Grain size analysis of sediments from the reef island Barrang Lompo, Spermonde Archipelago, Indonesia@en

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 processed grain size data using GRADISTAT by Blott & Pye (2001). The collected data provides information of reef-derived sedimentation in the Holocene in the Spermonde Archipelago.本数据集取材自东南亚苏拉威西（Sulawesi）斯佩蒙德群岛（Spermonde Archipelago）巴朗隆波礁岛（Barrang Lompo）的50份软质碳酸盐沉积物样品。该岛上的5个取芯点位通过冲击钻探获取了地下沉积物样品。每个取芯点位以1米为间隔采集10份样品，因此每个点位可获取地表以下最大深度10米的样品（1米、2米……10米）。实验室数据的采集时段为2019年至2021年。本数据集包含由Blott与Pye（2001）开发的GRADISTAT软件处理得到的粒度数据。所采集的数据可用于解析斯佩蒙德群岛全新世时期的礁源沉积过程。
