Site: MAT-13A

Priority: 2
: 39°12.5'N, 72° 26.6'W
Water Depth:
315 m
Sediment Thickness:
~10 km
Approved Maximum Penetration
: 1049 mbsf
Seismic Coverage:
at the crossing of Ewing 9009 profile 1002 (see Fig. 2 and accompanying seismic lines) and Exxon 75-7

Objectives: The objectives of MAT-13A are to:

1.Augment Neogene upper slope chronostratigraphy acquired as a result of Leg 150 drilling.

2.Sample the expanded and complete Pleistocene section presumed to compose the Hudson Apron, at a point of physical continuity seaward of coeval clinoforms beneath the outer shelf.

3.Calibrate the age and facies of middle Miocene (e.g., m1, m4) and Pleistocene sequence stratigraphic horizons identified to the south beneath the upper slope in the vicinity of Leg 150 sites (Mountain, Miller, Blum et al., 1994).

Drilling Program: Single APC/XCB to refusal, then RCB (after installation of FFF) to TD.

Logging and Downhole Operations: Triple-Combo, FMS-Sonic, Logging While Drilling**, VSP.**

Nature of Rock Anticipated: Sands, silts, and clays; occasional debris flows.
