Measurements of ship shadow were made from a manned submersible, equipped with a downwelling PAR irradiance sensor. These measurements were made as transects under the surface ship during clear sky conditions and three separate profiles (on the shady side, under the ship and on the sunny side) during overcast conditions. Results from the clear sky measurements agree with previous numerical simulations, indicating only small errors due to ship shadow. During overcast conditions, the profiles indicate the shadow effects are detectable to considerable depth, but not at a distance of one optical depth from the ship rail on the sunny side. These measurements also demonstrate the effectiveness of manned submersibles for optical oceanographic studies.
