Glycerol dialkyl glycerol tetraether (GDGT) lipids are membrane lipids which were long
thought to be synthesized mainly by archaea, organisms thought to be limited to extreme …

The differing patterns of molecular abundances in organisms are fundamental to the
understanding of the biomolecular palaeontological record. All organisms contain DNA …

Throughout Earth history, almost all preserved organic matter has been incorporated in
marine sediments deposited under oxygenated waters along continental margins. Given …

A sequential extraction method (SEDEX) has been developed to separately quantify five
sedimentary P reservoirs: loosely sorbed P; ferric iron‐bound P; authigenic carbonate …

Abstract Mid-water oxygen minima (0.5 mll 1 dissolved O2) intercept the continental margins
along much of the eastern Pacific Ocean, off west Africa and in the Arabian Sea and Bay of …

For more than a decade I have taught a graduate-level course in marine sediment
geochemistry that covers many of the topics discussed in this book. The goal now is to …

Use of sedimentary organic carbon concentrations as a record of paleoceanographic
conditions is complicated by an insufficient understanding of the mechanisms controlling …

The enigma of aerobic vs. anaerobic decomposition in marine sediments was addressed by
means of a thin‐layer incubation technique. Two different 14C‐labeled plant materials, aged …

This paper addresses three related questions:(1) What factors control the efficiency of
carbon burial in sediments?(2) Are rates of anaerobic organic matter degradation …

The dynamics of the particulate organic carbon (POC) pool in the ocean are central to the
marine carbon cycle. POC is the link between surface primary production, the deep ocean …
