Welcome to ScubaViz.us!

***** This website is undergoing some updates. Content is still here but the site will look like crap for a bit. Sorry *****

This website is here to exploit and promote science and technologies for divers. Mainly by using existing technologies, such as satellite data, that have been underutilized. This site also highlights a number of emerging technologies that divers will find interesting. If you have any ideas for the site or would like to advertise on one of the pages feel free to email us at This email address is being protected from spambots.

These images show the measured "Kd" value (diffuse attenuation coefficient). Studies have shown that this is a good analog to represent light attenuation and water clarity. This is a calculated value based on the amount of 490nm blue light as seen from space. These are 3 different satellites that pass over daily. The relevant data range is based on what has been determined to be relevant based on in situ diver reports.
