Ash from the Los Angeles Palisades and Eaton fires has been found by ocean researchers up to 100 miles away in the Pacific near San Nicolas Island.

San Diego scientists are collecting samples of ash from California's coast to measure how toxins and urban debris from the Los Angeles wildfires could affect nearby fisheries and the food webs of local ecosystems.

The wildfires in Southern California in January aren't just harmful to humans. Researchers are now looking at the falling ash that blows over the ocean.
