There's something different about the waves at Torrey Pines State Beach in California: they're pink, temporarily, of course. The coloring comes from a pink dye that's part of an experiment to research how small freshwater outflows interact with the surf zone where waves are breaking, said postdoctoral scholar Alex Simpson. The experiment will give scientists a first-ever look at how waves at the lagoon mix with buoyant plumes, or masses of fresher water that enter saline regions during river outflow, the team said.
