The ocean has been a regulator of climate change throughout the history of Earth. One key
mechanism is the mediation of the carbon reservoir by refractory dissolved organic carbon …

Diatoms sustain the marine food web and contribute to the export of carbon from the surface
ocean to depth. They account for about 40% of marine primary productivity and particulate …

Lagrangian analysis is a powerful way to analyse the output of ocean circulation models and
other ocean velocity data such as from altimetry. In the Lagrangian approach, large sets of …

Atmospheric methane removal (eg in situ methane oxidation to carbon dioxide) may be
needed to offset continued methane release and limit the global warming contribution of this …

This chapter addresses the biogeochemical cycles of carbon dioxide (CO2), methane (CH4),
and nitrous oxide (N2O). The three greenhouse gases have increased in the atmosphere …

The “biological pump” is the process by which photosynthetically-produced organic matter in
the ocean descends from the surface layer to depth by a combination of sinking particles …

Abstract The Southern Ocean houses a diverse and productive community of organisms,.
Unicellular eukaryotic diatoms are the main primary producers in this environment, where …

Baleen and sperm whales, known collectively as the great whales, include the largest
animals in the history of life on Earth. With high metabolic demands and large populations …

Abstract The Southern Ocean, although relatively understudied owing to its harsh
environment and geographical isolation, has been shown to contribute substantially to …

The signals are everywhere that our planet is experiencing significant climate change. It is
clear that we need to reduce the emissions of carbon dioxide and other greenhouse gases …
