Geological carbon dioxide storage in the German North Sea: Static‐to‐dynamic capacity refinement for a 10 Mt/y injection scenario

Deep Underground Science and Engineering, EarlyView.
This study assesses whether a saline aquifer in the German North Sea can sustain industrial‐scale CO2 injection at 10 Mt/year over 30 years. A 3D reservoir model is used to compare static capacity with dynamically achievable storage. The work links site‐scale injection strategy design with basin‐scale pressure response, providing a framework for ...

Sterols in Recent Marine Sediments

Science, 1970
Sterolic fractions have been isolated from Recent marine sediments representing two different environments. The fractions were characterized by infrared spectroscopy and thin-layer chromatography. The major sterols in the fractions were identified by gas chromatography and mass spectrometry.

Methanogenesis in Marine Sediments

Annals of the New York Academy of Sciences, 2008
The anaerobic conversion of complex organic matter to CH4 is an essential link in the global carbon cycle. In freshwater anaerobic environments, the organic matter is decomposed to CH4 and CO2 by a microbial food chain that terminates with methanogens that produce methane primarily by reduction of the methyl group of acetate and also reduction of CO2 ...

Sediment impacts on marine sponges

Marine Pollution Bulletin, 2015
Changes in sediment input to marine systems can influence benthic environments in many ways. Sponges are important components of benthic ecosystems world-wide and as sessile suspension feeders are likely to be impacted by changes in sediment levels. Despite this, little is known about how sponges respond to changes in settled and suspended sediment ...

Azaarenes in Recent Marine Sediments

Science, 1977
Chemical fractionation and mass spectral probe distillation reveal the presence in recent marine sediments of a complex assemblage of nitrogen-containing aromatic compounds. These azaarenes range from three- to eight-membered rings, with homologs containing up to eight alkyl carbons. In their composition, and presumably in their origin in natural fires,

Mercury in dated Greenland marine sediments

The Science of The Total Environment, 2000
Twenty marine sediment cores from Greenland were analyzed for mercury, and dated by the lead-210 method. In general the cores exhibit a mercury profile with higher mercury concentrations in the upper centimetres of the core. The cores were studied by linear regression of in Hg vs. age of the sediment for the youngest 100 years.

Sulfate Reduction in Marine Sediments

2000
The present chapter deals with the biogeochemical transformations of sulfur within marine sediments during early diagenesis. The term ‘early diagenesis’ refers to the whole range of postdepositional processes that take place in aquatic sediments coupled either directly or indirectly to the degradation of organic matter.

Osmium in marine sediments

Geochimica et Cosmochimica Acta, 1991
Osmium is enriched in ferromanganese minerals, and its concentrations follow those of other Pt-group metals except Pd. Oxidative capture during solid formation is the probable mechanism for uptake. In some sediments forming under reducing conditions (phosphorites and anoxic coastal deposits) there is also an enrichment.

The Nature of Marine Sediments

2007
The discussion in this chapter will be restricted to surficial sediments (upper few meters) found on the continental shelf (beach to the continental shelf-slope break, approximately to 100–130 m water depth) and in other nearshore environments (lagoons, estuaries, and bays).
