Organic geochemistry

Gas analysis was performed on three cores in Hole U1358B using the methods described in “Geochemistry and microbiology” in the “Methods” chapter. Methane concentrations in the three cores were statistically insignificant (≤2 ppmv).

Inorganic geochemistry

Three sediment samples in Hole U1358B were taken for analyses of percent carbonate and major and trace element analyses (silicon, titanium, aluminum, iron, calcium, magnesium, sodium, potassium, phosphorus, strontium, barium, vanadium, scandium, and cobalt). Data are reported in Table T5.
