USGS scientists are working to model shorebird habitat availability both today and in the future, given processes like sea-level rise, in an effort to support the efficient management of beaches for both people and nesting shorebirds.

Ice Jam Remnants
On April 29, hydrologic technicians Anthony Underwood and Jeremiah Pomerleau visited the USGS gaging station on the St. John River at Ninemile Bridge and found a sea of broken up, dirty ice left behind by a recent ice jam.
According to Anthony, photos don't do the size and scale of the ice chunks any justice.

Mangroves form a protective berm on a Florida Bay island
The transition between a mud flat on the interior of Bob Allen Key (Florida Bay, Everglades National Park) and the mangroves that form the islands’ protective outer berm. These black mangroves have pneumatophores – parts of the root that function like snorkels, allowing the roots to “breathe” when water overlies the mud flat. Photo: Anna Wachnicka, FIU
