Figure F9. Coherence of sediment properties between widely separated drill sites in the equatorial Pacific is very high, allowing correlation of sediment properties over hundreds of kilometers. Figure shows Sites 1218 and 1219 (Shipboard Scientific Party, 2002), two sites >740 km apart. VGP = virtual geomagnetic pole, GRA = gamma ray attenuation, L* = lightness reflectance value of sediment as defined in the LAB color model. GRA and magnetic susceptibility measurements were completed on board.
