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 …

Changes in oceanic primary production, linked to changes in the network of global
biogeochemical cycles, have profoundly influenced the geochemistry of Earth for over 3 …

Group I (WGI) of the IPCC produced its second report Climate Change 1995: The Science of …

An Introduction to Organic Geochemistry explores the fate of organic matter of all types,
biogenic and man-made, in the Earth System. investigates the variety of pathways and …

Global climate and the atmospheric partial pressure of carbon dioxide () are correlated over
recent glacial cycles, with lower during ice ages, but the causes of the changes are …

The cycling of carbon on Earth exerts a fundamental influence upon the greenhouse gas
content of the atmosphere, and hence global climate over millennia. Until recently, ice …

The concentration of CO2 in the atmosphere has risen from close to 280 parts per million
(ppm) in 1800, at first slowly and then progressively faster to a value of 367 ppm in 1999 …

John H. Martin, who discovered widespread iron limitation of ocean productivity, proposed
that dust-borne iron fertilization of Southern Ocean phytoplankton caused the ice age …

Twenty years ago, measurements on ice cores showed that the concentration of carbon
dioxide in the atmosphere was lower during ice ages than it is today. As yet, there is no …
