Advances on The Formation Mechanism of N2O and Ammonia-oxidation Archaea in Marine

摘要

Abstract:Nitrous oxide is an important trace greenhouse gas in the atmosphere,which has a 310 times greenhouse effect than CO2 and consumes ozone in the stratosphere by photochemical reaction.Since the industrial revolution,N2O concentration in the atmosphere has increased by 20％.Ocean is usually thought to be the net source of N2O in the atmosphere,natural source accounting for one third of the total source and N2O from ocean accounted for 22％-25％ of the natural source.
