Extreme rainfall is worsening algal blooms along South Korea's coast

Extreme rainfall is reshaping coastal waters along South Korea's shoreline, flushing nutrients from land into the sea and fueling the growth of algal blooms. A new multi-year study, published in Frontiers in Marine Science, tracked water quality in and around a major river estuary and shows how intense downpours can shift where and when these blooms appear, with consequences for marine ecosystems and coastal communities.
