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 strange sea life. Scientists want to know why this part of the Atlantic Ocean attracts so many marine animals.
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(浮游生物) and fish. He adds that other sensing devices measure water currents and other features of sea life.
Another vehicle is powered by solar panels and a wind turbine. It can stay afloat for months. The robotic vehicle sends information about the so-called biodiversity hotspots. A biodiversity hotspot is an area of an ocean that has a lot of plant and animal life activity.
Lavinia Suberg is one of the scientists studying the biodiversity of the Celtic Sea. She says productive ocean areas, like the Celtic Sea, attract zooplankton. The zooplankton then attracts fish. She adds that areas with a large increase of fish often attract sea mammals and birds.
Using these robotic ocean vehicles greatly reduces the cost of exploring the seas with manned laboratories. Scientists can spend more time analyzing the collected information. They say the research will give them a better understanding of the needs of the Celtic Sea for future management and protection.
