Remote-Sensing Study of the Effect of Typhoon on Chlorophyll-a Concentration in the Southeast China Sea
In this paper,through the study of MODIS-3A-data of chlorophyll-a and sea surface temperature(SST) before and after typhoon for about one month,the author finds a great effect on SST and chlorophyll-a concentration.The SST averagely falls 2~3℃,even 10℃.The chlorophyll-a concentration rises 1.43 times as much as in the Zhanjiang and Yangjiang Area,but in the East China Sea it averagely rises 2.44 times and the highest increase is 9.95 times as much as its usual status.Moreover,this increase postponed about 3~5 days.Thus it can be seen the potential capacity of using satellite data to detect the variation of marine environmental factors such as chlorophyll-a concentration and SST by typhoon.
Environment and development have become a important problem for world oil industry continuous development.Coordinated development of environment,resources and economy relates directly to the future of oil industry.In order to obtain considerable development in Chinese pipeline of natural gas in 21st century,Chinese oil enterprise must value management and quality,perform HSE and TQC management system.The paper analyses main contents and features of HSE and TQC.The cast for performing HSE and TQC show us foreign enterprise how to use HSE and TQC.Only in completely adoption of HSE and TQC,can the competitive ability of Chinese drilling and production technology be increased in international market.
