Ice Core Insights: A Comprehensive Look at Phytoplankton Trends Over 800 Years

A recent study published in the Proceedings of the National Academy of Sciences examines how marine phytoplankton throughout the North Atlantic Ocean has maintained its stability and numbers based on ice cores dating as far back as 800 years, which contradicts a 2019 study that concluded marine phytoplankton was on the decline by approximately 10 percent. The reason ice cores were examined was due to the methanesulfonic acid (MSA) deposits that fall from the sky and are the airborne products of phytoplankton, with the MSA initially starting off as…
