About Chlorofishy

Chlorofishy is built by one person (me, Mathew Auric) to answer one question honestly: where did this ocean data come from, and how fresh is it? Every other satellite fishing chart I'd used answered that with a pretty, cloud-free picture and no way to check its work. This is the alternative.

Why this exists

I fish offshore, and I got tired of chasing a temperature break that turned out to be three days old by the time I found it: not because the chart was wrong, but because it never told me how old the data was in the first place. Satellite composites fill cloud gaps with modeled estimates and don't always say so. A raw satellite pass has real holes where the satellite genuinely couldn't see the water, and that's useful information too, if you can tell the difference.

Chlorofishy shows both: the composite and the individual pass, labeled as what they actually are, with the capture time, satellite, and native resolution attached to every reading. See data sources for the full breakdown of what feeds the map and how fresh each piece of it is.

What I built

The pipeline, the database, and the frontend map are all my own work, pulling public satellite and buoy data from NASA and NOAA, processing it into tiles, and rendering it with nothing hidden about where a pixel came from. It started as a personal tool for my own trips and grew into the product this site describes. See how to use Chlorofishy for what that looks like in practice, or read the articles for the ocean science and fish behavior behind it.
