The use of biomarkers in combination with stable isotope analysis is a new approach in
microbial ecology and a number of papers on a variety of subjects have appeared. We will …

Organic matter that is deposited in aquatic sediments is subject to an intense diagenetic
reactor that determines how much organic carbon is eventually preserved in sediments. The …

Organic carbon processing at the seafloor is studied by biogeochemists to quantify burial
and respiration, by organic geochemists to elucidate compositional changes and by …

Construction and maintenance of burrows by macrofauna have large implications for the
microbiology and biogeochemistry of marine sediments. Although a wealth of new …

Background Bioturbators affect multiple biogeochemical interactions and have been
suggested as suitable candidates to mitigate organic matter loading in marine sediments …

13C tracer experiments were conducted at sites spanning the steep oxygen, organic matter,
and biological community gradients across the Arabian Sea oxygen minimum zone, in order …

Objectives The marine benthic nitrogen cycle is affected by both the presence and activity of
macrofauna and the diversity of N-cycling microbes. However, integrated research …

The goal of this field study was to provide insight into three distinct populations of
microorganisms involved in in situ metabolism of phenol. Our approach measured 13CO2 …

In order to compare and quantify sediment reworking activities by different species/functional
groups of macrofauna, a laboratory experiment was carried out with species from the …

A suite of organic biomarkers was examined in six sediment cores from two shelf-basin
transects in the Chukchi and Beaufort Seas of the Arctic Ocean to compare the sources and …
