What do we really know about the ocean? How much has it been studied today? What is happening to the ocean due to global warming? How does plastic affect living things? What do we know about life in the Mariana Trench? Can coral reefs be saved? And why does the ocean still remain a mystery to science? Oceanologist Alexander Osadchiev, marine biologist and head of the diving team at the White Sea Biological Station at Moscow State University Alexander Semenov, and head of the hydrobiology laboratory at the Center for Marine Research at Moscow State University Alexander Kokorin helped to understand these questions.
