Sediment samples from the Ocean Drilling Program Site 976 (36°12.3'N, 4°18.8'W) were processed for palynological analyses to reconstruct past vegetation dynamics in the southwestern Mediterranean region during the Penultimate Glacial (MIS 6). Raw pollen counts are provided for a time interval between 190 and 127 ka. The age model is based on correlation with the temperate pollen profile from core MD01-2444 from the Portuguese margin (Margari et al., 2010), and with Dongge cave speleothem (Charton et al., 2026; Jiménez-Amat and Zahn, 2015; Kelly et al., 2006).
