Meet the geochemists and microbiologist of Expedition 355! The geochemists look at both the organic and inorganic composition of the cores, collecting information about the water trapped within the sediment (interstitial water), the carbonate content, inorganic and organic carbon content, and nitrogen content. The microbiologists examine the microbial life living in the sediment and rock below the seafloor.
