Abstract:
This dataset comprises paleoceanographic reconstructions from KNR158-4-09GGC using multiple proxies, including coarse fraction percentage; planktonic foraminifera abundance (shown as % Neogloboquadrina pachyderma); sortable silt grain size data (analysed on both a Beckman Coulter Multisizer 4 using the Enhanced Performance Multisizer 4 beaker and stirrer setting 30 for full sediment suspension and a Malvern Mastersizer 2000 at University College London) and inferred flow speed.
