Coral Reefs
Coral reefs on TerraPulse are organized into the coral_reef_station Locationdex —
one slot per survey site, each a place where a reef was actually visited and its condition
measured, drawn from EPA coral reef surveys. No estimates, no forecasts.

The dexes
The sites live in a single Locationdex, one slot per surveyed reef station:
| Dex | Holds | Stations |
|---|---|---|
coral_reef_station | EPA coral reef survey sites | 77 |
That is 77 reef survey sites across two Caribbean surveys — a real, sited record of where reef condition was assessed.
Provenance
Every site traces to the U.S. EPA coral reef surveys — the Puerto Rico 2011 survey and the U.S. Virgin Islands 2009 survey. Both sources are registered against the dex, so any record on TerraPulse carries a direct line back to the originating EPA survey visit.
What's in a record
Each site slot carries:
- Site — survey station identifier
- Location — latitude and longitude on the reef
- Survey — the Puerto Rico 2011 or U.S. Virgin Islands 2009 assessment
- Condition metrics — the reef and water-quality parameters recorded at the site
- Depth — where recorded
