UrduThe entire contiguous U.S. has experienced massive urban expansions and the Atlantic Coast shows outstandingly high rates. Urban expansion has substantially squeezed the space of tidal flats and affected surrounding environments. In new urban areas, tidal flats have undergone considerable degeneration with more significant patterns as they get closer to new urban locations. Tidal flats protect against the ocean’s destructive powers such as hurricanes. Without some inland spaces to move around, they will likely disappear, which will have dire consequences for beachfront communities.

How did ancient extreme climate affect sand in the deep sea?
Geologists are interested in the sedimentary cycle – erosion from mountains that forms sand that is carried out to the ocean – because it’s foundational for understanding how the planet works.
How do wild pigs affect riparian systems?
Rooting, soil erosion, and E. coli concentrations in streams among several issues
Mapping the Midwest’s soil topography
An Iowa State University agronomist is developing new computer models of soil erosion and topography changes, requiring both innovative big-data technology as well as painstaking validation of soil measurements in the real world. The National Science Foundation recently awarded Bradley Miller an early career development grant to support the research.
How does wind erosion affect farming in Washington state?
Windstorms, less organic matter on topsoil and soil degradation among issues

Corals Carefully Organize Proteins to Form Rock-Hard Skeletons
Charles Darwin, the British naturalist who championed the theory of evolution, noted that corals form far-reaching structures, largely made of limestone, that surround tropical islands. He didn’t know how they performed this feat. Now, Rutgers scientists have shown that coral structures consist of a biomineral containing a highly organized organic mix of proteins that resembles what is in our bones. Their study, published in the Journal of the Royal Society Interface, shows for the first time that several proteins are organized spatially – a process that’s critical to forming a rock-hard coral skeleton.
NAU geomorphologists map fine sediment in Colorado River ecosystem to improve long-term sandbar management
Matt Kaplinski, a senior research associate in Northern Arizona University’s School of Earth and Sustainability (SES), is the principal investigator on a project, “Long Term Monitoring of Sediment Resources and Channel Substrates of the Colorado River in Grand Canyon National Park,” designed to study how the sandbars in the river may be preserved through conservation management.
“Ghost Forests” Expanding Along Northeast U.S. Coast
Why are “ghost forests” filled with dead trees expanding along the mid-Atlantic and southern New England coast? Higher groundwater levels linked to sea-level rise and increased flooding from storm surges and very high tides are likely the most important factors, according to a Rutgers study on the impacts of climate change that suggests how to enhance land-use planning.
Land Development in New Jersey Continues to Slow
Land development in New Jersey has slowed dramatically since the 2008 Great Recession, but it’s unclear how the COVID-19 pandemic and efforts to fight societal and housing inequality will affect future trends, according to a Rutgers co-authored report. Between 2012 and 2015, 10,392 acres in the Garden State became urban land. That’s 3,464 acres a year – far lower than the 16,852 acres per year in the late 1990s and continuing the trend of decreasing urban development that began in the 2008 Great Recession.
Mangrove Trees Won’t Survive Sea-Level Rise by 2050 if Emissions Aren’t Cut
Mangrove trees – valuable coastal ecosystems found in Florida and other warm climates – won’t survive sea-level rise by 2050 if greenhouse gas emissions aren’t reduced, according to a Rutgers co-authored study in the journal Science. Mangrove forests store large amounts of carbon, help protect coastlines and provide habitat for fish and other species. Using sediment data from the last 10,000 years, an international team led by Macquarie University in Australia estimated the chances of mangrove survival based on rates of sea-level rise.

In Cuba, Cleaner Rivers Follow Greener Farming
For the first time in more than 50 years, a joint team of Cuban and U.S. field scientists studied the water quality of twenty-five Cuban rivers and found little damage after centuries of sugarcane production. They also found nutrient pollution in Cuba’s rivers much lower than the Mississippi River. Cuba’s shift to conservation agriculture after the collapse of the Soviet Union—and reduced use of fertilizers on cropland—may be a primary cause.
