Abstract : The distributions of Secchi depths (i.e. water transparency) with simultaneously measured standard oceanographic parameters on file at the National Oceanographic Data Center are surveyed on a global basis. An inventory of many of the oceanographic parameters is given for all Marsden squares. Correlation coefficients between Secchi depths and eleven other parameters are also tabulated. Linear regression equations for some twenty-one selected ocean areas relating Secchi depth and the other parameters are presented, and in some cases plotted. No simple and consistent relations between Secchi depth and other parameters are evident; however, several trends are noted. Forel color and oxygen measurements show trends toward an inverse proportionality with Secchi depths while bottom depth data indicate a possible direct proportionality. (Author)
