This dataset contains raw planktonic foraminifera counts from five sediment cores recovered from the western, central, and eastern North Atlantic Ocean. The dataset includes ODP Site 108-659, located on the Cabo Verde Plateau (18°05′N, 21°02′W; 3070 m water depth), and ODP Site 172-1058, located on the Blake-Bahama Outer Ridge (31°41′N, 75°35′W; 2984 m water depth). It also includes IODP Sites 306-U1312 (42°50.2′N, 23°38.2′W; 3554 m water depth) and 306-U1313 (41°0.08′N, 32°57.4′W; 3426 m water depth), located north of the Azores Islands, and IODP Site 339-U1385, located on the southwest Portuguese margin (37°34.3′N, 10°7.6′W; 2587 m water depth). The combined dataset spans Marine Isotope Stages (MIS) 36 to 46 during the Early Pleistocene. Planktonic foraminiferal assemblages were analyzed in the >150 μm and the 150–250 μm size fraction. Taxonomic counts were performed on splits containing a minimum of approximately 300 specimens per sample. Species identification follows the taxonomic concepts of Schiebel and Hemleben (2017) and the Mikrotax database (Young et al., 2017). Relative abundances (%) were calculated from the total planktonic foraminiferal assemblage for each sample. Age control follows the published chronologies for IODP Site 339-U1385 (Hodell et al., 2023) and ODP Site 172-1058 (Billups et al., 2006; Weirauch et al., 2008). For IODP Site 306-U1312 and ODP Site 108-659, chronologies are based on correlation of benthic δ¹⁸O records of Cibicidoides wuellerstorfi to the LR04 benthic isotope stack, whereas the age model for IODP Site 306-U1313 is based on correlation of the planktonic δ¹⁸O record of Globigerina bulloides to the high-resolution isotope record from IODP Site 339-U1385, which is aligned to the LR04 benthic isotope stack. The dataset provides a standardized compilation of rawplanktonic foraminifera counts from five North Atlantic sites, facilitating comparison of assemblage composition across different oceanographic regions during successive glacial and interglacial intervals of the Early Pleistocene.
