Abstract:
Bulk sediment U-series measurements in the core TR163-25 over the last deglaciation. Used in the study 'Alkalinity cycling rapidly buffers deep ocean pH during the last glacial cycle' (Trudgill, publication year) to reconstruct authigenic uranium and assess oxygen concentration changes, and to calculate a 232Th normalised sediment flux.
