Hyperspectral data of individual slab samples from IODP Hole 389-M0100A@en

Hyperspectral data from the above given hole of International Ocean Discovery Program (IODP) Expedition 389 (Hawaiian Drowned Reefs) acquired by TheiaX GmbH during the onshore phase of the expedition, which was held between 2025-02-06 to 2025-02-26 at the Bremen Core Repository (BCR) hosted at MARUM – Center for Marine Environmental Sciences, University of Bremen. Acquisition of hyperspectral image data took place on all Archive halves and selected core slabs using a SisuROCK drill-core scanner (Spectral Imaging Ltd., Oulu, Finland) equipped with an AisaFENIX hyperspectral sensor to cover the visible and near-infrared (VNIR) as well as short-wave infrared (SWIR) regions of the electromagnetically spectrum. In addition to the routine scans of each core section, individual paleoclimate coral slab samples were scanned and spectral indices-based carbonate maps produced for each individual slab sample. […]本数据集包含高光谱数据（hyperspectral data），采集自国际大洋发现计划（International Ocean Discovery Program, IODP）第389次航次（夏威夷淹没礁）指定钻孔，由TheiaX GmbH公司在该航次陆上科考阶段完成采集；本次陆上科考时段为2025年2月6日至2025年2月26日，采集地点设于不来梅大学海洋环境科学中心（MARUM – Center for Marine Environmental Sciences, University of Bremen）托管的不来梅岩心库（Bremen Core Repository, BCR）。本次高光谱图像数据采集覆盖所有归档岩心半段与选定的岩心板片，采用搭载AisaFENIX高光谱传感器的SisuROCK岩心扫描钻机完成，设备由芬兰奥卢市光谱成像有限公司（Spectral Imaging Ltd., Oulu, Finland）制造，扫描光谱范围涵盖电磁频谱的可见光-近红外（visible and near-infrared, VNIR）与短波红外（short-wave infrared, SWIR）波段。除对每个岩心段开展常规扫描外，研究团队还对单独的古气候珊瑚板片样品进行了扫描，并为每块板片样品生成了基于光谱指数的碳酸盐分布图。[…]
