Most of the oxygen in the atmosphere originally came from photosynthetic organisms in the ocean, known as phytoplankton and mixoplankton . To understand how plankton live, grow, and help our planet, and how climate change might affect them, scientists at Plymouth Marine Laboratory: Take samples from the sea Use satellites to look at the ocean from space Do experiments in the lab Use computers to make models and predictions. Climate and the Ocean Science Story Fun fact! Above: Scientists looking at microscopic images of plankton at Plymouth Marine Laboratory.
