Pagination or Media Count:
This report, which discusses an investigation into the volume attenuation coefficient of light in the sea, also describes a newly developed null-balance transmissometer capable of measuring this coefficient of light to a depth of 2,000 meters. Data obtained to a depth of 700 meters are presented. These data cover that portion of the spectrum from 4980A to 5800A.
