Everglades National Park in South Florida is the largest subtropical wetland ecosystem in North America, consisting of about 1.5 million acres of mangrove forests and other coastal wetlands. Mangroves are salt-tolerant trees that thrive amidst the harsh growing conditions of the coast.

In the Mississippi River Birdfoot Delta, there is intense vegetation loss in marshes farthest away from the river, as indicated by high values of UVVR (shown in pink).

Within the busy boroughs of Brooklyn and Queens, New York City, is Jamaica Bay—a complex urban ecosystem almost the size of Manhattan that consists of salt marsh islands, various waterways, meadowlands and two freshwater ponds.

The Prime Hook National Wildlife Refuge in Delaware is the site of a \$40 million tidal marsh restoration project—one of the largest restoration projects ever in the eastern U.S. With this project, the U.S.

Four close-up images of a longer sediment core (bottom). The light coloring indicates coarser sand that likely occurred from overwash flooding during a previous hurricane. This is one of a few cores collected in northwest Florida by the USGS and partners to help understand past hurricane activity in the Gulf of Mexico and northern Atlantic Ocean.

Two samples of beach sediment from Ichinomiya, Japan. This beach was the likely source for the sand used in the balloon bombs.

Julia Gardner was also immortalized with the naming of Ecphora gardnerae, a snail shell named in her honor.  In 1994 the state of Maryland designated it the official state fossil shell.
