One agricultural network was 5 times larger than earlier estimates, and the fields may be an early source of human-caused greenhouse gas emissions.
Researchers say it’s the oldest-known living tree in eastern North America. If it hadn’t been protected, it could have ended up as garden mulch.
Dissolved organic matter supports aquatic food webs and holds as much carbon as the atmosphere. A new study tracks which sources and processes play the biggest role in coastal systems.
A new model improves predictions for sediment movement in vegetated shoreline zones and reveals a universal predictor that could change the understanding of coastal landscape evolution.
Grain size and sediment delivery pathways from the Ganges delta have been used to model downstream facies changes.
Brackish wetlands and their salt-tolerant vegetation are significant methyl halide emitters. The natural emissions add chlorine and bromine to the stratosphere, which break down ozone.
Canals, dammed reservoirs, irrigation ditches, and pollution are changing species diversity, microbial communities, and nutrient levels in aquatic zones across the planet.
A 3-year study of wetlands and cropland in a major California delta highlights the need to consider the physical effects of vegetation when planning land use changes.
NASA Workshop on Remote Sensing of Inundation Extent; Boulder, Colorado, 21–22 May 2018
Satellite-based optical sensors can detect, measure and monitor changes in lakes, reservoirs, rivers and wetlands, providing useful data with multiple applications for science and society.
