Overview
Bright Dyes act as a coloring label on each drop of water. As that water or liquid travels, it can be identified at each point on its travel until it reaches extreme dilution. It may be detected visually, by ultraviolet light and by appropriate fluorometric equipment. The dyes selectively absorb light in the visible range of the spectrum. They are fluorescent because, upon absorbing light, they instantly emit light at a longer wavelength than the light absorbed. This emitted (fluorescent) light goes out in all directions. Most common fluorescent tracers are compounds that absorb green light and emit red fluorescent light.
Absorption Resistant
FWT red dye is resistant to absorption on most suspended matter in fresh and salt water. Compared to Bright Dyes FLT Yellow/Green products, FWT Red is significantly more resistant to degradation by sunlight and, when used in fluorometry, stands out much more clearly against background fluorescence.

Climate Change and Microplastics: Monitoring Lake Champlain
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.

Current Monitoring after the Francis Scott Key Bridge Collapse
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.

Soundscapes of the Solar Eclipse: Citizen Science Supporting National Research
On April 8, 2024, millions of people around the world had their eyes glued to the sky to witness a historic cosmic event. The total solar eclipse captured the headlines and the minds of many who became eager to gaze at the heavens as the sky went dark for a few minutes. However, not everyone used their sense of sight during the eclipse, some were listening to the sounds of the natural world around them as the light faded from above. The Eclipse Soundscape Project is a NASA-funded citizen science project that focuses on studying how the annular solar eclipse on October 14, 2023, and the April 8, 2024 total solar eclipse impacted life on Earth. The project revisits an initiative from the 1930s that showed animals and insects are affected by solar eclipses.
