The seabed plays a key role in the marine carbon cycle as a) the terminal location of aerobic
oxidation of organic matter, b) the greatest anaerobic bioreactor, and c) the greatest …

Benthic O2 availability regulates many important biogeochemical processes and has crucial
implications for the biology and ecology of benthic communities. Further, the benthic O2 …

Microbial cells buried in subseafloor sediments comprise a substantial portion of Earth's
biosphere and control global biogeochemical cycles; however, the rate at which they use …

This paper presents a new non-invasive technique for measuring sediment O 2 uptake that,
in its concept, differs fundamentally from other methods used to date. In almost all natural …

Coastal wetlands are an important source of methane emissions, and understanding the
mechanisms that control methane emissions from coastal wetlands is of great significance to …

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

Respiration represents the major area of ignorance in our understanding of the global
carbon cycle. In spite of its obvious ecological and biogeochemical importance, most …

The oxygen dynamics in the rhizosphere of Zostera marina was studied by use of planar
optodes. Oxygen leakage to the rhizosphere was restricted to the root tip and extended only …

In situ measurements in a shallow water sediment were performed using three different
modules—a microprofiling unit, a transparent benthic chamber, and a planar optode …

Deep-sea whale falls create sulfidic habitats supporting chemoautotrophic communities, but
microbial processes underlying the formation of such habitats remain poorly evaluated …
