Show HN: Submarius – Global water clarity for divers

[celloer]

Submarius started as just a dashboard for diving conditions, but I quickly realized that there is simply no API for water clarity, nor even a simple way to calculate it. Divers call it viz, and it is one of the most consequential factors for a diving experience. So I dove the viz rabbit-hole. I landed on a state-augmented ensemble kalman filter. More details on the /clarity page. My question for the HN audience is if anyone knows of a better way of doing this? There is a ton of satellite data to train on, but a lot of it is messy (clouds read as turbid water, shallow reefs reflect abnormally causing bad readings, etc). Appreciate any feedback on the subject. Enjoy the read!

"Not another dashboard for every activity on the water" means has about 8 identified activities and tunes the dashboard, in fact IS another dashboard for every activity.

(not mine: has sailing, not rowing)
