Planktic foraminiferal and Ice Rafted Debris (IRD) counts from ODP Site 981

DOI

This dataset contains counts of Neogloboquadrina pachyderma, whole foraminifera and Ice Rafted Debris from ODP Site 981 covering the period 0.95-1.1Ma. Sediment samples from the splice of ODP Site 983 [Jansen et al., 1996] were spun overnight and washed with deionised water through a 6 μm sieve before being dried at 40°C. IRD and foraminiferal counts were made on the >150 μm fraction after splitting to yield approximately 300 entities. IRD was considered as the total number of lithogenic/terrigenous grains counted. Only left coiling specimens of N. pachyderma were counted and all 5 morphotypes of N. pachyderma found in recent Arctic sediments [Eynaud, 2011] were counted.
