## In brief

- Warming oceans can intensify seawater stratification, creating layers of water that mix less readily.
- Reduced mixing can limit the nutrient supply that supports phytoplankton at the base of the marine food web.
- The source is a short summary; further details are truncated in the provided text.

## Why it matters

Changes at the base of the marine food web affect the productivity and structure of ocean ecosystems that science readers study and monitor.
