The mixing rate of sea water for 1 liter of land waters is 1/140 liter for sample No. 1, 1/100 liter for No.2, 1/100 liter for No.3, 1/130 liter for No.4, 1/70 liter for NO.5, 1/80 liter for No.6 and 1/60 liter for No.7.

(3) For two samples (No.6 and No. 7) on the KITA KOJIMA, the composition of land water which was mixed with sea water was almost the same. Therefore, the history of No.6 and No.7 was alike. (4) Although sample No.5 on MINAMI KOJIMA was collected from a large of guano, like No.6 and No.7. the composition of land water which was mixed with sea water for making up No.5 was different from the composition of land waters for No.6 and No.7.
