Researchers have discovered that a common type of ocean algae is responsible for producing a vastly abundant compound that significantly aids in cooling the Earth’s climate. This compound, known as DMSP, is crucial for climate regulation, suggesting that levels of DMSP and its byproduct DMS might be higher than previously anticipated, impacting global climate cooling.

The researchers identified the bloom-forming Pelagophyceae algae as potentially abundant and important producers of a compound called dimethylsulfoniopropionate, or DMSP. Dr. Jinyan Wang, OUC/UEA PhD student and first author, said: “Understanding the role of Pelagophyceae in DMSP production means we need to rethink how much of this compound is being produced and how it impacts our climate.”Every year, billions of tonnes of DMSP are produced in the Earth’s oceans by marine microorganisms, helping them to survive by protecting against various stresses like changes in salinity, cold, high pressure, and oxidative stress.
When DMS is released into the atmosphere, DMS oxidation products help form clouds that reflect sunlight away from the Earth, effectively cooling the planet. Dr. Curson said: “The identity of these enzymes allowed our team to identify Pelagophyceae as potentially abundant and important DMSP producers.”
