There are four volunteers monitoring nutrients and chlorophyll a within four estuarine waters in Escambia County. You can read the 2019 update at https://blogs.ifas.ufl.edu/escambiaco/2019/08/22/nutrient-pollution-in-pensacola-bay-the-2019-lakewatch-report-for-escambia-county-waters/.
TWO LIONFISH WERE FOUND AT FT. PICKENS LAST WEEKEND
If you are diver, and dive Ft. Pickens, please let us know if you see any lionfish during your dive.
THE SEP 12th SCIENCE HOUR WILL BE MOVED TO SEP 19th
The topic for Sep is GMOs in our food systems.
