The robots listen to what the ocean can tell about climate change. We improve their hearing
Robots and small submarine vessels are bringing us closer to life under water. They carry echo sounders to collect information. When they can carry several echo sounders with more frequencies, new possibilities to understand the oceans are opened up. Read more in the original blog…
Potential improvement in sonar seabed mapping
Today, a significant part of the oceans remains coarsely mapped. Some specific areas like the continental shelves will require high-resolution surveys. This represents a very long and expensive task that will keep scientist busy for several decades. A way to reduce costs and time could be to improve the efficiency of current surveys. We are trying to do this by sending more signals in the water at the same time.
The Multi-beam echo sounder is recognized as one of the most efficient and reliable tool for seabed mapping. Applications range from regional mapping of the seabed for geological surveys to the inspection of man-made objects such as pipelines or ship wrecks.
