Figure F29. Color spectral reflectance measurements from split-core surfaces, smoothed with a 20-point moving average, plotted for each hole at Site 1144. L*, a*, and b* are standard parameters calculated by the Minolta CM-2002 photospectrometer from the spectral data. L* = black line, a*/b* = gray line, APC = advanced hydraulic piston corer, XCB = extended core barrel.
