Caribbean-Florida Water Science Center Watercams for Florida
Webcams have been installed at several real-time stream-gaging sites. The webcams provide valuable information to the National Weather Service, emergency managers, and area residents to evaluate real-time conditions in river environments during storms. The visual record of flooding and other river events also provides valuable research data for the USGS. Many of these webcam installations are...
Water-Use in Florida
Consistent and accurate statewide water-use data are essential for the sound management of Florida's water resources. The five water management districts (WMD), which are the primary collectors of water-use information, tailor their water use programs to each of their own needs and priorities. Consequently, within the State, there are several different levels of data collection, storage,...

In order to explain the patterns of naturally-occurring drought, floods, and storms for the past, identified by...
Understanding Drivers of Cyanotoxin Production in the Lake Okeechobee Waterway
The U.S. Geological Survey (USGS) and other researchers combined field and laboratory approaches in two studies to understand the factors that drive cyanobacterial bloom development and associated cyanotoxin production in Lake Okeechobee, the St. Lucie River and Estuary, and the Indian River Lagoon in response to the large-scale Lake Okeechobee cyanobacteria bloom in 2016.
Late Pleistocene baldcypress (Taxodium distichum) forest deposit on the continental shelf of the northern Gulf of Mexico
Approximately 13 km south of Gulf Shores, Alabama (United States), divers found in situ baldcypress (Taxodium distichum) stumps 18 m below the ocean surface. These trees could have only lived when sea level fell during the Pleistocene subaerially exposing the tectonically stable continental shelf. Here we investigate the...
DeLong, Kristine L.; Gonzalez, Suyapa; Obelcz, Jeffrey B.; Truong, Jonathan T.; Bentley, Samuel J.; Xu, Kehui; Reese, Carl A.; Harley, Grant L.; Caporaso, Alicia; Shen, Zhixiong; Middleton, Beth Lipidomics reveals specific lipid molecules associated with cold stress syndrome in the Florida manatee (Trichechus manatus latirostris)
Cold stress syndrome (CSS) in the Florida manatee (Trichechus manatus latirostris) results in perturbations to many physiological pathways, often leading to further illness or death.

Griffin, Emily K.; Costa, Kaylie Anne; Aristizabal-Henao, Juan J.; Napolitano, Michael P.; Hunter, Margaret; Ferrante, Jason; Bowden, John A. Measuring coastal acidification using in situ sensors in the National Estuary Program
Estuaries and coastal areas are highly vulnerable to the impacts of acidification on shellfish, coral reefs, fisheries, and the commercial and recreational industries that they support. Yet, little is known about the extent of this vulnerability and the estuary-specific drivers that contribute to acidification, such as nutrient enrichment from...

Widespread Ranavirus and Perkinsea infections in Cuban treefrogs (Osteopilus septentrionalis) invading New Orleans, USA
Invasive species can negatively impact ecosystems in numerous ways, including vectoring pathogenic organisms. In amphibians, a lineage globally threatened by multiple pathogens, this spread of disease via invasive species could contribute to declines in native populations. The Cuban Treefrog (Osteopilus septentrionalis) is invasive in the...

Haider, Saira M.; Romañach, Stephanie S.; McKelvy, Mark; Suir, Kevin J.; Pearlstine, Leonard The value of US coral reefs for flood risk reduction
Habitats, such as coral reefs, can mitigate increasing flood damages through coastal protection services. We provide a fine-scale, national valuation of the flood risk reduction benefits of coral habitats to people, property, economies and infrastructure. Across 3,100 km of US coastline, the top-most 1 m of coral reefs prevents the 100-yr flood...

New low-altitude aerial photos of Southeastern beaches taken before and after Hurricane Matthew passed offshore show a new storm-cut inlet, and roads, dunes and structures lost.
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.
