Coastal erosion threatens archaeological sites along Greenland’s fjords
Hundreds of archaeology sites lie along the shores of Greenland’s fjords and coasts, revealing the entirety of the country’s ancestral cultures from as many as four thousand years ago. Coastal erosion, however, may soon drop many of those ancestral links into the ocean.

Increases in wildfire-caused erosion could impact water supply and quality in the West
A growing number of wildfire-burned areas throughout the western United States are expected to increase soil erosion rates within watersheds, causing more sediment to be present in downstream rivers and reservoirs, according to a new study.

Study finds pond expansion a significant factor in loss of Mississippi delta land
Wind-driven expansion of marsh ponds on the Mississippi River Delta is a significant factor in the loss of crucial land in the Delta region, according to new research. The study found 17 percent of land loss in the area resulted from pond expansion, much of it caused by waves that eroded away the edges of the pond.

Fungi make steep slopes more stable
Fungi are fantastic. They give us beer, bread and cheese. And if those delicious reasons aren’t sufficient, then here’s another: a new study suggests some fungi can help prevent shallow landslides and surface erosion.

Post-wildfire erosion can be major sculptor of forested mountains
Erosion after severe wildfires can be the dominant force shaping forested mountainous landscapes of the U.S. Intermountain West, new research suggests. After the 2011 Las Conchas fire in New Mexico, soil and rock eroded from burned watersheds more than 1,000 times faster than from unburned watersheds nearby, the new study found. Most of the erosion happened in the first year after the fire.

Ravenous goats muddy the waters
The Hawaiian island of Molokai is making a mess of its south shore reef. Every time it rains, gray ashy soil from the ancient volcanoes that formed the island wash downhill to the shore below and pollute the reef.
