Existence of a permanent benthic fluff layer in the Black Sea basin is suggested, acting as a geochemical transition layer within which all sedimentary particles are hydraulically sorted and particles subject to dissolution or organic remineralization are altered prior to accumulation. We propose that particle residence time within the benthic fluff layer is a key factor in determining sedimentary microfabric and geochemical composition of laminated unit I sediments. We present a schematic model depicting the above relationships and use it to propose a paleoflux scenario for laminae formation in the unit II sapropel. 29.49 41.25 41.35 43.38 35.103333333333346 42.37733333333334 0.0 0.0 not specified KN134-8_Leg1_10 42.09 29.49 Black Sea KN134-8_Leg1 KN134-8_Leg1 1988-03-07T00:00:00 1988-03-07 1988-03-31T00:00:00 1988-03-31 Knorr Fahrt Zeitraum unbekannt Knorr Box corer BC http://en.wikipedia.org/wiki/Box_corer Position estimated from map KN134-8_Leg1_13/14 42.92 31.5 Black Sea KN134-8_Leg1 KN134-8_Leg1 1988-03-07T00:00:00 1988-03-07 1988-03-31T00:00:00 1988-03-31 Knorr Fahrt Zeitraum unbekannt Knorr Box corer BC http://en.wikipedia.org/wiki/Box_corer Position estimated from map KN134-8_Leg1_20 43.04 36.91 Black Sea KN134-8_Leg1 KN134-8_Leg1 1988-03-07T00:00:00 1988-03-07 1988-03-31T00:00:00 1988-03-31 Knorr Fahrt Zeitraum unbekannt Knorr Box corer BC http://en.wikipedia.org/wiki/Box_corer Position estimated from map KN134-8_Leg1_27/28 41.63 40.1 Black Sea KN134-8_Leg1 KN134-8_Leg1 1988-03-07T00:00:00 1988-03-07 1988-03-31T00:00:00 1988-03-31 Knorr Fahrt Zeitraum unbekannt Knorr Box corer BC http://en.wikipedia.org/wiki/Box_corer Position estimated from map KN134-8_Leg1_30 41.35 41.25 Black Sea KN134-8_Leg1 KN134-8_Leg1 1988-03-07T00:00:00 1988-03-07 1988-03-31T00:00:00 1988-03-31 Knorr Fahrt Zeitraum unbekannt Knorr Box corer BC http://en.wikipedia.org/wiki/Box_corer Position estimated from map KN134-8_Leg1_31 42.07 37.24 Black Sea KN134-8_Leg1 KN134-8_Leg1 1988-03-07T00:00:00 1988-03-07 1988-03-31T00:00:00 1988-03-31 Knorr Fahrt Zeitraum unbekannt Knorr Box corer BC http://en.wikipedia.org/wiki/Box_corer Position estimated from map KN134-8_Leg1_36 42.38 31.74 Black Sea KN134-8_Leg1 KN134-8_Leg1 1988-03-07T00:00:00 1988-03-07 1988-03-31T00:00:00 1988-03-31 Knorr Fahrt Zeitraum unbekannt Knorr Box corer BC http://en.wikipedia.org/wiki/Box_corer Position estimated from map KN134-8_Leg1_37 42.04 31.68 Black Sea KN134-8_Leg1 KN134-8_Leg1 1988-03-07T00:00:00 1988-03-07 1988-03-31T00:00:00 1988-03-31 Knorr Fahrt Zeitraum unbekannt Knorr Box corer BC http://en.wikipedia.org/wiki/Box_corer Position estimated from map KN134-8_Leg1_44 42.22 34.1 Black Sea KN134-8_Leg1 KN134-8_Leg1 1988-03-07T00:00:00 1988-03-07 1988-03-31T00:00:00 1988-03-31 Knorr Fahrt Zeitraum unbekannt Knorr Box corer BC http://en.wikipedia.org/wiki/Box_corer Position estimated from map KN134-8_Leg1_47 42.51 37.95 Black Sea KN134-8_Leg1 KN134-8_Leg1 1988-03-07T00:00:00 1988-03-07 1988-03-31T00:00:00 1988-03-31 Knorr Fahrt Zeitraum unbekannt Knorr Box corer BC http://en.wikipedia.org/wiki/Box_corer Position estimated from map KN134-8_Leg1_48 42.59 37.68 Black Sea KN134-8_Leg1 KN134-8_Leg1 1988-03-07T00:00:00 1988-03-07 1988-03-31T00:00:00 1988-03-31 Knorr Fahrt Zeitraum unbekannt Knorr Box corer BC http://en.wikipedia.org/wiki/Box_corer Position estimated from map KN134-8_Leg1_BS 42.16 32.92 Black Sea KN134-8_Leg1 KN134-8_Leg1 1988-03-07T00:00:00 1988-03-07 1988-03-31T00:00:00 1988-03-31 Knorr Fahrt Zeitraum unbekannt Knorr Box corer BC http://en.wikipedia.org/wiki/Box_corer Position estimated from map KN134-8_Leg1_BSK1 43.38 32.04 Black Sea KN134-8_Leg1 KN134-8_Leg1 1988-03-07T00:00:00 1988-03-07 1988-03-31T00:00:00 1988-03-31 Knorr Fahrt Zeitraum unbekannt Knorr Box corer BC http://en.wikipedia.org/wiki/Box_corer Position estimated from map KN134-8_Leg1_BSK2 43.01 34.11 Black Sea KN134-8_Leg1 KN134-8_Leg1 1988-03-07T00:00:00 1988-03-07 1988-03-31T00:00:00 1988-03-31 Knorr Fahrt Zeitraum unbekannt Knorr Box corer BC http://en.wikipedia.org/wiki/Box_corer Position estimated from map KN134-8_Leg1_BSK3 42.27 37.84 Black Sea KN134-8_Leg1 KN134-8_Leg1 1988-03-07T00:00:00 1988-03-07 1988-03-31T00:00:00 1988-03-31 Knorr Fahrt Zeitraum unbekannt Knorr Box corer BC http://en.wikipedia.org/wiki/Box_corer Position estimated from map 284 CC-BY-3.0 Creative Commons Attribution 3.0 Unported https://creativecommons.org/licenses/by/3.0/ Samples were taken in the fluffy layer and inm the underlaing 2 cm sediment.
