Distribution of Uranium in the Indian and the Soutbern Ocean Waters
The content of uranium was determined for sea water samples collected on board M. S. SOYA on her cruises from Japan to Antarctica during the fifth and sixth Japanese Antarctic Research Expeditions (1960-61,1961-62) and in the Drake Passage on board S. S. CAPITAN CANEPA of the Argentine Navy Hydrogra...
