Abstract:
This dataset includes pollen data from a peat sequence (named NGBA19) collected at the NGaoundaba peat deposit in 2019. The NGaoundaba peat deposit is located in North East Cameroon (N 7.135°, E 13.690°, 1175 m a.s.l). The 6-meter core was collected using a Russian peat corer. The core was subsampled at 2.5-cm intervals. Pollen analyses were performed on 60 samples. Measurements were performed at the IASCE paleoecology laboratory (University of South Florida). The NGBA19 core covers the last 10 ka (detail on the datation method and results are given in Schaaff et al. (2023, doi:10.1016/j.orggeochem.2023.104589). This dataset is associated to a publication: Sensitivity to climate and vegetation dynamics of a peatland record from Central Cameroon during the African Humid Period (QSR). The publication details the full method used to obtain the data. The study focus on paleoclimatic and paleoenvironmental reconstructions particularly during and after the African Humid Period. Pollen were prepared following standard methods, based on a treatment with 10% KOH followed by pollen retrieval using density separation. Pollen were counted using binocular microscope. Two tablets of Lycopodium sp. spores were added to each sample to allow quantification. Results are given in raw counts.
