Wetland Word: Blue Carbon
Coastal ecosystems, like wetlands, may be smaller in size when compared to say, a forest, but they have the ability to sequester more carbon per unit area, making them an incredible climate change mitigation tool
Wetland Science at WARC
This month we’re recognizing American Wetlands Month by sharing USGS Wetland and Aquatic Research Center (WARC) wetlands research along the Gulf of Mexico, throughout the Southeast, and around the world.
Wetland Word: Sequestration
Scientifically speaking, sequestration refers to the capture and storage of an element, like carbon, in the environment.

Synthetic aperture radar and optical mapping used to monitor change and replacement of Phragmites australis marsh in the Lower Mississippi River Delta, Louisiana
Synthetic aperture radar (SAR) mapping of density as an enhancement of Phragmites australis optical live fractional cover (LFC) mapping was carried out in the lower Mississippi Delta during 2016 to 2019. Also, as part of the study, the replacement of P. australis with elephant-ear was analyzed. To that end, yearly maps from 2016 to 2019 of L-band...

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...
