Hyperspectral data of IODP Hole389-M0104A
No full textHyperspectral 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.

TEX86 SST analysis from ODP Site 133-820 in the Coral Sea between MIS 22-MIS 1
No full textIn this data set, we present a new biomarker, sea surface temperature (SST) reconstructions from ODP site 820. ODP site 820 is from the Coral Sea, located next to the Great Barrier Reef. In this data set, we use TEX86 to reconstruct SSTs from MIS 22- MIS 1. In the data we include both the raw GDGT data, the TEX86, and indices. Also included are replicates for all the biomarker data. Finally, we include information on SST values that were later rejected because of issues with the indices. We also updated the age model using revised biostratigraphic data and tuning. In doing so we show that SSTs increased around MIS 17 at the same time as records show the development of the Great Barrier Reef. The data is published in the following article: Petrick, Benjamin, Lars Reuning, Alexandra Auderset, Miriam Pfeiffer, Gerald Auer, and Lorenz Schwark. 2024. "High Sea Surface Temperatures Were a Prerequisite for the Development and Expansion of the Great Barrier Reef." Science Advances 10 (49): eado2058. doi:10.1126/sciadv.ado205
XRF geochemistry of sediment core SO121_KL42, southern Red Sea
No full textWe present high-resolution XRF geochemical data from the upper 8.30 m of marine sediment core KL42, southern Red Sea. The core was recovered at 15°54.9' N and 41°34.7' E from a water depth of 958 m during RV Sonne cruise SO121 in 1997. The data were collected with an ITRAX (Cox Analytical Systems) X-ray fluorescence (XRF) core scanner. The scanner was equipped with a Cr-tube running with a tube voltage of 30 kV and a tube current of 55 mA. The exposure time was 5 ms per measurement and the scanning interval was 0.2 cm
Hyperspectral tundra traits: 20 EnMAP-based plant functional traits of Arctic tundra communities
No full textWith this dataset, we provide raster data containing 20 predicted plant functional traits based on EnMAP imagery from 2022 to 2024 in the Arctic biome. The traits were predicted based on a convolutional neural network created by Cherif et al. (2023) and adapted specifically to EnMAP data by Mederer et al. (2025). We used all available EnMAP tiles during the vegetation periods from 2022 until 2024 that were obtained in the Arctic region. However, due to the targeted observation scheme of the EnMAP mission, the tiles mainly cover regions on the North American continent and Greenland. Each raster file (in .tif- format) contains 20 layers, one layer per predicted plant trait. A water mask based on NDVI < 0.1 has been applied to all scenes. For further details on model architecture the user is referred to the above mentioned publications. The data was collected in order to assess ecosystem functional diversity and classify land cover types in a trait-based framework across the Arctic biome. It can be further used for mapping purposes, including the distribution of plant functional types. The data can be paired with field spectroscopy for upscaling approaches as well as for fusion with imagery from other sensor types. For now, this dataset can be considered a preliminary version. Meanwhile, the model for trait prediction is being under further development to address the specific requirements of Arctic vegetation for trait predictions from hyperspectral data
