The low levels of Sr99 in the plankton may be due to the low amounts
present at the time of collection and to the unavailability of sr90, which
may be explained on the basis of solubility, coprecipitation with calcium
carbonate, competition with calcium,
and isotopic dilution by stable

The small fish collected after Wahoo had essentially the same radioisotopic composition as the plankton samples.
