Global phytoplankton decline over the past century
The two main objectives of the research were to examine global trends in phytoplankton over time and to determine what might be driving these trends. Preliminary conclusions suggest that rising ocean temperatures are the leading cause of the decline. “As the water temperature rises, the ocean becomes more stable which limits the nutrients present in the water. This in turn limits the amount of phytoplankton,” explains Mr. Boyce.
Based on the research collected, phytoplankton levels have decreased in eight out of 10 ocean regions.
