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 WorldWildlife 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 adds that other sensing devices measure water currents and other features of sea life. The vehicle also creates a two-dimensional map of the sea.
Another vehicle is powered by solar panels and a wind turbine. It can stay afloat for months.
