Marine zooplankton comprise a phylogenetically and functionally diverse assemblage of
protistan and metazoan consumers that occupy multiple trophic levels in pelagic food webs …

We have developed a global biogeographic classification of the mesopelagic zone to reflect
the regional scales over which the ocean interior varies in terms of biodiversity and function …

Oxygen loss in the ocean, termed deoxygenation, is a major consequence of climate change
and is exacerbated by other aspects of global change. An average global loss of 2% or more …

Biological oceanic processes, principally the surface production, sinking and interior
remineralization of organic particles, keep atmospheric CO2 lower than if the ocean was …

Oxygen minimum zones (OMZs) have substantial effects on the global ecology and
biogeochemical processes of marine microbes. However, the diversity and activity of OMZ …

In the ocean's major oxygen minimum zones (OMZs), oxygen is effectively absent from sea
water and life is dominated by microorganisms that use chemicals other than oxygen for …

Oxygen minimum zones (OMZs), large midwater regions of very low oxygen, are expected to
expand as a result of climate change. While oxygen is known to be important in structuring …

The efficiency of the ocean's biological carbon pump (BCP eff–here the product of particle
export and transfer efficiencies) plays a key role in the air–sea partitioning of CO 2. Despite …

The oceans' biological pump (BP) exports large amounts of particulate organic carbon
(POC) to the mesopelagic zone (base of the euphotic zone–1000 m depth). The efficiency at …

Carbon preservation in marine sediments, supplemented by that in large lakes, is the
primary mechanism that moves carbon from the active surficial carbon cycle to the slower …
