Abstract
THE transparency of sea-water has hitherto been studied, either by means of the Secchi disc or, more recently, by measuring the intensity of submarine daylight at different depths by means of photoelectric cells. Both methods are limited to comparatively small depths, where the residual daylight has a measurable intensity. In addition, the results, if no colour filters are used, are affected by the changes in spectral composition which daylight undergoes with increasing depth.
