SITE SUMMARIES (CONTINUED)

Site: IRD1A

Proposed site:	IRD1A
Priority:	Primary
Position:	49°52.667'N, 24°14.287'W
Water depth (m):	3884
Target drilling depth (mbsf):	300
Approved maximum penetration (mbsf):	400
Survey coverage:	• Redrill DSDP Site 609 • CH-94 (20 July 1983) • Vema 23 (20 October 1966)
Objective:	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:	To be determined
Nature of rock anticipated:	Foraminifer-nannofossil ooze
