Disclaimer: This is document is part of a deliverable not yet approved by the European Commission. The file represents the first “EURO-CARBON” full dataset on blue carbon in marine sediments of the European seas, which is described in detailed in the paper Graversen et al. (2025) A marine and salt marsh sediment organic carbon database for European regional seas (EURO-CARBON) Data in Brief Volume 60, June 2025, 111595, https://doi.org/10.1016/j.dib.2025.111595. Errata corrige: please note that the current associated document Zenodo_EURO-CARBON_FullDataset_v1.pdf has one error in the authorship. The author name with affiliation no.50 should be Montserrat Soler, Centro de Estudios Avanzados de Blanes (CSIC-CEAB) ORCID: 0000-0001-5518-8272. Sorry for any inconvenience it may cause. In addition, the dataset EURO-CARBON_Dataset_v1.0 contains some errors and a new version including the changes below is being prepared ASAP (no later than 31 August 2025). In the meantime, we recommend making the following changes before using the database: · The dry bulk density values in the following cells should be removed: 46326-46596 · Entries marked as “Bare sediment” in “Habitat” should be changed to “Seagrass (Zostera marina)”. · Please also add a note indicating whether the Zostera marina beds were sparse or dense: 30554-30562 (Dense); 30563-30572 (Sparse) ; 30581-50588 (Dense); 30589- 30597 (Sparse); 30607-30615 (Dense); 30616-30617 (Sparse); 30627-30630 (Dense); 30631-30639 (Sparse); 30649-30656 (Dense); 30657-30664 (Sparse); 30671-30676 (Dense); 30683-30689 (Sparse); 30690-30696 (Dense); 30697-30703 (Sparse); 30710-30716 (Dense); 30725-30736 (Sparse); 30737-30740 (Dense); 30741-30742 (Sparse); 30743-30744 (Dense); 30751-30756 (Sparse); 30763-30768 (Dense); 30769-30774 (Sparse); 30775-30780 (Dense); 30788-30796 (Sparse); 30797-30803 (Dense); 30810-30815 (Sparse); 30823-30834 (Dense); 30835-30841 (Sparse); 30848-30849 (Sparse); 30850- 30853 (Dense); 30854-30855 (Sparse); 30862-30865 (Sparse); 30866-30869 (Dense); 30876-30882 (Sparse); 30883-30889 (Dense); 30897-30898 (Sparse); 30899-30901 (Dense); 30902-30904 (Sparse); 30910-30914 (Dense); 30915- 30916 (Sparse); 30917-30918 (Dense); 30919-30922 (Sparse); 30929-30934 (Sparse); 30935-30941 (Dense). · Please note that the column of MAR (g/cm2/year) and the associated MAR_se column includes several unit inconsistencies. We recommend not using these columns unless the following corrections are made: 12445-12469: MAR values are reported in g/cm2/ka instead of g/cm2/year; 29652-29765; MAR values are reported in g/m2/year instead of g/cm2/year; 37970-37993: MAR values should be deleted; 38018-38036: MAR values should be deleted; 38095-38118: MAR values should be deleted; 43520-43526: All MAR values in this core should be 0.017g/cm2/year; 43534-43541: All MAR values in this core should be 0.019 g/cm2/year; 43549-43558: All MAR values in this core should be 0.074 g/cm2/year; 43563-43572: All MAR values in this core should be 0.069 g/cm2/year; 48987-50177: MAR values are reported in g/cm2/ka instead of g/cm2/year; 50306-50339: MAR values are reported in g/cm2/ka instead of g/cm2/year; 50434-50534: MAR values are reported in g/cm2/ka instead of g/cm2/year. · Please in 50434-50534 replace the wrong DOI with Correct: https://doi.pangaea.de/10.1594/PANGAEA.55155 Sorry for any inconvenience it may cause.
