The videos on thermal motion of the cluster of water in state of melting ice of carbonated water and video on the layered movement of the cluster will be shown in this presentation. Although carbon dioxide in water exists in the form of molecule, it is highly soluble. The entropy of the carbonated water is decreased than the pure water. The mechanism is similar to a hydrate. But the solubility becomes zero at the temperature higher than 60°C. The lost of solubility caused by lost of the hexagonal lattice structure. The bubble together with newly joined molecule will rise up to the surface of the water. At the surface of the water, trial and error of combination of adjacent molecules is carried out by thermal motion, and it is possible to make chemical reaction by obtaining the energy from outer world. Repeating generation of the organization in renewing circumstance will result evolution.

As a tool for tracing organic carbon derived from marine macrophytes, a method for quantifying DNA biomarkers of temperate seagrasses (Zostera spp.) in coastal sediments by the real-time PCR has been developed. Using this method, seagrass DNA was successfully detected from some seagrass bed sediment cores, and the results obtained were generally consistent with organic carbon and carbon stable isotope distributions through the cores. The seagrass DNA has been detected even from deep sediment samples dated >2,000 yr b.p. by the conventional C-14 method. Spatial distribution of seagrass DNA biomarkers over offshore surface sediments indicated that there are specific sink" regions of seagrass-derived organic carbon nearby source areas. A quantitative relationship between the amount of seagrass DNA and the concentration of seagrass-derived organic carbon in the sediment is being explored now."

Mn oxides, among the strongest common chemical oxidants except oxygen, play an important role in the environmental cycles. For measurement of Mn(II) oxidation and sorption reaction on the surface of six manganese oxide minerals (cryptomelane, todorokite, vernadite, hausmannite, Na-birnessite, Na-buserite), the rates of Mn(II) removal from aerated solutions (0.01 mM of initial [Mn]; 50mM of NaCl; 2mM of Hepes buffer) in 1-L brown bottles were monitored over a pH range from 7.6 to 8.2 for five days after manganese oxide addition (2.0 mg) at room temperature. The Mn(II) oxidation rate on the surface of these minerals was proportional to [OH^-] to the power of 0.38-0.59 in the pH range.
