 This week in class we learned about estuaries and their importance in the environment.

Estuaries are semi-enclosed areas where freshwater and saltwater meet and mix. We learned

how characteristics of estuaries such as salinity, substrate, and temperature affects the

estuaries and the organisms that function in these estuaries. Estuaries have a rich supply of fish

and many of them use the estuary as nurseries. When the young fish are grown enough they

move on to either the fresh or seawater side. We also learned about intertidal zones which are

the narrow fringe along the shoreline that lies between the highest high and lowest low tide. We

learned how organisms cope at these environments.
