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.

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...
Cahoon, Donald R.; McKee, Karen L.; James Morris Effects of water level alteration on carbon cycling in peatlands
Globally, peatlands play an important role in the carbon (C) cycle. High water level is a key factor in maintaining C storage in peatlands, but water levels are vulnerable to climate change and anthropogenic disturbance. This review examines literature related to the effects of water level alteration on C cycling in peatlands to summarize new...
Zhong, Yehui; Ming, Jiang; Middleton, Beth A global biophysical typology of mangroves and its relevance for ecosystem structure and deforestation
Mangrove forests provide many ecosystem services but are among the world’s most threatened ecosystems. Mangroves vary substantially according to their geomorphic and sedimentary setting; while several conceptual frameworks describe these settings, their spatial distribution has not been quantified. Here, we present a new global mangrove...
