Is the drop in SST off Japans coast

in 1945 a sea war related matter?

In 1945 the naval war between Japan and the Allies naval force lasted another 9 months. The naval activities in the east of the Japanese Mainland were high, and the sea current system easily effected. Therefore it does not come so much as a surprise that from 1944 to 1946 the sea surface temperatures showed particularly low figures eastward of Tokyo (see graphic) .

 

EXTRACT from Ch. 4_11): The material loss in the battle was gigantic. Japan lost more than 500 warships (including 150 submarines) with a total tonnage of about 2,000,000, the figure in merchant tonnage was about 8,000,000 of which 5 Mio  (1,150 ships) were sunk by US-submarines and 1.5 Mio by airplanes. A special chapter could possibly be written on the sinking of tanker tonnage resulting in oil spills. During the war years Japan had some 700,000 tonnage permanently afloat and lost 1,500,000-tanker tonnage over the war period. The US lost 52 submarines. Many of them fell pray to depth charges. Kemp explains: The standard Japanese depth charge contained about 230lb of explosives. Anti-submarine bombs carried by aircraft were 131lb and 550lb each, the latter being preferred when available. The Japanese had no means of determining the depth of a submarine to be targeted and so the pattern of attack usually was the dropping of depth charges with a variety of settings on the time fuse. The Japanese lost 150 submarines, many of them to depth charges. It is necessary to consult special literature available in great number and detail even to imagine what happened in the Pacific war theatre. One cannot help getting the impression that WWII left its imprint on the Pacific.
