Use the radio buttons to see different scenarios. The plus sign is for zooming in, the minus sign zooms out, the arrows pan the map, or you can use the mouse. The sea level rise data is in translucent blue, and if you zoom in too far the data goes away.
The input box above the map lets you type in addresses or places and will find them for you. For this map, only New York Metro places would be relevant to find. Here are some samples you can try out:
