New USGS Map Identifies Non-Native Aquatic Species Potentially Spread by Hurricane Isaias Floodwaters
The USGS has released the initial Flood and Storm Tracker (FaST) map for Hurricane Isaias, the Category 1 storm that swept up the mid-Atlantic coast last week.
Seafloor Methane Seeps at the Edge of Hydrate Stability
In June 2019, USGS scientists led a 22-day deep-sea research expedition aboard the R/V Falkor to examine methane seep dynamics and processes along the Cascadia Margin offshore of Washington and Oregon.

Growth rates for immature Kemp’s ridley sea turtles from a foraging area in the northern Gulf of Mexico
Examining vital rates helps clarify how environmental characteristics, biological resources and human activities affect population growth. Carapace lengths were gathered for 241 Kemp’s ridley Lepidochelys kempii sea turtles that were marked and recaptured (n = 23) between 2011 and 2019 at a foraging location in northwest Florida, USA....
Lamont, Margaret; Johnson, Darren Modeling soil porewater salinity in mangrove forests (Everglades, Florida, USA) impacted by hydrological restoration and a warming climate
Hydrology is a critical driver controlling mangrove wetlands structural and functional attributes at different spatial and temporal scales. Yet, human activities have negatively affected hydrology, causing mangrove diebacks and coverage loss worldwide. In fact, the assessment of mangrove water budgets, impacted by natural and human disturbances,...
Zhao, Xiaochen; Rivera-Monroy, Victor H.; Wang, Hongqing; Xue, Zuo; Tsai, Cheng-Feng; Willson, C. S.; Castañeda-Moya, E.; Twilley, Robert R. How plants influence resilience of salt marsh and mangrove wetlands to sea-level rise
This review evaluates the importance of plants and associated biological processes in determining the vulnerability of coastal wetlands to sea-level rise. Coastal wetlands occur across a broad sedimentary continuum from minerogenic to biogenic, providing an opportunity to examine the relative importance of biological processes in wetland...
