invasive species

My underwater encounter with Caribbean reef sharks, Nassau, Bahamas.

I looked over the edge of the boat at the slim shadows schooling below. Beneath the crystal blue water I could only make out their forms. Their shape, number, and the way they swam over and past one another reminded me of a bucket of minnows.

Welcome! This is the first of what will be many pieces on how different people relate to our shared waters.

Unsightly multi-colored algal blooms appeared earlier than usual on lakes across Wisconsin in the summer of 2012.

When we think about aquatic invasive or non-native species these days, we often think of Asian carp moving north towards the Great Lakes or zebra mussels spreading across state waterways.
