Porewater and solid phase geochemical data at two contrasting NE Atlantic stations are
reported. Station 10552, on the Cape Verde abyssal plain, is a site of slow pelagic …

Sediment cores up to 35 m long have been recovered from turbidite sequences in the
Madiera Abyssal Plain and the Southern Nares Abyssal Plain. Detailed geochemical …

In two distal carbonate turbidites (labelled a and e) from the Madeira Abyssal Plain oxidation

STEADYSED1 is a multicomponent reactive transport code for steady-state early diagenesis
which fully incorporates the reaction couplings among the elements, C, O, N, S, Fe, and Mn …

Porewaters recovered from sediment cores (gravity corers, box corers, and multicorers) from
various subrogions of the South Atlantic (Amazon River mouth, equatorial upwelling, Congo …

Pore water profiles of total-CO 2, pH, PO 3− 4, NO− 3 plus NO− 2, SO 2− 4, S 2−, Fe 2+ and
Mn 2+ have been obtained in cores from pelagic sediments of the eastern equatorial Atlantic …

Sediments deposited on the Madeira Abyssal Plain (MAP) during the late Quaternary consist
of an alternating succession of distal turbidites and pelagites. Individual turbidites may be …

Measured pore-water concentrations of iron in interbedded pelagic and turbiditic sediments
from the Nares Abyssal Plain are in excellent agreement with sediment colour and …

A set of oxidized and unoxidized sediment intervals from the f-turbidite identified in two
piston cores from the Madeira Abyssal Plain (MAP) was analyzed for calcium carbonate …

Chemical reactions in marine sediments and the resulting fluxes across the sediment-water
interface influence the global carbon cycle and the pH of the sea and affect the abundance …
