The researchers report that this nutrient stress affects microscopic marine organisms and could influence marine ecosystems over time.\r\n\r\nFrom 2002 through 2021, average sea-surface temperatures increased across nearly 90% of the ocean area examined in the study. Over the same period, nutrient stress generally intensified, consistent with previous hypothesis that warming oceans may become increasingly stratified and less able to replenish surface nutrients.\r\n\r\nLearn more in [this NASA feature](https://science.nasa.gov/earth/ocean-nutrient-stress/).",
