Context 1

... studied area is located in the northern part of the head of Osaka Bay, which includes the Port of Amagasaki-Nishinomiya-Ashiya (ANA Port; for short) and the eastern part of the Port of Kobe as shown in Fig. 1. The length of the area from east to west is 6.7 km with the width of 4.6 km from north to south. The survey area is largely surrounded by reclaimed land used for industrial factories and residential buildings which have been constructed since 1945. The residential areas are used as "bedroom towns" for the two mega-cities of Osaka and ...

... are limited to the weekly measurements. The vertical profiles of salinity, temperature, chlorophyll-a and DO were measured with an Alec Electronics Memory STD (a Salinity Temperature Depth Recorder with a chlorophyll-a sensor) and Hydrolab Quanta (a DO monitor) from June 3 to November 26. Measurements were conducted at 15 stations as shown in Fig. 1, in which the letter "A" of "Stations A1-A6" means along the coastline, B and C cover the middle of the survey area, and D is outside of the ANA Port. Anoxic water is defined as the concentration of DO less than 3mg/l in accordance with the current ...

... 3 shows the time change for vertical profiles of DO, temperature, salinity and density (σ t ) measured at the representative stations of D1, C3 and A4. As shown in Fig.1, Station D1 is located outside of the ANA Port, that is to say, in the head of Osaka Bay, in which the complicated hydrodynamics of the whole of Osaka Bay affect the flow characteristics. ...

... changes of temperature and salinity at Stations B2 and C3 inside of the ANA Port, bore a close resemblance to Station D1, but the behavior of the anoxic water was different from at Fig.3 Time change of vertical profiles of DO, temperature, salinity and density measured at Stations, D1, A4 and C3 Station D1, and at Station A4. In order to clarify this contradiction, it is important to check out the difference in flow outside and inside of the ANA Port. Figure 4 shows the time change in the cross-sectional distribution of DO along the observation line from sea (Station D1) to land (Station A3), denoted as a broken line in Fig.1. Black bars in the figures indicate the Nishinomiya Breakwater and the charcoal gray color indicate anoxic water. ...
