Plankton in coastal waters can tell us a lot about the health of marine ecosystems and fisheries. By using advanced imaging technology called PlanktonScope, scientists studied how physical and biological factors affect plankton over time. They found that daily cycles, seasonal changes, and big events like typhoons all play a big role in plankton dynamics. The data from PlanktonScope gives us a clear picture of what's happening in the ocean at different times and places, helping us understand how plankton move and change in response to their environment. This technology could be a valuable tool for monitoring plankton in real-time and learning more about their behavior.
