Imagine hundreds of tiny (typically overlooked) reef “islands” along our coastlines. Each is a biodiversity hotspot and early warning signal for climate stress, but we rarely survey them because traditional reef-survey kits are big, expensive, and require intensive labor. Our challenge is to create a plug-and-play micro-habitat monitor that can be deployed by any coastal community in one dive and read from your phone. Over one busy weekend we’ll: 1. Stream (live or simulated) sensor data (water temperature, salinity, pH, nitrate, dissolved oxygen) through a low-power ESP32 stack. 2. Merge it with open satellite & national reef datasets so our local probe has “global visibility.” 3. Train a lightweight AI model that flags bleaching risk or pollution events hours to days earlier than human surveys. 4. Make sense of everything in a slick web dashboard: traffic-light health scores, live graphs, and one-click SMS/email alerts for rangers and fishers. |
