Site: ORPH2A
Proposed site:
ORPH2A
Priority:
Primary (subject to results from ORPH3A coring)
Position:
50°12.4'N, 45°41.22'W
Water depth (m):
3539
Target drilling depth (mbsf):
200
Approved maximum penetration (mbsf):
200
Survey coverage:
• Hudson cruise 2001/043, Huntec Lines 1–6
• Time: 6 August 2001 (JD = 218) at 22.53
• Track map–Fig. F5
• Seismic profiles–Figs. F6, F8
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:
None
Nature of rock anticipated:
Silty clay
