Operation Dew refers to two
separate field trials conducted by the United States in the 1950s.
The tests were designed to
study the behavior of aerosol
Dew took place from 1951-1952 off the southeast coast of the United
States, including near Georgia, and North and South Carolina.
Operation Dew consisted of two sets of
trials, Dew I and Dew II. The tests involved the release of 250
pounds (110 kg) of fluorescent
from a minesweeper
off the coast.
Operation Dew I was described in a U.S.
report known as "Dugway Special
Report 162", dated August 1, 1952. The purpose of Operation Dew was
to study the behavior of aerosol-released biological agents
Operation Dew I consisted of five separate trials from March 26,
1952 until April 21, 1952 that were designed to test the
feasibility of maintaining a large aerosol cloud released offshore
until it drifted over land, achieving a large area coverage. The
tests released zinc cadmium
along a line approximately off the coast of Georgia,
North Carolina and South Carolina. Two of the trials dispersed
clouds of zinc cadmium sulfide over large areas of all three U.S.
states. The tests affected over 60,000 square miles (150,000 km²)
of populated coastal region in the U.S. southeast. The Dew I
releases were from a Navy minesweeper, the USS Tercel
Dew II involved the release of fluorescent particles and
spores from an
aircraft. Dew II was described in a 1953 Army report which remained
classified at the time of a 1997 report by the U.S. National Research Council
concerning the U.S. Army's zinc cadmium sulfide dispersion program
of the 1950s.
