Notes: * = Shipboard measurement (Binns, Barriga, Miller, et al., 2002). † = blank samples are composed of deionized water acidified as for borehole samples. DL = instrumental detection limit (in italics). ICP–AES = inductively coupled plasma–atomic emission spectroscopy, ICP–MS = inductively coupled plasma–mass spectroscopy, ND = not detected, NA = not analyzed, OR = over instrument range.
