Seasonal and interannual variability of benthic foraminiferal faunas at 550 m depth in the Bay of Biscay
Abstract Live benthic foraminiferal faunas were sampled 10 times between October 1997 and April 2000 at a 550 m depth open-slope station in the Bay of Biscay. Duplicate cores for 5 samplings allow
The distribution of Mo, U, and Cd in relation to major redox species in muddy sediments of the Bay of Biscay
In order to understand the relationship between authigenic precipitation of U, Mo, Cd, and the redox properties of the marine environment, we have studied the vertical distribution of these metals
Phosphorus diagenesis in sediment of the Thau Lagoon
We describe the depth distribution of phosphorus in relation to the distribution of major redox species (dissolved O2 ,N O 3 ,N H 4 , Mn, and Fe, and particulate S, organic C, reactive Mn- and
Effects of progressive oxygen depletion on sediment diagenesis and fluxes: A model for the lower St. Lawrence River Estuary
We applied a diagenetic model to examine the effects of a decadal-timescale progressive decrease in bottomwater oxygen concentration on sediment geochemistry and fluxes across the sediment–water
The behaviour of arsenic in muddy sediments of the Bay of Biscay (France)
Abstract We have studied particulate and dissolved arsenic species in sediment and porewaters at sites in the Bay of Biscay, France, ranging in depths from 150 to 2,800 m. At all stations, major
Speciation, oxidation state, and reactivity of particulate manganese in marine sediments
Particulate manganese oxides take a significant part in benthic biogeochemical processes of modern marine sediments. Thermodynamics calculations tell us that the reactivity of the different Mn oxides
Live foraminiferal faunas from a 2800 m deep lower canyon station from the Bay of Biscay: Faunal response to focusing of refractory organic matter
A 2800 m deep station was sampled on three occasions, in January 1999, June 1999 and April 2000, in the lower part of Cap-Ferret Canyon (Bay of Biscay). This area is characterisedby a
Early diagenesis of trace metals (Cd, Cu, Co, Ni, U, Mo, and V) in the freshwater reaches of a macrotidal estuary
Vertical profiles from the water column, including the maximum turbidity zone (MTZ) to the consolidated sediment were sampled in September 2000 in the freshwater reaches of the Gironde Estuary during
Recent turbidite deposition in the eastern Atlantic: Early diagenesis and biotic recovery
An interface core taken in Capbreton canyon shows a succession of sedimentary facies interpreted as classical Bouma turbiditic sequences. Activities of 234Th and 210Pb suggest that the deposition of
