Water quality issues are shifting in the United States’ rivers in big ways.
Those changes are driven, in part, by the way the land in a watershed is used and they’re big enough that researchers may need to change the way they think about water quality in the American rivers.
“What was striking to us was how perceptions of water quality issues from several decades ago may need to be updated,” said Edward Stets, a U S Geological Survey research ecologist, in an email response to questions from Environmental Monitor.
New research by Stets published in Environmental Science &; Technology in March highlights these shifting water quality issues.Read More
The start of Duke University’s oceanographic mooring line doesn’t begin at the surface of the ocean, but 500 meters beneath it. Floating at the top of the mooring system is a 64-inch syntactic sphere with 2,500 Lbs of buoyancy. It serves a duo of roles as both a floatation device and housing for two high-end acoustic monitoring systems.
Next comes 75 meters of chains and wires before coming to two ocean current profilers, one pointing up and the other pointing down. Next to that equipment are two instruments that measure temperature and salinity.
Next comes several hundred more meters of wire before arriving at several glass balls, more floatation orbs.Read More
This spring, palm warblers, rose-breasted grosbeaks, tree swallows and great blue herons fill Muskegon Lake Nature Preserve with their songs or stately presence.
In 1997, the preserve was a dump.
The community partnerships and restoration efforts that turned a dump in one corner of Muskegon Lake in west Michigan into a haven for plants, wildlife and recreational fishers ran parallel to other efforts around the lakeshore and the Great Lakes since 1985.
In 1985, the United States and Canada chose to focus environmental cleanup efforts on 42 highly polluted areas of concern (AOCs ) around the Great Lakes, including Muskegon Lake.
Thirty-five years later, that decision has changed environmental remediation and benefited Great Lakes communities.Read More
