Background Light Measurement at the DUMAND Site
Abstract
Ambient light intensities at the DUMAND site, west of the island of Hawaii were measured around the one photoelectron level. Throughout the water column between 1,500m and 4,700m, a substantial amount of stimulateable bioluminescence is observed with a ship suspended detector. But non-stimulated bioluminescence level is comparable, or less than, K40 background, when measured with a bottom tethered detector typical of a DUMAND optical module.
