We recovered a single wash barrel between 0.0 and 145.6 mbsf from Hole 1159A. All four sections (187-1159A-1W-1 through 1W-CC) contain carbonate ooze. The upper 47 cm of Section 187-1159A-1W-1 is fine- to medium-sand-sized globular calcareous microfossils in a slurry of very light brown clay. The remaining core is severely drilling disturbed, mainly very light brown, carbonate-rich clay. The lowermost 23 cm of Section 187-1159A-1W-3 and the core-catcher (CC) section contain densely packed, very light brown calcareous clay with several subtle color changes in varying shades of slightly darker brown clay. Rarely, there are centimeter-thick intervals in which concentrations of abundant microfossils are present, but the contacts of these layers are disrupted by drilling. Three pieces of aphyric basalt were recovered in the lowermost part of Section 187-1159A-1W-CC.
