Sea surface electric field observations off the coast from Goa (15°25'N, 73°47'E) to Madras (13°04'N, 80°15'E) around Sri Lanka, in a distance range 25-135 km from coast, during 9-2...Sea surface electric field observations off the coast from Goa (15°25'N, 73°47'E) to Madras (13°04'N, 80°15'E) around Sri Lanka, in a distance range 25-135 km from coast, during 9-20 May 1983 were taken. In this paper we have examined the diurnal variation of electric field in the Arabian Sea, Indian Ocean and Bay of Bengal regions covered during the cruise of the research ship ORV Gaveshani. An aspect of electric field dependence on coastal distance and Aitken Nuclei concentration has also been studied. An attempt to examine the latitude dependence of field was also made. Results obtained in the above studies are presented and compared with those obtained elsewhere.展开更多
In the tourism industry, transportation is the greatest consumer of energy and contributes the largest amount of CO2 emissions （ECCE）. Airplane flights make up between 60% and 70% of all forms of tourism transport. ...In the tourism industry, transportation is the greatest consumer of energy and contributes the largest amount of CO2 emissions （ECCE）. Airplane flights make up between 60% and 70% of all forms of tourism transport. Since airplane travel is the main way for tourists to access islands, airplane travel receives considerable attention in the study of the relationship between island tourism transportation, environment and economy. However, the pa- rameters adopted to estimate ECCE in the literature are usually either out-of-date or taken from papers not written in China. To improve the accuracy of estimates, all the parameters used in this paper are current and were obtained locally. Based on these parameters and a bottom-up approach, a more accurate estimation of ECCE for the off-shore island city of Haikou was obtained in 2012. The results indicate that 24.30% of the city＇s energy con- sumption, 33.89 P J, was due to tourism transportation, while CO2 emissions were 2.54 Mt. It is incorrect to assume that tourism is ＂an industry with no pollution＂. In Haikou, for example, tourism turns out to be the major form of en- ergy consumption in the city. This paper makes several suggestions intended to minimize the negative environ- mental impact from tourism transportation. These include recommending longer stays, a decrease in the number of flights, taxation of airplane emissions, and the setting up an environmental recovery fund.展开更多
