SITE SUMMARIES (continued)

Sites: Alt AMFW-05A and 06A
Priority:
Alternate 2
Position:
Along seismic Line Meg-4, endpoints of potential transect at 30.15°N, 42.12°W to 30.24°N, 42.11°W
(See Fig. F8)
Water depth (m):
1600–2200
Sediment thickness (m):
1–2
Target drilling depth (mbsf):
Single bit penetration
Approved maximum penetration (mbsf):

Survey coverage:
Specific sites to be determined by time available and subsea camera survey between common midpoints 3900 and 5400
Objectives:
Transect of ridge-parallel sites along the central dome to investigate heterogeneity in microstructure, geochemistry, and petrology along the dome moving from the ridge segment end toward its center
Drilling program:
Single bit to destruction or until objectives reached
Logging program:
Contingent upon depth of penetration and hole conditions
Nature of rock anticipated:
Serpentinized peridotite, gabbro
