The beard worms are packed with chemosynthetic bacteria that utilize the sulfate from the hydrothermal vents. These are hydrothermal vents, often considered among ⦠Primitive pumps that maintained the internal environment of primitive proto-cells may have allowed the earliest life forms to leave deep-sea hydrothermal vents for Earth's early oceans. I got the job at British Antarctic Survey second time round. Hydrothermal vents are the result of seawater percolating down through fissures in the ocean crust in the vicinity of spreading centers or subduction zones (places on Earth where two tectonic plates move away or towards one another). Watching Blue Planet II the other weekend gave me a huge amount of personal pride. I realised during that series that I wanted to be a scientist but not just any scientist, one that went to the Antarctic. Hot, mineral-rich fluids supply nutrient chemicals. This water is heated by radioactive decay from the planetâs continuous formation, appearing as ⦠The series covered the ebb and flow of the ice around Antarctica and the animals that depend on the productive waters of the Southern Ocean.
