PANGAEA, https://doi.pangaea.de/10.1594/PANGAEA.993811 (DOI registration in progress) Abstract: Pollen data from Tarn 2, Mt. Usborne, East Falkland extracted from tar2-18-1 with piston corer in Spring 2018. Data is plotted by depth of the piston core and age. Pollen assemblage is reported as raw counts, percentage of the upland sum (%), pollen concentration (grains/cm3), and pollen accumulation rate (grains/cm2/yr).
