Sedimentary Transport Influences on Diagenetic Processes at the Amazon Continental Shelf, Brazil

Modeling Sedimentary Deposits on the Continental Margin

A first objective is to investigate the fabric (pattern) of seabed stratification on continental margins at small time and space scales (1 cm-50 cm depth into the seabed; 1 hr-3 yrs sedimentary record). To this end, we are testing the hypothesis that on muddy shelves such as the northern California shelf, Holocene event stratigraphy consists of the deposits of high-concentration storm regimes a...

Drilling Productivity on the Norwegian Continental Shelf

Recently, we have seen falling oil prices combined with sticky costs at a high level in the petroleum industry. This cause cost cuts and project postponements, thus challenging reserve replacement of oil companies and security of supply for consumers. Costs are particularly high for drilling. High rig rates are obviously important. In new contracts for high-spec semi rigs on the Norwegian Conti...

Net Heterotrophy in the Amazon Continental Shelf Changes Rapidly to a Sink of CO2 in the Outer Amazon Plume

The Amazon continental shelf and adjacent oceanic area were sampled for inorganic and organic carbon parameters in order to improve data coverage and understanding of carbon cycling dynamics within this important region. Seasonal coverage of the Amazon plume on the French Guiana continental shelf further north, was provided by CO2 monitoring using a merchant ship sailing from France to French G...

Riverine Carbon and the Sedimentary Record on the Continental Shelves

The field work is carried out in the northern Adriatic margin in the framework of the EuroSTRAFORM program. Our approach is to use the signature of the organic matter in order to: 1) trace the initial distribution of flood sediments on the shelf (spatial variability); 2) trace the physical and biological reworking of the flood layer (temporal variability); 3) discriminate between Po and Apennin...
