Figure F30. Plot of loss on ignition (LOI) compared with total H2O and CO2 for samples analyzed during Expedition 335. Values for LOI are most likely minimum values because of the effects of iron oxidation, whereas water values are most likely overestimates because of the overlap between water and S peaks (see the “Methods” chapter [Expedition 335 Scientists, 2012b]). C = cored samples, JB = samples retrieved during junk basket runs.
