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

The abyssal seafloor covers more than 50% of the Earth and is postulated to be both a
reservoir of biodiversity and a source of important ecosystem services. We show that …

Ecosystems in remote regions tend to be highly specific, having historically evolved over
long timescales in relatively constant environmental conditions, with little human influence …

A chapter on the pore water of sediments and the processes of early diagenesis, reflected by
the concentration profiles therein, can certainly be structured in different ways. One …

Bottom-water oxygen supply is a key factor governing the biogeochemistry and community
composition of marine sediments. Whether it also determines carbon burial rates remains …

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 …

Pioneering deep-sea surveys established that the fauna of the continental margins is zoned
in the sense that individual species and assemblages occupy restricted depth bands. It has …

For years scientists viewed the deep sea as calm, quiet, and undisturbed, with marine
species existing in an ecologically stable and uniform environment. Recent discoveries have …

More than 50% of the Earth's surface is sea floor below 3,000 m of water. Most of this major
reservoir in the global carbon cycle and final repository for anthropogenic wastes is …

All marine species studied thus far show rhythmic temporal patterns in their behavioural,
physiological, and molecular functions, which are collectively known as biological rhythms …
