Algae Dataset
Every data hub, dataset, sensor, variable, paper and limitation in one tree — and for each: where it comes from, how far back it goes, how often it captures, why it belongs in a cholera study, and why it does not work everywhere.

Why it is used for cholera. Standard open-ocean chlorophyll. KNOWN TO OVERESTIMATE in turbid case-2 water, so it is valid offshore of Chakaria but not inside the estuary.
