Like Lamont VI , this list contains only results on samples of known age (most of which formed during the past ten years). The measurements were made largely in order to gain an understanding of the distribution of radiocarbon within the dynamic carbon reservoir. Again, the data are not reported primarily with the idea of drawing new conclusions but rather to bring together in one place information which is presently scattered throughout the literature or which otherwise might remain unpublished.Although the system of data presentation is essentially the same as that adopted in our previous paper, a change has been made in the normalization formula:previous relationship (Lamont VI) Fonselius and Ostlund,1959. t the relatively high C' concentration probably reflects the presence of bomb-produced C-14. values (approximating-i00 per mil), b) the Gulf Stream is a significant contributor to North Atlantic waters, and c) Atlantic circulation may be cyclic (Broecker and others, 1960).3) The most difficult problem is the evaluation of results on samples from lagoons, estuaries and other restricted parts of the ocean. In these cases the contribution of limestone-derived carbon from terrestrial drainage may cause a significant depression in the initial z. Whether this is the explanation for the low value of the Pearl Harbor sample (L-576'D, this date list) is not certain; more probably, the result implies a finite age of the sample at the time of colhttps://www.cambridge.org/core/terms. https://doi
