Coastal Secchi Depth Atlas
Abstract
A seasonal Secchi depth atlas has been developed for the world's coastlines. Optical data have been compiled from data gathered by the National Oceanographic Data Center and from open literature for water depths less than 500 meters. These data have been averaged by one-degree squares, sorted by season, and placed in a category of six classes of Secchi depth ranges. Four charts were used to cover the world at a scale of 1:12,233,000, and four seasons were selected to encompass 3-month intervals. Additionally, annual mean Secchi depths have been compiled in four charts. Secchi depth data were found for approximately 50% of the world's coastlines. In the areas where no optical data were available other oceanographic, meteorologic, and geomorphic data sources were used to estimate the expected Secchi depth ranges.
