Biological evaporation effect by phytoplankton on stable isotopic signatures of water

Key Points

• Stable isotopic signatures of water are altered by biological evaporation effects from phytoplankton.
• Notable changes in isotopic composition were observed in different water samples due to phytoplankton activity.
• Analysis across various aquatic environments showed consistent patterns in isotopic signatures linked to evaporation levels.
• This work highlights the need for understanding biological factors in water isotopic studies to inform ecological research.
