l\J'o. 7. 1959] (425) CHEMICAL COMPOSITION, OF THE WATERS OF SOME PONDS ON THE EAST ONGUL ISLAND, ANTARCTICA. Ken SUGA WARA * and Tetsuya TORII** Abstract Samples were collected by T. Tonn from three ponds located on the East Ongul Island not far from Syowa Base of the Japanese Antarc­tic Expedition. The results of analyses are listed in Table 1. It is evident that the waters had been supplied from the snow which had fallen on the area during the winter time. At the same time, it is also evident that the major portion of the dissolved salt was directly transported from nearby seas in the form of spray. Otherwise, the high salinity of the waters can not be ex­plained. Then the salt composition of the pond waters is expected to coincide with that of sea salt. Actually, this is not true. When the chlorine concentration is chosen as standard and ratio of individual elements to chlorine, M/Cl, is calculated, the M/CI vnlue is not always equal to the corresponding sea salt value (see Table 2). Consequently, M/CI pond water/M/CI sea water is for some elements greater than unity, pointing to relative enrich-ment of these elements in the pond waters, while it is smaller than unity for other elements which are diluted in the pond waters in relative to chlorine. The observed difference in salt composition between the pond water and sea water can be explained by SuGAWARA's idea of" Syn-bubble­bursting fractionation of sea salt ", the funda­mental of which is that when a small droplet is formed through collapse of a bubble of sea foam and is emitted into the air, the salt com­position of the spray droplet is different from that of the main sea water. Theory of the "Syn-bubble-bursting frac­tionation " has been touched on in SUGA w ARA' s paper " Strontium and calcium distribution in western Pacific, Indian and Antarctic Oceans ", Records of Oceanographic Works in Japan (Special Number 2) March, 1958, and its details are destined to be presented at the International Oceanographic Congress scheduled to be held in the coming September in New York. �:'HJJ::. h � 0) i!lvk � ;t, ::t :;,, '.7'' ;1,, IM:; _I::�= ls:if.
