Notes: Lithology and degree of alteration from shipboard core description (cf Fig. F20 in the "Site U1301" chapter). BET = Brunauer, Emmett, and Teller. SSA = specific surface area, SD = standard deviation, RSD = relative standard deviation, N = number of replicates. Blank cells = no measurements were made.
