What are estuaries and what is the significance of them?

 An estuary is a place where salty water from the ocean mixes with fresh water from the land and creates a unique and special place for marine species to live, feed, and reproduce. Peconic Estuary, Long Island South Shore Estuary Reserve, New York/New Jersey Harbor and Hudson River Estuary are the four estuaries in New York State.
