1978, Massachusetts developed a 127-acre reef of 2,500 concrete-filled tire bundles in Nantucket Sound; a 2019 survey found fish arrived in about 33 seconds at reefs versus nearly eight minutes over bare sandNearly fifty years ago, Massachusetts introduced tire reefs to enhance marine ecosystems. Recent research indicates that these structures n...

In June 2026, El Niño weakened Pacific trade winds, shutting down nutrient-rich upwelling; satellites then watched phytoplankton decline, threatening anchovies and seabirds as the ocean food chain began to unravelEl Niño has returned to the Pacific Ocean in June 2026, impacting marine ecosystems. Weakened trade winds are reducing nutrient upwelling, ...
In 2010, researchers tested solar panels with white lines; the modified surfaces were up to 26 times less attractive to polarotactic insectsSolar panels, with their shiny surfaces, can inadvertently attract insects seeking water. This phenomenon leads to ecological harm, disrupt...

In 2011, USGS researchers began studying Lake Erie's fish and seasonal hypoxia across a multi-year project. 15 years later, the findings showed fish crowding areas near 2–3 mg/L oxygen, revealing an unexpected shift at the edges of low-oxygen zonesLake Erie’s seasonal hypoxia is changing where fish gather. For years, scientists watched oxygen levels fall and fish move around the lake....
