The tops of the Emperor chain guyots, which were drilled during Leg 55, lie above the carbonate compensation depth (CCD), as well as above the foraminiferal dissolution level,...
Alkalinity was determined by Gran titration with an autotitrator (Metrohm 794 basic Titrino) using 0.1 M HCl at 20 degrees C. Report includes alkalinity, correction factor (if applicable), and pH.
Stations ARA-GOF3, ARA-GOF3, ARA-GOF6, ARA-HBP115, ARA-HBP136, ARA-HBP137, ARA-HA2, ARA-LF3 were sampled using rhizons. All other stations were sampled by slicing and centrifugation. Depth 0 m = botto
