A cool set of underwater photographs of rivers from National Geographic. One of our study sites (Blue Hole Spring in the Ichetucknee River, FL) is included.
I will note that Blue Hole has fairly high nitrate concentrations, despite it's otherwise excellent condition. Which is an example of why we think that nitrate contamination may not be the whole story in Florida Springs.
