The positlor: of the third station was soiithv/sst of Tanirabar 2o 

 in the westei-n part of the Arafura Soao The current at this position 

 flowed southwest and a lew Telocity of 0-33 knot was detected o It is 

 thought that the current which flows west in the northern part of th© 

 Arafura Sea strikes Tanimbar I ,. and. turns southwssto The transparency 

 was £7 meters and the ?@rties4l ehangea in water temperature were 26o2° 

 at th© surfac©, 26cl^ at 25 meters j, 26cO° at 50 meters j, 19o8^ at 100 

 meters, 14^9^ at 200 meters^, and 10o9° at 300 met^rgo The temperature 

 at the 100=-iaetsr level was lower than that in the Tiseor Seao fhts was 

 the ©niy groaad we fished in the .irat^wra iie&c fhere-afii-er we sioresd 

 north into the Banda flea and ran fishing stations at six places around 

 th& islands in the eastern part of that body of waters. Daring these 

 opera-clons in the Banda Sea we eonstantly encountered the southeast 

 monsoons To be more exact, the wind was from th© ESE and it blew 

 steadily with forees generally from S to 5o The air temperature 

 was around 25 cr ?6 degrees ^ and those of us who were aecustomed to 

 the h©at of the Inner South Seas ssouM feel the coolness soaking 

 into Ota* bodieso To sunrniariKa the results of the oceanographie ob=

and the water eolar appsarec^ ,0 ds arcuti:-. « ;c. 4 on the standard 

 w&ter color gauge. Considering only the Banda Sea,, it seemed that 

 the water color was generally mere fa-srorable ia the eastern than in 

 the western parte As for the vertical changes in water temperature, 

 whereas In the Inner South Seais th© difference between the surfaee 

 and the SO^meter level is only Ocl° = Oo2*' or almost negliglbles, in 

 this area it is 1° = 3** Th© temp-? rata res at th© 100=3iieter levsl 

 had & minimum of 18c3° and a maxlm-ura of SloS'^j far lower than the 

 24=25° of the waters of our South Sea islands o After eompleting 

 fishing tests at four places in th© Banda Sea wa made our last 

 station at the eastern end of Cer&n lo la this area all there is 

 to record of oeeanographic conditions is that the eurrent was north= 

 westerly with a velocity of OoS knots o In other respects the 

 situation was the same as in the Band* Soa^ with nothing worthy of 

 special note „ 



On July 21 we traversed Dampier Strait and set a coiurse for 

 Palauo I will conclude with some remarks on th® currents and 

 oceanographie conditions which were observed along the wayo 



On July 22 at the noon position of 1** 51°Mp 132° ICE th© current 

 flowed A'S;7 at the low velocity of 0o36 knot. It is thought that this 

 area may be the northern limit of th© southern Equatorial Current o 

 The water color improved notably from this area on, and while steaming 

 we (saught one small yellowfin (76 em long) on a trolling line. 



On July ^ at th© noon position of 4° IT'N^ 133° 28 "E th© 

 current flowed ESE with a velocity of lc38 knots, indi-sating that w© 

 were in the Kiuatorial Colsnter-gurreato On th© following day, the 

 24thp at ^he noon position of 6° If.'N, 154® 0°E tha current was SSE 

 with a veiooity of 0o97 knotj. froia which w© could se© th© northward
