isotopes were available in greater amounts at Bogallua - carried westward from the target area by currents and wind in the
lagoon.
This is partially substantiated by the presence of
turbid water west and southwest of the target area.
It must
be noted also that much of the activity at Engebi was pre-shot
and probably made up of considerable inert material, bliologi-
cally speaking.

A large number of dead and dying fish were geen in and close
to the turbid water Flowing from the target area westward inside
the lagoon between Elugelab and Bogallue eight days after the
blast.
There were some injured fish at Engebi also and two or
three badly injured goatfish were collected near the shore
(Fig. 7).
