متن کاملAssessing possible consequences of ocean liming on ocean pH, atmospheric CO2 concentration and associated costs
More than 380 Pg of carbon have been released by human activities from fossil fuel combustion and cement manufacturing since the beginning of the Industrial Revolution. This carbon release has caused atmospheric CO2 levels to increase by ∼100 ppmv compared to the highest interglacial value of the last ∼800,000 years. Net uptake of carbon by the oceans has caused the surface ocean pH to drop by ...
متن کاملBiogeochemical consequences of macrofauna burrow ventilation†
The burrow walls created by macrofauna in aquatic sediments are sites of intense chemical mass transfer. Quantitative measurement of their significance is, however, difficult because chemistry in the immediate vicinity of burrow walls is temporally dynamic due to periodic ventilation of burrows by macrofauna. A temporally dynamic, 2D multicomponent diffusion-reaction model was utilized to depic...
متن کاملBiogeochemical variability in the upper ocean
Differences in the response times of different biogeochemical tracers to upper ocean forcing processes can lead to substantial differences in their patterns of variability. An idealized tracer with a steep vertical concentration gradient is modeled in a flow field representative of an upper ocean front. The surface distribution of the tracer is studied as a function of its response or restorati...
متن کاملProterozoic ocean redox and biogeochemical stasis.
The partial pressure of oxygen in Earth's atmosphere has increased dramatically through time, and this increase is thought to have occurred in two rapid steps at both ends of the Proterozoic Eon (∼2.5-0.543 Ga). However, the trajectory and mechanisms of Earth's oxygenation are still poorly constrained, and little is known regarding attendant changes in ocean ventilation and seafloor redox. We h...
