Optical Properties of Sea Water - Entrance of Tokyo Bay , Japan ( 2 ) -
초록
Optical properties of sea water were studied in the entrance of Tokyo Bay, Japan. based on the data obtained from seven oceanographic stations in June. 1985. The observation of surface irradiance and underwater irradiance of sea water for eight kind of wavelength (378, 422, 481, 513, 570, 621, 653. 677nm) of sun light was conducted using the underwater irradiameter (Isigawa # SR-8). The mean att;enuation coefficient of the sea water was appeared to be 0.245 (0.042-0.776) and the attenuation co~fficient of the sea water for wavelength appeared such as 0.227 for 378 nm, 0.186 for 422 nm. O. 175 for 481 nm. O. 176 for 513 nm. O. 185 for 570 nm, 0.337 for 621 nm. O. 321 for 653 nm, O. 348 for 677 nm. The transparency was 7.0 m (5.5-9 m). water color was 10 (8.0-13.0) in the study area and the sun altitude was 60.95
