Overview
The Sealite SL-15 compact LED marine light is an exceptional value and incorporates some of the most advanced technology available. In the tradition of Sealite lanterns, the SL-15 is designed to be maintenance-free with a life expectancy of up to 12 years, with battery replacement approximately every 5 years.
Reactive
The SL-15 can be installed in minutes. Once the flash code is set, no operator intervention is required. The solar module will charge the replaceable battery during daylight hours, and the lantern will automatically begin operation at dusk. The SL15 features the Sealite LED 360 Omni Directional Reflector, which increases the intensity and uniformity of the horizontal output.
Built for Nature
The tough polycarbonate lens is specifically designed for use with LEDs and has an environment-friendly spike deterring unwelcome birdlife. The unit is sealed using an advanced ultrasonic weld, enabling a rugged waterproof seal capable of prolonged and deep immersion (IP68)

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.

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.
Read MoreSoundscapes 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.
