Executive Summary
Warming seas are expected to reshape phytoplankton chemistry, lowering protein and nutrient content in polar waters and affecting marine food webs
- Polar phytoplankton may lose up to 30 percent of protein under high emissions
- Carbohydrates and lipids are expected to rise as sea ice retreats
- Ocean circulation slowdown reduces nutrient upwelling in polar waters
- Subtropical and higher latitude phytoplankton abundance may drop by 50 percent
- A cellular allocation model links phytoplankton composition to light, temperature and nutrients
- Field measurements from Arctic and Antarctic regions already show more carb and lipid heavy cells
- Phytoplankton chemical releases also help shape surface ocean microbial carbon cycling
Quick Facts
- What: Climate change is altering phytoplankton composition and ocean carbon flow
- Where: Polar waters, subtropical gyres and the surface ocean
- Why: Warmer waters and weaker upwelling change nutrients, light and food quality
- Who: MIT, WHOI, Columbia and related marine researchers
- When: Under high emissions conditions through 2100

MIT researchers project that high-emissions warming through 2100 will reduce polar phytoplankton protein and nutrients as sea ice shrinks and nutrient upwelling weakens, shifting marine food-web chemistry.
Researchers use a cellular phytoplankton allocation model in a global ocean biogeochemical framework to project warming-driven changes in protein, carbohydrate, and lipid composition across polar and subtropical regions.
MIT researchers project sea ice loss and ocean warming will shift polar phytoplankton biochemistry by late century, lowering protein by up to 30%.
MIT researchers modeled how warming oceans and declining sea ice may shift polar phytoplankton macromolecular composition through 2100 in ways consistent with Arctic and Antarctic samples.
