Reconstructing changes in seep activity by means of pore water and solid phase Sr/Ca and Mg/Ca ratios in pockmark sediments of the Northern Congo Fan
K Nöthen, S Kasten - Marine Geology, 2011 - Elsevier
This study focuses on the vertical distribution of authigenic carbonates (aragonite and high
Mg-calcite) in the form of finely disseminated precipitates as well as massive carbonate …

Lateral transport controls distribution, quality, and burial of organic matter along continental slopes in high-productivity areas
In this study we demonstrate the relevance of lateral particle transport in nepheloid layers for
organic carbon (OC) accumulation and burial across high-productive continental margins …

Benthic carbon mineralization on a global scale
In this study we present a global distribution pattern and budget of the minimum flux of
particulate organic carbon to the sea floor (JPOCα). The estimations are based on regionally …

Benthic foraminifera off West Africa (1° N to 32° S): Do live assemblages from the topmost sediment reliably record environmental variability?
L Licari, A Mackensen - Marine Micropaleontology, 2005 - Elsevier
Recent benthic foraminifera (> 125 μm) were investigated from multicorer samples on a
latitudinal transect of 20 stations between 1° N and 32° S along the upper slope off West …

Fluxes of soot black carbon to South Atlantic sediments
Deep sea sediment samples from the South Atlantic Ocean were analyzed for soot black
carbon (BC), total organic carbon (TOC), stable carbon isotope ratios (δ13C), and polycyclic …

New insights on black carbon in pelagic Atlantic sediments
Black carbon (BC) is ubiquitous in pelagic sediments and presumed to have an older
radiocarbon age due to long ocean residence times and pre-aging in terrestrial soils. Here …
