1985-2018 Lionfish Invasion
Lionfish invasion (1985-2018). Lionfish invaded US Atlantic coastal waters, the Caribbean Sea, and the Gulf of Mexico with unprecedented, alarming speed. Though reports of sightings date back to the 1980s, it is only recently that the species has exploded in numbers and range.

Quadpod Recovery
USGS team and R/V Savannah crew prepare to lower the quadpod deployed at the nearshore site onto the deck during recovery operations. Note all the hairy encrusting organisms that grew in 3 months and how close to the shoreline the ship is.

Fieldwork on Florida Bay Islands
A USGS researcher conducts fieldwork on Buttonwood Key, an island in Florida Bay, to determine the impacts of Hurricane Irma. The storm left thick deposits of mud on the island, which are being measured, sampled and photographed. Many of the islands in Florida Bay have open mudflats in the center, surrounded by mangroves on the perimeter.

Berm at Jim Foot Key, Florida (2018)
In Photo: The red circle indicates the same position as shown in the April 2014 photo. The mangroves have lost all their leaves and the berm is significantly thinner following the storm.

Low dunes near Cape Canaveral launch pads often overwash during storms
Low dunes near Cape Canaveral launch pads 39A and 39B often overwash during storm events, transporting sand landward. Critical infrastructure may be buried or flooded. In addition, significant landward transport of sand may lead to extensive shoreline erosion.

Estimated and measured bathymetry offshore of Madeira Beach, Florida
Estimated and measured ocean depths (bathymetry) from Madeira Beach, Florida. Each panel shows same geographic area. m = meters. Left: Snapshot transformed from original oblique camera view to overhead “map” view. Middle: Bathymetry estimated by applying cBathy algorithm to July 2017 video imagery. Right: Bathymetry measured with sonar in February 2017.

Ultraviolet light gives desmid alga cell a bright red glow
This single-celled alga is a natural ornament
It looks like a holiday ornament, but this lovely object is a single-celled freshwater alga from the desmid family, found in the marshes of Florida’s Arthur R. Marshall Loxahatchee National Wildlife Refuge. USGS biologist Barry Rosen photographed it at 200x magnification using ultraviolent light and a fluorescence microscope.
