1998 cruise).
• Deep penetration seismic reflection R/V Maurice Ewing
Ew9009 1003.
• Seismic grid CH0698 (collected Cape Hatteras CH0698,
1998 cruise).
• Swath bathymetry available but not on databank
(collected
during CCGS Fredrick G Creed April 1996
and R/V Onrust
September 1998 cruises).
Imagery:
• No photography or video available.
Sampling:
• Grain size analysis from Onrust September 1998 cruise.
• Rock sampling or dredging: not applicable.
Other:
• Bathymetry from Oc270 July 1995, Fredrick G Creed
April 1996, Cape Hatteras CH0698, and Onrust
September 1998 cruises available.

Objective
(see text
for details):
|
Determine age of surfaces correlated with sequence
boundaries m1, m4, m5, m5.2, m5.4, m5.6, m5.8, m6,
and o1.
Determine facies of surfaces correlated
with sequence
boundaries.
Determine paleobathymetry of surfaces correlated
with sequence boundaries.
Evaluate facies and age of Paleogene sediments.

Drilling,
coring, and
downhole
measurement
program:
|
Push/rotary core to TD, cased as needed.
High-priority logging suite: total through-pipe gamma ray,
induction resistivity, sonic measurements, magnetic
susceptibility, open-hole spectral and total gamma ray,
mechanical caliper, vertical seismic profiling, in situ
borehole temperature.
Low-priority logging suite: hydrogeological properties,
acoustic imaging (including acoustic caliper).
If VSP proves successful at Site MAT-1 and unsuccessful
at the first hole of Site MAT-2, a second dedicated hole
for VSP may be drilled at Site MAT-2.

Anticipated
lithology:
|
Sediments: medium to coarse sand, possible pebbles
and shell fragments, sandy mudstone, mudstone,
marly chalk, limestone.
Basement: not reached.
