Additionally, deglacial benthic foraminifera assemblage data are reported from site SHAK-05-3K. Stable oxygen and carbon isotopes were performed on the planktic foraminifer species Globigerina bulloides from the 250-300μm size fraction in the Godwin Laboratory, University of Cambridge. Benthic foraminiferal census counts were conducted on specimens picked from the >212μm size fraction. A smaller subset of samples from site SHAK-05-3P was analysed for benthic foraminifera assemblages using the >150μm size fraction.-10.6918-10.06330000000002737.602537.7817Natural Environment Research Councilhttps://doi.org/10.13039/5011000002702073288PhD studentship
