
50°09.984'N, 45°38.273'W
Water depth (m):
3591
Target drilling depth (mbsf):
300
Approved maximum penetration (mbsf):
300
Survey coverage:
• Hudson cruise 2001/043, Huntec Lines 1–6
• Time: 6 August 2001 (JD = 218) at 23.53
• Track map–Fig. F5
• Seismic profile–Fig. F6
Objectives:
Establish late Neogene–Quaternary intercalibration of geomagnetic paleointensity, isotope stratigraphies, and regional environmental stratigraphies, and in so doing develop a millennial-scale stratigraphic template.
Such a template is required for understanding the relative phasing of atmospheric, cryospheric, and oceanic changes that are central to our understanding of the mechanisms of global climate change on orbital to millennial timescales.
Drilling program:
3X APC to refusal with drillover
Logging program:
Triple combo, FMS-sonic
Nature of rock anticipated:
Silty clay
