This data set presents the palynological row data performed on sediment samples from the ODP Hole 882A (50°21.79'N, 167°35.99'E, 3244 m) drilled on the Detroit Seamount in the northern part of the Hawaiian-Emperor Seamount Chain in the North Pacific Ocean during the Plio-Pleistocene. A total of 44 samples were analyzed for their palynological contents using a transmitted light microscope at 250× to 1000× magnification. The palynomorphs analyzed included dinocysts, acritarchs, pollen grains, spores and other palynofacies. In the study sequence, the assemblages are characterized by 33 dinocyst species, 2 acritarch taxa, 8 pollen morphotypes. Row counts are shown (number of identified specimens), as well as labels, depth (in mcd) and estimated age (Ma) of the studied samples.
