Hyperspectral data of IODP Hole389-M0103A@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. Relative abundance of water, dolomite, aragonite, clay and iron-silicates were logged in 1-cm intervals downcore for each core section and mineral domains interpreted from these results. Further, spectral indices-based carbonate maps were produced for each scanned section. […]本数据集包含国际大洋发现计划（International Ocean Discovery Program, IODP）389次航次（夏威夷淹没礁）指定钻孔的高光谱数据（hyperspectral data），由TheiaX GmbH在该航次的陆上阶段采集。采集工作于2025年2月6日至2025年2月26日在不来梅大学海洋环境科学中心（MARUM – Center for Marine Environmental Sciences, University of Bremen）托管的不来梅岩芯库（Bremen Core Repository, BCR）开展。本次高光谱图像数据采集针对所有归档岩芯半段与选定的岩芯切片，使用配备AisaFENIX高光谱传感器（AisaFENIX hyperspectral sensor）的SisuROCK钻芯扫描仪（Spectral Imaging Ltd., Oulu, Finland，芬兰奥卢光谱成像有限公司）完成，该传感器可覆盖电磁波谱的可见光-近红外（visiblenear-infrared, VNIR）以及短波红外（short-wave infrared, SWIR）波段范围。研究人员以1厘米间隔沿岩芯向下录井，记录了各岩芯段中水、白云石、文石、黏土与铁硅酸盐的相对丰度，并基于上述结果解译出矿物域。此外，还为每个扫描岩芯段生成了基于光谱指数的碳酸盐分布图。[…]
