The Sea\u2019s oxygen inventory depends on vertical mixing that transports dissolved oxygen (DO) from the upper euphotic layer to deeper layers and on dissolved oxygen consumption for the oxidation of organic matter (OM) and reduced species of S, Fe, and Mn. Here we use a vertical one-dimensional transport model, 2DBP, forced by Copernicus data, that was coupled with the FABM-family N-P-Si-C-O-S-Mn-Fe Bottom RedOx Model BROM. The research objective of this study was to analyze the oxygen budget in the upper 350 m of the Sea and demonstrate the role of the parameterization of the acceleration of the sinking of particles covered by precipitated Mn(IV). The analysis of the oxygen budget revealed distinct patterns in oxygen consumption within different depths. In the oxic zone, the primary sink for DO is the mineralization of organic matter, whereas in the suboxic zone, dissolved Mn(II) oxidation becomes the predominant sink. The produced Mn(IV) sinks down and reacts with hydrogen sulphide several meters below, making possible the existence of the suboxic layer without detectable concentrations of DO and H2S.<\/jats:p>","DOI":"10.3390\/w16172380","type":"journal-article","created":{"date-parts":[[2024,8,26]],"date-time":"2024-08-26T03:14:31Z","timestamp":1724642071000},"page":"2380","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Model-Based Analysis of the Oxygen Budget in the Black Sea Water Column"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3124-3702","authenticated-orcid":false,"given":"Matvey","family":"Novikov","sequence":"first","affiliation":[{"name":"Shirshov Institute of Oceanology, Russian Academy of Sciences, Nakhimovskiy Prosp. 36, 117991 Moscow, Russia"}]},{"given":"Svetlana","family":"Pakhomova","sequence":"additional","affiliation":[{"name":"Norwegian Institute for Water Research (NIVA), Gaustadall\u00e9en 21, 0349 Oslo, Norway"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9356-8807","authenticated-orcid":false,"given":"Anfisa","family":"Berezina","sequence":"additional","affiliation":[{"name":"Norwegian Institute for Water Research (NIVA), Gaustadall\u00e9en 21, 0349 Oslo, Norway"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5008-9611","authenticated-orcid":false,"given":"Evgeniy","family":"Yakushev","sequence":"additional","affiliation":[{"name":"Norwegian Institute for Water Research (NIVA), Gaustadall\u00e9en 21, 0349 Oslo, Norway"}]}],"member":"1968","published-online":{"date-parts":[[2024,8,24]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2287","DOI":"10.1016\/j.ecolmodel.2010.06.007","article-title":"Carbon, nitrogen, oxygen and sulfide budgets in the Black Sea: A biogeochemical model of the whole water column coupling the oxic and anoxic parts","volume":"221","author":"Soetaert","year":"2010","journal-title":"Ecol.
