Method to Evaluate the Age of Groundwater Inputs to Surface Waters by Determinin - 상세정보 | 인제대학교 ....

자료유형 : Article, Content Provider : Supplemental Index, 초록 : We previously discovered a method to estimate the groundwater mean residence time using the changes in the enantiomeric ratio of metolachlor ethanesulfonic acid (MESA), (2-[(2-ethyl-6-methylphenyl)(2-methoxy-1-methylethyl)amino]-2-oxoethanesulfonic acid), a metabolite of the herbicide metolachlor. However, many grab samples would be needed for each watershed over an extended period, and this is not practical. Thus, we examined the use of a polar organic chemical integrative ...

Deep-Sea Biology

What is hydrothermal vent? ; A hydrothermal vent is a crack or breakage in the Earth’s surface. Water which is heated by the internal heat of the Earth is released from the vent. The source of this water is cold sea water (2o C) which seeps into the fractures and is heated by the hot magma (1400oC) found in shallow chambers under the sea floor. There are two general types of hydrothermal vents. One is where water spreads out over a large area.The temperature of this water is between 10 and 20°...
