Scientists in England are using two self-directed water vehicles to explore the animal and plant life of the Celtic Sea. The Celtic Sea is a body of water off the southern coast of Ireland. The area is known for its exceptional sea life. Scientists want to know why marine animals are so attracted to this part of the Atlantic Ocean. One of the research vehicles is powered by batteries. It collects information for the National Oceanography Center in Southampton, England, and the World Wildlife Fund. The vehicle’s low energy requirements permit it to stay afloat for up to 30 days. Reports of what it finds in the Celtic Sea are sent by satellite. Stephen Woodward is an engineer who helped design the craft. He says the vehicle has equipment that can detect small organisms called zooplankton and fish. He says other devices measure water currents and other features of sea life. There is also a device that creates a two-dimensional map of the sea. Another research vehicle is powered by solar panels and a wind turbine. It can stay afloat for months. The robotic vehicle sends information about biodiversity hotspots. A biodiversity hotspot is an area of an ocean that has a lot of plant and animal life activity. Robotic ocean vehicles greatly reduce the cost of exploring the seas with manned laboratories. Scientists have more time to examine the collected information. The research will help them understand the needs of the Celtic Sea in order to protect and manage its future.
