Pawar, Rahul; Singh, Dharmendra Pratap; Saraswat, Rajeev; Maurya, A S (2026): Orbital forcing regulated Arabian Sea denitrification during the late Pleistocene. Global and Planetary Change, 259, 105373, https://doi.org/10.1016/j.gloplacha.2026.105373
This dataset provides nitrogen isotopic composition (δ¹⁵N) and total nitrogen (TN) measurements from marine sediment core SSD004 GC11 in the southern Arabian Sea covering the last ~167 ka. The records document variability in water-column denitrification, an important control on marine nitrogen cycling and atmospheric N₂O emissions. δ¹⁵N values indicate strong coupling between primary productivity and denitrification during warm intervals, with weaker coupling during cold periods despite continued productivity linked to winter monsoon mixing. ** For all details see the full metadata description at "https://doi.pangaea.de/10.1594/PANGAEA.993903"!
