Quantifying the rates of biogeochemical processes in marine sediments is essential for
understanding global element cycles and climate change. Because organic matter …

The deep sea encompasses the largest ecosystems on Earth. Although poorly known, deep
seafloor ecosystems provide services that are vitally important to the entire ocean and …

Coastal hypoxia (defined here as< 1.42 ml L− 1; 62.5 μM; 2 mg L− 1, approx. 30% oxygen
saturation) develops seasonally in many estuaries, fjords, and along open coasts as a result …

The intensity, duration and frequency of coastal hypoxia (oxygen concentration< 63 μM) are
increasing due to human alteration of coastal ecosystems and changes in oceanographic …

Stable isotopes have been used extensively to study food-web functioning, that is, the flow of
energy and matter among organisms. Traditional food-web studies are based on the natural …

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

Decreasing concentrations of dissolved oxygen in the ocean are considered one of the main
threats to marine ecosystems as they jeopardize the growth of higher organisms. They also …

The Pakistan Margin is characterised by a strong mid-water oxygen minimum zone (OMZ)
that intercepts the seabed at bathyal depths (150–1300m). We investigated whether faunal …

Glaciers along the western Antarctic Peninsula are retreating at unprecedented rates,
opening up sublittoral rocky substrate for colonization by marine organisms such as …

Because of the unique conditions that exist around the Antarctic continent, Southern Ocean
(SO) ecosystems are very susceptible to the growing impact of global climate change and …
