Expedition Report, Volume 304/305 Ms 304305-103 Table T12. Lithologic variation of magnetic properties determined from archive-half data, Expedition 304. Notes: Mean = geometric mean with standard deviation (SD) given in log units. Natural remanent magnetization (NRM) values include core sections with residual flux counts. MS = magnetic susceptibility. N = number of samples.
