This multi-color view of the same sample offers insights into biofouling—or growth of living matter on objects submerged in water. Biofouling is a significant problem that negatively impacts shipping, offshore energy production, sensor performance, and medical and food safety. A research team at Pacific Northwest National Laboratory is developing improved methods for biofouling detection and quantification. The team submerged a fiberglass square in a seawater flow tank at PNNL’s Marine Sciences Laboratory for six weeks, then stained the square (upper left image) and photographed it. A novel digital image analysis method that included color separation was applied. The resulting red, green and blue perspectives each revealed unique, useful information and made it possible to quantify tube worms, sea sponges, and microorganisms on the surface. The project was funded by PNNL’s Chemical Imaging Initiative.
