Gershanovich David E Zinkovskiy Alexander B 1987 Distribution of particulate matter and particulate organic carbon in waters of the Caspian Sea dataset https://doi.org/10.1594/PANGAEA.756520 Gershanovich David E Zinkovskiy Alexander B 1987 New data on suspended material in the Caspian Sea journal article Oceanology 27(1) 72-78 Data on concentrations and distribution of particulate matter in the Caspian Sea obtained during surveys in 1981-1983 with use of modified filtering units have shown that over the major part of the sea concentration of particulate matter does dot exceed 1-2 mg/l. Only in the northern Caspian and in coastal regions concentrations correspond to values measured earlier. Total amount of particulate matter in the Caspian Sea is about of 90 million ton, 19.6% in the Northern Caspian, 28.1% in the Middle Caspian, and 52.3% in the Southern Caspian. Contents of carbon in particulate matter of the Central Caspian reach 30-40%, and over a significant part of the sea - 20%. A correlation has been found between areas of increased carbon contents in particulate matter and in bottom sediments. An important role of biofiltration in enrichment of particulates in organic matter has been noted. From data on carbon contents and an estimate of particulate matter input biogenic portion in particulate matter exceeds 50% for the whole sea. 47.55 51.89 38.17 45.18 50.191250000000004 41.06374999999999 0.0 800.0 vertical profile ARCOD Archive of Ocean Data Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research, Bremerhaven AWI https://www.awi.de/ https://ror.org/032e6b942 Casp-81-83-2 43.86 48.53 -25.0 Caspian Sea Water sample WS Casp-81-83-8 44.21 50.36 -20.0 Caspian Sea Water sample WS Casp-81-83-31 42.57 49.72 -543.0 Caspian Sea Water sample WS Casp-81-83-37 41.84 49.48 -705.0 Caspian Sea Water sample WS Casp-81-83-38 42.0 49.92 -770.0 Caspian Sea Water sample WS Casp-81-83-39 42.41 50.75 -606.0 Caspian Sea Water sample WS Casp-81-83-48 41.95 50.91 -436.0 Caspian Sea Water sample WS Casp-81-83-49 40.82 49.83 -73.0 Caspian Sea Water sample WS Casp-81-83-49a 41.67 50.44 -748.0 Caspian Sea Water sample WS Casp-81-83-50 41.51 50.01 -603.0 Caspian Sea Water sample WS Casp-81-83-52 41.18 51.05 -335.0 Caspian Sea Water sample WS Casp-81-83-54 41.4 51.89 -105.0 Caspian Sea Water sample WS Casp-81-83-58 41.09 51.18 -348.0 Caspian Sea Water sample WS Casp-81-83-68 39.54 50.3 -708.0 Caspian Sea Water sample WS Casp-81-83-70 39.56 51.39 -658.0 Caspian Sea Water sample WS Casp-81-83-70a 44.16 48.2 -10.0 Caspian Sea Water sample WS Casp-81-83-77 38.96 49.64 -305.0 Caspian Sea Water sample WS Casp-81-83-77a 45.18 47.55 -3.5 Caspian Sea Water sample WS Casp-81-83-79 38.97 50.49 -805.0 Caspian Sea Water sample WS Casp-81-83-80 38.99 51.08 -655.0 Caspian Sea Water sample WS Casp-81-83-86 38.65 49.34 -325.0 Caspian Sea Water sample WS Casp-81-83-88 38.47 50.14 -805.0 Caspian Sea Water sample WS Casp-81-83-90 38.37 50.67 -808.0 Caspian Sea Water sample WS Casp-81-83-92 38.17 51.72 -148.0 Caspian Sea Water sample WS 176 CC-BY-3.0 Creative Commons Attribution 3.0 Unported https://creativecommons.org/licenses/by/3.0/ Event label Event Event Latitude of event Latitude Latitude Longitude of event Longitude Longitude Elevation of event Elevation m Elevation [m] DEPTH, water Depth water m depth http://purl.obolibrary.org/obo/PATO_0001595 water http://purl.obolibrary.org/obo/CHEBI_15377 Length L http://dbpedia.org/resource/Length Depth water [m] Total particulate matter TPM mg/l Density http://dbpedia.org/resource/Density Filtration Gershanovich David E TPM [mg/l] Carbon, organic, particulate POC µg/l carbon C https://www.ebi.ac.uk/chebi/searchId.do?chebiId=CHEBI:27594 organic particulate Density http://dbpedia.org/resource/Density Wet combustion Gershanovich David E POC [µg/l] Carbon C % carbon C https://www.ebi.ac.uk/chebi/searchId.do?chebiId=CHEBI:27594 Dimensionless Ratio ψ Carbon/nitrogen analyser Chemical property sensors elemental analysers http://vocab.nerc.ac.uk/collection/L05/current/LAB01/ Gershanovich David E C [%] supplement citable author37773 author37774 event2620902 event2620903 event2620904 event2620905 event2620906 event2620907 event2620908 event2620909 event2620910 event2620911 event2620912 event2620913 event2620914 event2620915 event2620916 event2620917 event2620918 event2620919 event2620920 event2620921 event2620922 event2620923 event2620924 event2620925 geocode1600 geocode1601 geocode1619 geocode8128 inst32 journal12199 license101 method11785 method193 method4909 method533 param23995 param768 param80167 pi37773 project4026 ref33572 term1073131 term2299468 term2606205 term26945 term38338 term38477 term43792 term43794 term43863 term44419 term67625 topotype3
