Coral reef expert Caroline Rogers was the only USGS employee in the Virgin Islands when the Category 5 storm hit.
A study finds that although the “wilderness breach” created by Hurricane Sandy in 2012 has reached a relatively stable size and location, the channel and shoals will keep changing in response to weather. Related research shows the breach isn’t likely to increase storm-tide flooding in Great South Bay.

Understanding the effect of salinity tolerance on cyanobacteria associated with a harmful algal bloom in Lake Okeechobee, Florida
In an effort to simulate the survival of cyanobacteria asthey are transported from Lake Okeechobee to the estuarinehabitats that receive waters from the lake, a bioassayencompassing a range of salinities was performed. An overalldecline in cyanobacteria health in salinity treatments greaterthan 18 practical salinity units (psu) was indicated by...

Land area change in coastal Louisiana (1932 to 2016)
Coastal Louisiana wetlands are one of the most critically threatened environments in the United States. These wetlands are in peril because Louisiana currently experiences greater coastal wetland loss than all other States in the contiguous United States combined. The analyses of landscape change presented here have utilized historical surveys,...

Assessing welfare of individual sirenians in the wild and in captivity
Assessing the welfare of wild populations of sirenians has required a “generalist” approach. The outcome has been a subjective decision as to whether what the observers are witnessing in an individual or group of animals is normal and whether that has positive or negative consequences. The understanding of sirenian welfare requirements, and a...

Pilot Testing and Protocol Development of Apple Snail Suppression at Mandalay National Wildlife Refuge
The maculata apple snail (Pomacea maculata) has invaded many coastal and some inland areas in south Louisiana.

A Website Tool for Predicting Triploidy in Larval Fish Spawns
Differentiating diploids from triploids at the earliest life stage possible allows for a more efficient use of resources including production time and rearing space. Thus, a reliable flow cytometric (FCM) method has been developed to discriminate triploids from diploids at the larval stage. In order to help simplify the process of differentiating triploids from diploids, we propose a simple...

Sparta Aquifer Recovery Project
The Sparta aquifer is Union County's only source of municipal and industrial ground water. Since development began in the early 1920's ground-water levels have declined more than 390 feet in some areas. As a result, Union was among five southern Arkansas counties designated as the state's first "Critical Ground Water Area" in 1996.

There are three extant sirenian species of the Trichechidae family and one living Dugongidae family member.

In the wild, they are exposed to...

Host-dependent differences in resource use associated with Anilocra spp. parasitism in two coral reef fishes, as revealed by stable carbon and nitrogen isotope analyses
The role of parasites in trophic ecology is poorly understood in marine ecosystems. Stable isotope analyses (SIA) have been widely used in studies of trophic ecology, but have rarely been applied to study the role of parasites. Considering that some parasites are associated with altered host foraging patterns, SIA can help elucidate whether...

USGS Hurricane Preparedness
Before a hurricane, USGS Scientists undertake a data collection effort of a grand scale. They install a temporary mobile network of sensors along the coasts to collect additional data on the intensity of storm surge, one of the most dangerous elements of a hurricane. This effort provides critical information that allows various USGS partners and emergency responders to
