Figure F28. Color spectral reflectance measurements from split-core surfaces at Site 1148 smoothed with a 20-point moving average, plotted for each hole. L*, a*, and b* are standard parameters calculated by the Minolta CM-2002 photo spectrometer from the spectral data. L* = black line, a*/ b* = gray line, APC = advanced hydraulic piston corer, XCB = extended core barrel.
