qu TERN I would like to poat some conflicting data. source of it, I mean the ultimate source. I don't know the Odum, from the University of Florida, in 1951 published in "Selence” some work that he had done for a Doctor's thesia, 1 believe, in which he gave data like this. Water into the coeans from the rivers had about — well depending on the dissolved atrontium -- 2.2 parts per thousand — atoms per thousand —— in silt 3.4 and voleanic organs 2.7. Jedi- mentation from the ocean had a value ranging from 1.9 to 3.4, depending upon whether it was sandstone, shale, limestone, red clay, atss, blue mid, otc. SOLOHON Is tiis part to the thousand, or 1s it atoms per thousand calcium atoms? It is a ratio of atrontium to caloium in atoms per one thousand, which I believe is cousistent with the other, and he quotes the analyses of some 50 fossils of ocean life from the early paleosoic to recent times, as giving values ranging from 1.4 te 10.5, although only three of these had values greater than 4. It was his thesis that the ratio of strontiua to calcium in geological cycles is approximately constant, and that the ratio had not shanged greatly over recent geologic ages. I would like to say that Odum did his work with flawe spectrometer, and we did a fairly comprehensive survey just as carbonate rock and fossils using a spectrograph and checked those very closely using independent standards and methods. There are no soil analyses as Krieger says. IJ talked to Robinson about a year or so ago, and those old analyses that he made in 1914 hn SOE ARCHIVES
