Road salt runoff flowing into streams near Cornell approaches ocean-like salinity
Salt applied to roads during the winter has an unsettling tendency to stick around long after the ice has melted. What’s more, it can make the runoff flowing into nearby streams almost as salty as the ocean, according to a recent study. 
 
A student-led effort at Cornell University made the discovery after another investigation looking into nitrogen concentrations uncovered oddly high conductivity levels in a plot of soil near a campus parking lot. Researchers say the results of the investigation will help fill in the blanks in long-term data sets on chloride levels in streams near Ithaca, New York, and may help to start a conversation on tackling problems that road salt creates.

Most people go to Lake Champlain for its exceptional views and thrilling boating, but it’s also home to a wide variety of interesting aquatic research projects. From studying microplastics to thermal dynamics of the lake, Timothy Mihuc, director of the Lake Champlain Research Institute (LCRI) at the State University of New York at Plattsburgh (SUNY Plattsburgh), has spent his career studying aquatic ecosystems. 
 
 As an aquatic biologist, he’s the main investigator on Lake Champlain’s research studies while also managing their grants, employees, and their hands-on buoy work. 
 
 Over the years, LCRI has received a number of environmental grants that aid in its monitoring research.

On March 26th, according to The Baltimore Sun , a 984-foot, 112,000-ton Dali lost propulsion and collided with a support column of the Francis Scott Key Bridge, collapsing the structure. Soon after the event, search and rescue, salvage crews, and other emergency responders were mobilized after the collision. 
 
As salvage efforts progressed in early April, NOAA’s Center for Operational Oceanographic Products and Services (CO-OPS) responded to a request for real-time tidal currents data and deployed a current monitoring buoy—CURBY (Currents Real-time BuoY)—into the Patapsco River north of the Francis Scott Key Bridge.
