How Ocean Chemistry Affects Global Climate & Vice Versa | GEO GIRL

Ever wonder what Earth's oceans are made of, how they got to their current composition, salinity, and pH, how they are currently changing, and how they've changed through time? In this video, we go over how the oceans formed and became salty, how their salt content has changed through time and space, how nutrients are cycled in the oceans, and how gases are cycled between the ocean and atmosphere. Currently, the global chemistry of Earth's oceans is changing due to climate change, and we discuss these changes and their potential consequences at the end of this video.
