Why Does the Ocean Smell Like That?

The video explores the distinctive smell of the ocean, primarily caused by the breakdown of DMSP by microbes into DMS, which contains sulfur. Phytoplankton produce DMSP for protection and balance, but when consumed by predators, it becomes a food source for microbes. This process not only affects marine life but also plays a role in cloud formation and climate regulation. However, increasing ocean acidity due to CO2 emissions threatens phytoplankton growth and DMS production, highlighting the need for further research into these complex interactions.
