By considering the Ac/Al and S/G ratios together (Figure ), the effects of different environments on English Oak can be summarized. This sample set contains a source sample (modern oak); samples from working vessels in marine environments (SB Tollesbury and HMS Unicorn); and samples from conserved vessels in dry dock (HMS Victory, Mary Rose). Their paths to dry dock differed: HMS Victory went directly from being a working vessel to conservation in dry dock, while Mary Rose spent centuries under the seabed before being conserved in dry dock. Considering Figure , the Mary Rose core sample stands out as having both a low S/G ratio and low Ac/Al ratios. This indicates that this sample has potentially experienced different processes.
