perceived while steaming. It is not hard to deduce that this area 

 corresponds to the boundary between the Equatorial Countercurrent and 

 the southern Equa"&orial Current, Farther south at the northern end of 

 Djailolo Passage;, V-' 12"Nj, 129° 36"E, the current was Nx7/ wxzh a velocity 

 of 0„5 knots.. This area appears to be where the tip of the southern 

 Equatorial Current which flows west along northern New Guinea strikes 

 the islands of Haimahera and Morotal and turns northward o 



After we passed through Djailolo Passage on July 3 the wind shifted 

 to the south, hat its force did not decrease, remaining at 5 to 6j and 

 the seas were rather high„ Thereafter until we passed Ceram I„ the 

 wind frequently shifted to southwest or sovith, but after we passed Ceram 

 and entered the Banda Sea until we arrived at Timor the wind blew 

 steadily from the southeast vith forces of 4 to 5.. This was the so- 

 called easterly monsoon of the Banda Seaj, a seasonal wind which continues 

 until Augijisto It is said that the strength of this wind gradually 

 declines m September and Octobero 



The color of the sea water every^/vhere between Tobalai I„ and the 

 west side of Ceram was notably poor as compared with that of the waters 

 of the South Sea Islands, E-ven beyond Ceram in the Banda Sea the water 

 color appeared generally to be unfavorable, however p farther south near 

 Timor where the first station was fished off Ifetar I, the water color 

 seemed rather good. Observations made during the first fishing trial 

 showed a transparency of 4-0 meters. 



The vertical changes in water temperature at that position were 

 27,9^ at the surface, 27,4-^ at 25 meters, 27,3° at 50 meters^ 23,4^ at 

 iOO metersy 14,3° at 200 meters, 12,1° at 300 meters. 



On July 8 the vessel sailed from Dilli on Timor lo, proceeded east 

 around the north coastj rounded the eastern tip of the island, and 

 headed into the Timor Sea, At this time the wind was from the north= 

 east and the force remained unchanged at 4 to 5, The air temperature 

 at noon vias as low as 26.5^' and as a result we felt quite cold. 



While anchored at Dilli we made inquiries concerning the weather 

 there and -found that generally fey, June, July, and August are the dry 

 season while January and February are the rainy season, the two sensons 

 thus being just opposite to those of the Inner South Seas, D-jring the 

 so=called northeast monsoonj, which is the dry season^, dry cool winds 

 bloWc, and although it is in the tropics one feels cool and refreshed. 

 During the day in the Dilli region the seasonal wind begins to blow 

 around 10s 00 a,m„ and ceases around 3300 pom,, the morning and evening 

 being usually completely windlesSc During the rainy season the wind 

 blows from the northwest,, 



Observations taken at the second fishing station in the Timor Sea 

 showed a transparency of 27 meters. The sea water seemed somewhat turbid 

 compared to the previous stationj and the vertical changes in water 

 temperature were 26, 8o at the surface^ 2.6,8° at 25 meters, 26,7° at 50 

 meters, 23,.^.'^' at 100 meters, 13, 2^^' at 200 meters, and 10,2° at 300 meters.
