The dataset consists of the total abundance of planktic foraminifera, the relative abundances of planktic foraminiferal species, and planktic and benthic oxygen and carbon stable isotope ratios of the uppermost 18.5 cm of gravity core OCE2017-GR02-GC. The core was retrieved from a plateau on the northeastern Greenland continental slope (77º05'11 N, 5º19'53 W, 1200 m water depth) during an expedition of R/V Oceania in August 2017. Here we present the record from the uppermost 18.5 cm of the total 135 cm of core length. The core was sampled at 0.5 cm intervals in the uppermost 10.5 cm and at 2 cm intervals in the remaining part. Samples were freeze-dried, weighed, wet-sieved through a 63 μm sieve, and subsequently split into size fractions using 100 and 500 μm sieves. Counts of planktic foraminiferal assemblages were conducted on representative splits (>300 specimens) of the 100–500 μm size fraction. Individual species were identified and counted. The number of planktic foraminifera per 1 g dry sediment as ...
