20.500.12556/DiRROS-18945 A global database of dissolved organic matter (DOM) concentration measurements in coastal waters (CoastDOM v1) Measurements of dissolved organic carbon (DOC), nitrogen (DON), and phosphorus (DOP) concentrations are used to characterize the dissolved organic matter (DOM) pool and are important components of biogeochemical cycling in the coastal ocean. Here, we present the first edition of a global database (CoastDOM v1; available at https://doi.org/10.1594/PANGAEA.964012, Lønborg et al., 2023) compiling previously published and unpublished measurements of DOC, DON, and DOP in coastal waters. These data are complemented by hydrographic data such as temperature and salinity and, to the extent possible, other biogeochemical variables (e.g. chlorophyll a, inorganic nutrients) and the inorganic carbon system (e.g. dissolved inorganic carbon and total alkalinity). Overall, CoastDOM v1 includes observations of concentrations from all continents. However, most data were collected in the Northern Hemisphere, with a clear gap in DOM measurements from the Southern Hemisphere. The data included were collected from 1978 to 2022 and consist of 62 338 data points for DOC, 20 356 for DON, and 13 533 for DOP. The number of measurements decreases progressively in the sequence DOC > DON > DOP, reflecting both differences in the maturity of the analytical methods and the greater focus on carbon cycling by the aquatic science community. The global database shows that the average DOC concentration in coastal waters (average ± standard deviation (SD): 182±314 µmolC L−1; median: 103 µmolC L−1) is 13-fold higher than the average coastal DON concentration (13.6 ± 30.4 µmol N L−1; median: 8.0 µmol N L−1), which is itself 39-fold higher than the average coastal DOP concentration (0.34 ± 1.11 µmol P L−1; median: 0.18 µmol P L−1). This dataset will be useful for identifying global spatial and temporal patterns in DOM and will help facilitate the reuse of DOC, DON, and DOP data in studies aimed at better characterizing local biogeochemical processes; closing nutrient budgets; estimating carbon, nitrogen, and phosphorous pools; and establishing a baseline for modelling future changes in coastal waters. global database dissolved organic matter coastal waters marine biology globalna podatkovna zbirka raztopljena organska snov obalne vode morska biologija true false false Angleški jezik Slovenski jezik Neznano 2024-05-17 09:50:36 2024-05-17 09:50:37 2024-05-23 11:41:04 0000-00-00 00:00:00 2024 0 0 Slovenski soavtorici: Katja Klun, Tinkara Tinta; str. 1107–1119 iss. 2 Vol. 16 2024 0000-00-00 Zaloznikova Objavljeno apc 0000-00-00 0000-00-00 2024-02-27 574 1866-3516 10.5194/essd-16-1107-2024 188455939 https://doi.org/10.5194/essd-16-1107-2024 1 26eeb1b6-1422-11ef-9c9e-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=25969 RAZ_Lonborg_Christian_2024.pdf RAZ_Lonborg_Christian_2024.pdf 1 34D82B1080B506B864292F67128FC414 b468619dfbced02d9130117f4fca0d416ce000cd9110a6c2aec569389d00ee9c 95a6632d-1423-11ef-9c9e-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=25970 Nacionalni inštitut za biologijo 0 0 0
