This data set contains summary descriptions (JPEG) for the 20 cores collected in 2008 on the R/V Seward Johnson during field activity 2008-008-FA. These descriptions were created in LogPlot 7 and represent descriptive core information including: color, lithology, samples taken, mean grain-size, grain-size distribution, wet bulk density, and magnetic susceptibility.
