What is this Page for?

Here at saltwedge.org are concepts, perspectives, and activities to enrich the educational experience of the science of New York Harbor, particularly as seen while sailing on schooner Pioneer, or if you can't come along in person, virtual participation over the Web. The basic science can easily be studied, learned, and enjoyed (Science can be FUN!) by doing simple, safe, inexpensive experiments and hands-on activities, using easily obtained materials like water, salt, food coloring, plastic cups, pipe cleaners and thermometers.

What is an Estuary?
What is a Salt Wedge?

To the left is a "map" (what sailors would call a "chart") of New York City and the surrounding area. What does the blue represent? Note that there are different shades of blue. What does that indicate? It shows salinity, or how salty the water is. This map illustrates the most important single defining feature of an estuary—fresh water meets salt water, with mixing, and layering—all sorts of complicated interaction, like the Salt Wedge that gives this site its name.
