| Abstract |
In order to observe hydrological characteristics in the Gulf of Yeong-il. measurements of water temperature have been carried out from February to August 1983, and from August 1985 to December 1986. Surface water temperatures are closely linked to air temperature and solar-radiation for all littoral stations. Seasonal and annual variations of all horizontal stations are very similar to one another. Vertical variations of water temperatures for the stations located along the central-line of the Gulf are characteristic (and observed) as thermoclines and thermal stratifications in the hottest summer-time (August). It is interesting to note that water column temperature of July and September are rather warmer than August. on account of a cold water mass coming from NE direction. For example, surface temperature in June 1982 was above 19't, but the water below a depth of about 30m drastically drops to 4't:. It is indicative of invasion of water mass from cold current or deep sea. |
