Last night I was looking at the Pilot Chart Atlas for the North Pacific. (If you don't have this, it's great fun. It lists the winds and waves, etc. for each 5x5 square of ocean on a monthly basis.) I was looking at the area between the Philippines, Papua New Guinea, and Borneo. This is the lower left hand corner of the N. Pacific charts. Since the area of Indonesia just below is cut off I decided to check the Indian Ocean charts. The same area appears on the upper right corner of the Indian Ocean charts. When comparing the same area for the same month I noticed something strange. The oceans currents are different! In the case of February, for example, one charts show a South to North current just west of Halmahera. The other shows a North to South current! The edition numbers are only one year apart, '94 and '95 , so it is hard to believe that all new data was applied but maybe so. What do you think? The wind roses are identical. Steve Tripp
