| 内容記述 | From the results of echo sounding along the 125°E longitude covering the areas of the Philippine Basin, Ryukyu Trench, Ryukyu Island-ridges, Okinawa Trough-like Basin, Continental Slope and Continental Shelf of the East China Sea, the following characteristic features were found. 1. The Philippine Basin from 20°-00.0’N to 21°-10.0’N sounded 5700-5900m in depth and with only very slight relief, but therefrom northwards to 22°-00.0’N, the depth becomes 700-800m thus showing a high relief of the bottom configuration. From the marginal area of the trench, to the Ryukyu Trench the bottom topography is irregular and the slope is rather gentle. 2. On the southern slope of the Ryukyu Island-ridges the depths at 2400m and 5900m reveal step-topography, above which the slope inclines at 3° and 5°-30’, respectively. 3. At 25°-00.0’N, 125°-00.0’E about 30km west-north-west of Miyako Island a rugged topography exists, and the structural topography of Miyako Positive is exhibited. 4. The Okinawa Trough-like Basin shows a rather fiat topography, and at its central parts exists a submarine ridge whose summit measures 850m in height and the shallowest part is at 25°-34.8’N, 125°-03.8’E where the depth recorded is 1199m. 5. At 85km northeast of Cape Sekibi Syo is the Sekibi Syo Northeast Spur (tentative name) extending southeast the continental shelf. At its central part is a saddle-shaped depressed area. 6. On the continental shelf at 50-70m and at 90-110m is developed a terrace topography. | |||||
