Integrating Science and Management for Optimal Prevention and Control of Invasive Nymphoides in Florida

Two invasive species of floating hearts, Nymphoides cristata and N. indica, are actively managed in Florida. A rare native species, N. humboldtiana, has been found in Florida and verified by molecular methods; this species is nearly indistinguishable from N. indica.

Hurricane Matthew: Flood Resources and Tools

During and after Hurricane Matthew, the USGS made flood-flow measurements, maintained streamgages, deployed over 390 instruments, and developed geospatial products to measure and communicate the extent of coastal and inland flooding.

Remote Sensing Coastal Change

We use remote-sensing technologies—such as aerial photography, satellite imagery, and lidar (laser-based surveying)—to measure coastal change along U.S. shorelines.

Joint Ecosystem Modeling: Alligator Production Probability Model

Because the American alligator (Alligator mississippiensis) is a keystone species of the Everglades ecosystem, managers need a way to quantitatively assess the effects of alternative restoration scenarios on alligators.

Sea turtle nesting on Eglin Air Force Base property, Cape San Blas, Florida

The Northwestern Atlantic population of loggerhead sea turtles is one of the largest in the world. Genetic studies have divided this population into 5 management units including a genetically distinct group that nests throughout the northern Gulf of Mexico (GoM).

Bird Banding Laboratory

The Bird Banding Laboratory (BBL) is an integrated scientific program established in 1920 supporting the collection, archiving, management and dissemination of information from banded and marked birds in North America.  This information is used to monitor the status and trends of resident and migratory bird populations. Because birds are good indicators of the health of the environment, the...

Heavy-Mineral Sand Resources in the Southeastern U.S.

We are assessing the extent of industrial mineral resources hosted by heavy-mineral sands in the coastal plain of the southeastern United States. “Heavy-mineral sands" (HMS) is a term commonly used in industry and geologic literature to describe layered sediments deposited in coastal environments that contain dense (“heavy") minerals of economic value. The heavy minerals extracted from these...

Microscopic image of cyanobacteria that show up red in fresh water
July 17, 2017

In fresh water, these red cyanobacteria don't absorb a green stain

This is the first of two microscopic images of potentially toxic cyanobacteria, Microcystis aeruginosa.  In both images, the cyanobacteria have been exposed to a green stain.

Image 1: Microcystis aeruginosa in freshwater. The green stain doesn’t enter the cells, which show up in red.

In salty water these cell walls absorb a green stain and turn green

This is the second of two microscopic images of potentially toxic cyanobacteria, Microcystis aeruginosa.  In both images, the cyanobacteria have been exposed to a green stain.
Image 2: Mycrocystis aeruginosa In water half as salty as seawater. The cell walls are breaking down and the stain has penetrated them, turning the colony green.

“Variance” image produced from video shot at Madeira Beach, Florida, on June 20, 2017. The more the light intensity changes at a given spot, or “pixel,” during the video, the brighter the value assigned to that pixel. Motion tends to produce changes in light intensity. Note bright bands parallel to shore where waves were breaking. Researchers are using these and other

A healthy coral reef at Buck Island, U.S. Virgin Island
April 20, 2017

In the first ecosystem-wide study of changing sea depths at five large coral reef tracts in Florida, the Caribbean and Hawai’i, U.S. Geological Survey researchers found the sea floor is eroding in all five places, and the reefs cannot keep pace with sea level rise. As a result, coastal communities protected by the reefs are facing increased risks from storms, waves and erosion.

The heavy rains and storm surge Hurricane Matthew produced caused severe flooding in many parts of the south east, resulting in almost 40 peak flood records. As the flood waters continue to recede from some affected areas, the U. S. Geological Survey will continue its efforts to record this historic flooding. Click here to learn more about the work the USGS has completed for Hurricane Matthew.
