(2024): Sedimentological and remote sensing data from the reef island Langkai, Spermonde Archipelago, Indonesia [dataset bundled publication]. PANGAEA, https://doi.org/10.1594/PANGAEA.967719 The data set includes radiocarbon ages of sediments from the reef island Langkai, SW Sulawesi, Indonesia. The data was collected in order to reconstruct the Holocene and modern (sediment) dynamics over the past ca 6,000 years. Sediment samples were obtained from sediment cores taken by percussion drilling and hand-held (Auger) coring in May 2016 and July 2021. Laboratory analysis of the sediments and shoreline analysis were carried out between 2021 and 2023. In bulk sediment samples, a total of 20 radiocarbon ages from AMS dating were calibrated using OxCal online v4.4 (Bronk Ramsey, 2009), with the MARINE20 curve (Heaton et al., 2020) and a regional reservoir correction of deltaR= 0+-0 as suggested by Southon et al. (2002). 16360 https://doi.org/10.1594/PANGAEA.965855 2024-05-13T09:32:29+0000 2024 15141 15264 15251 19946 19944 15169 15250 19292 20575 14209 14181 19291 14236 14046 20585 20586 20587 20588 20589 20590 20593 20596 20598 20600 20605 20609 20612 20616 20621 20576 19645 19646 19644
