Freshwater ostracode and pollen data of sediment core PI-6 (85 ka BP) from Lake Petén Itzá, Guatemala (ICDP-2004/03)

The composite sediment sequence from three holes was recovered from a water depth of 71 m, and subsampled every ~ 20 cm for biological analysis. Our ostracode data (adults and juveniles) includes information on species abundances and richness, diversity index, DCA species scores along the first two DCA axes, stratigraphic DCAs (axes 1 and 2), ecological change and rates of ecological change.

The following pollen data are provided as well: Taxa richness, diversity (pollen sum), DCA taxa scores along the first two DCA axes, stratigraphic DCAs (axes 1 and 2), ecological change and rates of ecological change.
