The islands flanking the outlet of the Mississippi River are not only facing losses due to sea level rise and local subsidence, according to one study, but new unknown impacts from oil recovery operations, say researchers working on another project. Both will be presenting their work on Nov. 1 and 2 at the meeting of the Geological Society of American in Denver. Some islands could disappear entirely in coming decades, exposing huge swaths of marshland to the waves of the open sea. On one side...

By Lynn Arave Deseret News One of the most reliable indicators of an extra dry Great Salt Lake is the presence of a large sandbar that leads to Fremont Island.

The U.S. Corps of Engineers has been given the needed funding to complete dredging in the mouth of the Los Angeles River, upstream of the Queensway Bay Bridge. The dredging will prevent shoaling (sandy buildups on the ocean floor) from closing the channel from the Catalina Landing to the ocean. Beach-quality sand will be taken to a beach off Junipero Avenue and deposited in about 20 feet of water to help fight beach erosion. The Los Angeles River brings down several hundred thousand cubic...

SAN FRANCISCO (AP) - More than 2 square miles of some of the world's largest underwater sand dunes were mapped in the Pacific Ocean off the San Francisco coast as part of a study to help researchers better understand beach erosion. The submerged dunes, called sand waves, are located just west of the Golden Gate Bridge, measuring more than 30 feet high and 700 feet long, according to researchers with the U.S. Geological Survey. The sand waves were created by the displacement of sediment by...
