Calibration of unsaturation patterns in long-chain ketone compositions for palaeotemperature assessment
A series of long-chain (C37, C38, C39), primarily di- and tri-unsaturated methyl and ethyl ketones, first identified in sediments from Walvis Ridge off West Africa and from the Black Sea1, has beenExpand

A new, mechanistic model for organic carbon fluxes in the ocean based on the quantitative association of POC with ballast minerals
Abstract In simulation studies of the ocean's role in the global carbon cycle, predicting the depth-distribution for remineralization of particulate organic carbon (POC) is of particular importance.Expand

Effect of Phytoplankton Cell Geometry on Carbon Isotopic Fractionation
The carbon isotopic compositions of the marine diatom Porosira glacialis and the marine cyanobacterium Synechococcus sp. were measured over a series of growth rates (μ) in a continuous culture systemExpand

Molecular indicators of diagenetic status in marine organic matter
The fluxes of individual carbohydrates, amino acids, lipids and pigments have been determined in net-plankton, particulate matter and sediments from three sites (9°N, 5°N, and 0°N) in the centralExpand

Consistent fractionation of 13C in nature and in the laboratory: growth-rate effects in some haptophyte algae.
The carbon isotopic fractionation accompanying formation of biomass by alkenone-producing algae in natural marine environments varies systematically with the concentration of dissolved phosphate.Expand

Poly cyclic aromatic hydrocarbons in Recent lake sediments—II. Compounds derived from biogenic precursors during early diagenesis
Abstract Five groups of polycyclic aromatic hydrocarbons (PAH) thought to be derived by early-diagenetic transformations of biogenic precursors are apparently present in Recent sediments of fourExpand

Evidence for non-selective preservation of organic matter in sinking marine particles
The sinking of particulate organic matter from ocean surface waters transports carbon to the ocean interior, where almost all is then recycled. The unrecycled fraction of this organic matter canExpand

Comparison of Vertical Distributions of Prokaryotic Assemblages in the Anoxic Cariaco Basin and Black Sea by Use of Fluorescence In Situ Hybridization
ABSTRACT Individual prokaryotic cells from two major anoxic basins, the Cariaco Basin and the Black Sea, were enumerated throughout their water columns using fluorescence in situ hybridization (FISH)Expand

Compositions and transport of lipid biomarkers through the water column and surficial sediments of the equatorial Pacific Ocean
A systematic investigation of fluxes and compositions of lipids through the water column and into sediments was conducted along the U.S. JGOFS EgPac transect from l2°N to l5°S at 140°W. Fluxes ofExpand
