The exchange of carbon on earth is one of the fundamental processes that sustains life and regulates climate. Since the onset of the Industrial Revolution, the burning of fossil fuels and anthropogenic land conversion have altered the carbon cycle, increasing carbon dioxide in the atmosphere to levels that are unprecedented...
A graphical method, based on a set of acid-base titrations, is
presented for the determination of the carbon dioxide speciation in
natural solutions. The application of this method, in conjunction
with measurements of the partial pressure of carbon dioxide with
which our solutions were in equilibrium permitted the calculation
of...
The ratio of the absolute infrared intensity, A₃/A₂, for the
parallel mode (2336 cm⁻¹) and the perpendicular mode (658 cm⁻¹)
of a nonpolar solute molecule, carbon dioxide, has been determined
in a nonpolar solvent, Nujol. The solution ratio (5.0) which has
been extrapolated to zero concentration is less than the...
A cascade crosscurrent column, packed with Pall rings, was
employed for carbon dioxide absorption from a carbon dioxide-rich
air phase by contacting with water. Absorption efficiency was
presented as the percentage of CO₂ removed versus gas flow rates for
constant liquid to gas ratios (L/G).
Curves were developed for an...
The carbon is photoelectron spectrum of CO₂ has been measured with very high photon energy resolution. The natural lifetime of the carbon is hole state has been determined from a series of spectra taken at photon energies of 308, 320, and 330 eV. The measured values of the lifetimes show...
Larvae of the Pacific Oyster, Crassostrea gigas, at Whiskey Creek Shellfish Hatchery (WCH) in Netarts Bay, Oregon, are negatively impacted by high-CO₂ water and exposure during the initial shell formation period appears to be particularly damaging. To investigate the mechanism of this early susceptibility, several cohorts of larvae at WCH...
