USGS-led Study: Shoreline Seasonality of California’s Beaches
One common pattern of beach morphology is the seasonal cycle of the shoreline. Shorelines often show cycles of erosion and recovery year after year, which results in recurring widening and narrowing of the beach. Scientists know that these cycles are related to ocean waves, and that larger waves cause movement of beach sand offshore whereas smaller waves move this sand back to the beach. Knowledge of these seasonal cycles comes from a long history of scientific measurement of beaches, and a general consensus is that beaches erode during winter conditions and recover during the summer. These descriptions of winter and
New study reveals insights into Yellowstone Volcanic System’s Hidden Magma Reservoirs
HILO, Hawaii — Researchers from the U.S. Geological Survey and Oregon State University examined the area beneath Yellowstone Volcanic system finding that although an eruption is unlikely anywhere in the area, changes to the northeast area of the volcanic system will be the key to understanding future eruptions. Scientists at USGS mapped underground areas containing magma in this volcanic system. Understanding where magma is located is essential for predicting volcanic activity and keeping the public informed about potential risks. This study gave a clear picture of how magma is distributed through the crust at Yellowstone using a method that is most sensitive
Cost-benefit study confirms coral reef restoration could be a cost-effective way to save lives and money
Researchers developed a modeling system to quantify the value coral reef restoration could provide to 1,000 kilometers, or 621 miles, of coastline in Florida and Puerto Rico. The research compared how much flooding storms could cause with and without coral reef restoration at a 10 square meter, or 108 square feet, resolution. Researchers then determined how many people and how much property and economic activity reef restoration could protect by preventing coastal flooding. "Coral reefs are natural coastal barriers that can substantially reduce coastal flooding and erosion,” said Curt Storlazzi, lead author and research geologist from the U.S. Geological Survey.
