DMS is a chemical that is broken down from DMSP (dimethylsulfoniopropionate), which is in the cells of phytoplankton and bacteria which helps them withstand the salty oceans. Then when the plankton dies DMSP is released into the water and is quickly broken down, 76% of it becomes methanethiol and the majority of the leftover becomes DMS. After the DMS is released into the water, 90% stays there and a small amount goes into the atmosphere, which is about 3 billion grams of it every hour across the world's oceans, which is gives the ocean it's signature scent. In the atmosphere it lasts a max of 2 days, then it oxidizes and turns into sulfate aerosols (tiny particles that are solid or liquid suspended in air), water vapor will condense around the particles which makes clouds form. Clouds reflect solar radiation back into space and provide a cooling effect which is very good for the planet. The amount of DMS that is released is supposed to equal the amount of CO2 that humans release, combating climate change but with the increasing amount of released CO2, it surpasses DMS.
