The flux of carbon to the deep ocean can be measured directly by collecting sinking particles (living and dead microscopic organisms, faecal matter) in sediment traps, and indirectly using ...

The ocean is a vital part of our planet's climate system. Through its global circulation patterns, the ocean draws vast ...

However, through time-evolutive phase analysis of new and published high-resolution benthic foraminiferal oxygen and carbon isotope records across the global ocean, the authors find that ...

First developed in the late 1940s at the University of Chicago by Willard Libby, the technique is based on the decay of the carbon-14 isotope. Radiocarbon dating has been used for historical studies ...

Oxygen isotopes in the forams indicated that the whole ocean ... model, developed by the National Center for Atmospheric Research in Colorado, that is one of the least sensitive to carbon dioxide.

Mid-ocean ridge basalts (MORBs), located far from subduction zones, are typically thought to be unaffected by subduction ...

There is carbon isotope evidence for life ... Lerman, A. A model of Phanerozoic cycles of carbon and calcium in the global ocean: Evaluation and constraints on ocean chemistry and input fluxes.

Dozens of other companies and academic groups are pitching the same theory: that sinking rocks, nutrients, crop waste or seaweed in the ocean could lock away climate-warming carbon dioxide for ...

as part of a project to grow tiny organisms known as phytoplankton that absorb carbon dioxide from the ocean. (Gigablue via AP) ...

they produced what paleoclimatologists call a “plumeworld ocean”, for which we now have direct evidence. The plumeworld was relatively brief, as carbon dioxide levels skyrocketed and fell ...

From the grounds of a gas-fired power plant on the eastern shores of Canada, a little-known company is pumping a slurry of minerals into the ocean in the name of stopping climate change.
