Figure F4. A comparison of shipboard VGP (virtual geomagnetic pole) latitude from shipboard paleomagnetics to those from the U-channel splice made postcruise (after Lanci et al., 2004). Data are from lower Miocene sediments of Site 1218. Although the shipboard paleomagnetic record was good, postcruise U-channel studies allowed the search for paleomagnetic events with lifetimes <20 k.y.
