Supplementary Data | Global patterns and drivers of nitrogen isotope signal in modern marine sediments

This dataset compiles elemental and isotopic data from seafloor sediments and sediment cores across globally distributed marine sites. It includes sampling information, organic carbon [OC], total nitrogen [TN], OC/N ratios, inorganic nitrogen [IN] and organic nitrogen [ON] content, δ¹³Corg, bulk nitrogen isotope [δ¹⁵N-Bulk], ON isotope [δ¹⁵N-ON], IN isotope [δ¹⁵N-IN], centennial-scale change rates in sedimentary δ¹⁵N and nitrogen content/accumulation, and reconstructed trends over the past century. For full methodological details, consult the publications referenced below the tables. This study reconstructs global spatiotemporal variations in δ¹⁵N from modern marine sediments to advance understanding of nitrogen cycling in contemporary ocean systems.
