anonymous 16352 Raw grain sizes of sediments from the reef island Barrang Lompo, Spermonde Archipelago, Indonesia The dataset is based on 50 soft carbonate sediment samples from the reef island Barrang Lompo in the Spermonde Archipelago, Sulawesi, SE Asia. The subsurface samples were obtained by percussion drilling at 5 coring locations on the island. From each coring location, 10 samples were retrieved in 1 m intervals, thus providing samples from a maximum depth of 10 m below surface at each site (1 m, 2 m, ..., 10 m). Laboratory data was collected between 2019 and 2021. The provided dataset contains raw grain sizes determined after dry sieving. Samples were weighed before sieving (initial mass). After sieving, fractions (diameters from 32 mm to 0.0063 mm) from each sieve were weighed to analyze grain size distribution. The collected data provides information of reef-derived sedimentation in the Holocene in the Spermonde Archipelago. 16360 https://doi.org/10.1594/PANGAEA.954702 2023-01-20T15:50:25+0000 2023 19292 14046 19291 18779 19290 14236 14209 19289 19288 19287 19286 19285 19649 19648 19645 19647 19646 19644 16375 Kappelmann, Yannis; Westphal, Hildegard; Kneer, Dominik; Wu, Henry C; Wizemann, Andre; Jompa, Jamaluddin; Mann, Thomas (2023): Raw grain sizes of sediments from the reef island Barrang Lompo, Spermonde Archipelago, Indonesia [dataset].
