Researchers have developed a DNA-based tool that can detect red tide algae when only a few cells are present

bar chart comparison of growth and grazing for Karenia brevis and the whole phytoplankton community during the study period.NCCOS-supported researchers have developed a DNA-based tool that can detect #RedTide algae even when only a few cells are present. By allowing precise, species-specific detection of harmful algae at very low levels, the method supports earlier detection, improved tracking, and a clearer understanding of the biological processes that drive red tide events. https://coastalscience.noaa.gov/news/new-dna-method-detection-of-red-tide/
