Hyperspectral data of individual slab samples from IODP Hole 389-M0106B@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. […]本数据集为国际大洋发现计划（International Ocean Discovery Program, IODP）389航次（夏威夷淹没礁）上述指定钻孔的高光谱数据，由TheiaX GmbH公司在该航次的陆上阶段采集。该航次陆上阶段于2025年2月6日至2月26日，在不来梅大学海洋环境科学中心（MARUM）托管的不来梅岩芯库（Bremen Core Repository, BCR）内开展。 本次高光谱图像数据采集覆盖所有归档岩芯半段及选定的岩芯板样，采用芬兰奥卢市Spectral Imaging有限公司生产的SisuROCK岩芯扫描系统完成，该系统搭载AisaFENIX高光谱传感器，可覆盖电磁波谱的可见光-近红外（Visible and Near-Infrared, VNIR）及短波红外（Short-Wave Infrared, SWIR）波段范围。 除对每个岩芯段开展常规扫描外，本次研究还对单个古气候珊瑚板样进行了扫描，并为每个板样生成了基于光谱指数的碳酸盐分布图。[……]
