London. Scientists are studying the ocean to predict how the climate will change in the future. In 2017 the Nippon Foundation launched the Jebco Seabed 2030 project. Under this, the goal of measuring the depth of the ocean around the world was set.
Now three years later, scientists have completed measuring 19% of the world's ocean. However, the work that is left on their part is that the area is so large that two Mars can easily fit into it. The diameter of the Earth is 12,750 km while that of Mars is 6,790 km. In the last three years, scientists have completed the fifth part of the sea surface i.e. measuring 16.5 million sq km.
Using spacecraft altimeter equipment to measure the depth
Jamie McMichael Phillips, director of the Seabed Project, says that we use a special type of spacecraft altimeter instrument to measure the depth of the ocean. We use this technique to lay underwater cable lines, sea navigation, and fisheries management or to save the life of fishermen. The world's greatest diversity exists below sea level, much larger than land.
With the study of the sea surface, we are researching the effect of ocean water flow and oceans controlling the temperature of the Earth on climate change. We are figuring out where the sea water will grow in the future so that we can do its surface mapping correctly.
British-American company Ocean Infiniti has built a robotic ship to measure the sea surface, which will also measure the distance from the seashore to remote locations. This will ease the companies laying cabling in the sea. Jebco is an intergovernmental institute, working together to measure the depth of the ocean in the world.
The depth of the sea surface is measured by creating ultrasonic waves
Scientists send ultrasonic waves inside the ocean to find the ocean depth, which collides with the surface and gets reflected. The depth of the ocean is measured by acquiring these waves by halving the time it takes for them to leave and return.
