The biological pump transports organic matter, created by phytoplankton productivity in the
well-lit surface ocean, to the ocean's dark interior, where it is consumed by animals and …

Direct observations indicate that the global ocean oxygen inventory is decreasing. Climate
models consistently confirm this decline and predict continuing and accelerating ocean …

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 …

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

Understanding the nature of organic matter flux in the ocean remains a major goal of
oceanography because it impacts some of the most important processes in the ocean …

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 …

Marine dissolved organic carbon (DOC) exhibits a spectrum of reactivity, from very fast
turnover of the most bioavailable forms in the surface ocean to long-lived materials …

The vertical separation of organic matter formation from respiration can lead to net carbon
sequestration within the ocean's interior, making the biological pump an important …

Cyanobacteria of the genus Oscillatoria (Trichodesmium) account for annual inputs of
nitrogen to the world's oceans of about 4.8× 1012 grams while benthic environments …

Particulate organic carbon (POC) is vertically transported to the oceanic interior by
aggregates and their ballasts, mainly CaCO3 and biogenic opal, with a smaller role for …
