Notes: * = as mM chloride = chlorinity (%) x 1.0243/35.453 x 1000. † = calculated by charge balance, cations = anions. ‡ = water sample obtained from split core 1-2 days after core was taken and could be contaminated with drill fluid (surface water). Only a portion of this table appears here. The complete table is also available in ASCII.
