Phytoplankton are tiny, single-celled organisms mainly found in the ocean’s sunlit surface, where they grow through photosynthesis, forming the marine food web’s base and regulating Earth’s climate by absorbing carbon dioxide. Their seasonal growth cycles—known as “blooms”—drive marine productivity and influence everything from carbon uptake to food security. But how can we track ...[Read More]
