Description We create underwater visibility maps of Puget Sound and publish this as part of Eyes Over Puget Sound using light transmissometer data collected during routine monitoring of our marine waters.

The light transmissometer is an electronic instrument that measures how far light travels under water. Light does not travel as well in murky water. Bad visibility takes away enjoyment from a dive, although it may also keep prey from being eaten. The method of conversion from light transmission to horizontal visibility is also presented.

Underwater visibility in Puget Sound has increased during the past ten years, but there is a strong seasonal pattern to it at most locations.

This poster was presented at the 2016 South Sound Science Symposium during September 2016 in Shelton, WA.
