Organic geochemistry

Gas analysis was performed on two cores from Hole U1360A using the methods described in “Geochemistry and microbiology” in the “Methods” chapter. Methane concentrations in Cores 318-U1360A-4R and 6R were 118 and 494 ppmv, respectively.

Inorganic geochemistry

Three sediment samples in Hole U1360A were taken for analyses of weight 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 T4.
