Site: LAB3A
Proposed site:
LAB3A
Priority:
Primary
Position:
58°02.169'N, 48°27.57'W
Water depth (m):
3350
Target drilling depth (mbsf):
300
Approved maximum penetration (mbsf):
400
Survey coverage:
• Line BGR-2 (shotpoint 4000)
• Track map–Fig. F9
• Seismic profile–Fig. F10
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 drill over
Logging program:
To be determined
Nature of rock anticipated:
Silty clay
