Natural logarithms of replacement rates, ck, plotted against mean salinity in tidal excursion segments. Production coefficients calculated from bottle experi- ments of June and July 1951. Natural logarithms of production rates, c", plotted against salinity in the bottles. also reflect the effects of vertical exchanges between the mixed layer and the deeper layer, which may or may not be significant. The replacement rate thus gives an estimate of the rate at which the population would increase or decrease if purely horizontal tidal exchanges were eliminated. An independent estimate of the value of ck may be obtained by actually isolating a sample of water with its natural population from tidal exchanges and noting the rate at which its population actually changes when maintained under otherwise nat- ural conditions. These two estimates should agree unless vertical exchanges are Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Marine Biological Laboratory (Woods Hole, Mass. ); Marine Biological Laboratory (Woods Hole, Mass. ).
