Abstract:
Stable isotope composition of G. affinis and C. wuellerstorfi in the core TR163-25. Data covers the last glacial cycle and is used to reconstruct bottom water oxygen concentrations. It is paired with carbonate system reconstructions to reconstruct ocean alkalinity in the publication 'Alkalinity cycling rapidly buffers deep ocean pH during the last glacial cycle' (publication year) and asses the drivers of ocean alkalinity cycling.
