“…Though plankton organisms are obviously a part and not all, of the suspended materials in the sea, it has been found that a fairly good correlation exists between transparency and plankton volume (MARUMO [8], Koizumr [9] Table 6. The values of F that were recorded as 1-2, etc.…”

“…The author [20], dealing with the oceanographical data of St. " X " during March 1948-February 1950, has found that the month-to-month variation of water temperature is not so smooth in late autumn or early winter as would be expected, but for the sake of adequacy of data he has refrained from deciding whether it is an ordinary occurrence in the year or not. After that time, however, evidence of the predominance of the Kuroshio water in late autumn or early winter also at stations on the "C" line (the observational line along the latitude of 38°16'N, to the east of Kinkazan) has been shown in different representation by MASUZAWA [21].…”

The author's intention is to investigate the variation of hydrographic conditions in the sea region of the Ocean Weather Station " Extra " (39°N , 153°E) from the standpoint of heat balance. The heat exchange between sea and atmosphere, also, is examined for the same region, which examination is necessary for carrying out the said intention.The main results obtained are summarized as follows : 1) The evaporation from the sea surface, the " BOWEN ratio ", the sensible heat given to the atmosphere, and the total energy loss from the sea surface have all a similar type of seasonal variation, with larger values in winter and smaller ones in summer.2) On an annual average, the amount of heat brought into the region of St. " Extra " by ocean currents is comparable to the amount of heat used for evaporation which is about twice as large as the effective radiation, and plays the most important part in the heat balance.Of course, the relations are different for the seasonal and the monthly values.3) St. "Extra", when compared with another Ocean Weather Station " Tango " (29°N, 135°E) on the Sea adjacent to Japan, is characterized, in general, by a little lower evaporation, much greater sensible heat exchange, and, in annual mean, greater total energy exchange.4) The most important conclusion as to the seasonal variation of hydrographic conditions is that the Kuroshio water is ordinarily prevalent in the region of St. " Extra " from spring to autumn, while in winter a water mass of Oyashio origin predominantly flows into this region.
