On board Leg 199, LAS-based mineralogy was determined on the moisture and density (MAD) samples as well as an additional one sample per section (located ~75 cm from the MAD sample). It is our hope that these data will prove useful to other shipboard scientists such as the sedimentologists and stratigraphic correlators. The second goal for determining LAS-based mineralogy is to calculate MARs, which in turn contribute to the overall objective of paleoclimate reconstruction. Further postcruise research will also involve improved algorithms, which will lower the percent error for individual samples.
