The oceans cover 71% of the Earth's surface, yet we have only explored about 5% of it. However, with the help of technology, we have now been able to dive deeper and explore further into the unknown depths of the ocean.
Earth observation drones, also known as unmanned autonomous vehicles (UAVs), are one of the most promising technologies in the field of seafloor monitoring. These drones are equipped with advanced remote sensing Earth observation equipment such as sensors and cameras, which allow them to map the sea floor, track changes, and monitor marine life and habitats. They have the ability to reach areas that are otherwise impossible or dangerous for humans to reach. They are also more efficient and cost-effective than traditional methods of underwater exploration.
Owing to such vast applications and benefits, the Earth observation drones market is expected to grow significantly.
According to the BIS Research report, the global Earth observation drones market was valued at $9.01 billion in 2021, and it is estimated to reach $18.21 billion by 2032, growing at a compound annual growth rate (CAGR) of 6.88% during the forecast period 2022-2032.
In this blog, we will explore the latest developments in underwater monitoring using drones and aircrafts. We will take a closer look at how these drones are being used to predict and prevent natural disasters, monitor oil spills, detect pollution and illegal fishing activities, and improve our understanding of oceans’ ecosystems.
We will also discuss the recent advancements in underwater drone technology and how it continues to revolutionize seafloor monitoring.

A Look at the Latest Developments in Seafloor Monitoring and Exploration
Understanding earthquake danger requires accurate measurements of the Earth's crust's position and topography. Researchers from the Institute of Industrial Science at the University of Tokyo have now created a cutting-edge technique for tracking the location of the seafloor using Earth observation drone-based observation equipment that has the potential to revolutionize oceanographic observation.
Professor Yokota notes, "Measurement of the seafloor has typically been carried by utilizing buoys or ocean-going vehicles." He further states, "To produce precise positional data, seafloor stations must interact with ships or buoys at the surface, which in turn must communicate with satellites. However, the mobility and speed of surface vessels are constrained by oceanic conditions."
The team created a sea-surface landing UAV as a monitoring tool to help with some of these problems. The UAV, which hovers over the water's surface and communicates with stations for monitoring the seafloor, was equipped with lightweight measurement equipment. This system's benefits include how quickly and effectively it can gather data on the deep ocean bottom.
According to co-author Professor Hirakawa, "The mobility of this UAV means that it is possible to gather deep geodetic measurements much more swiftly and efficiently than before." "Such high-speed UAV observation in the sea would enable frequent marine biology and fisheries science observations, assist in the operation of autonomous underwater vehicles/remotely operated vehicles, and contribute to catastrophe prevention,” he further adds.
The team's next steps involve more seagoing UAV testing and the advancement of autonomous navigation and observation capabilities. Given the destruction that earthquakes and tsunamis may bring, precise data that can aid in the forecast, such as that obtained by UAVs, is essential.
How are drones transforming human understanding of the ocean?
Seafloor monitoring using Earth observation aircrafts and drones is an innovative approach to understanding and protecting the oceans. One of the most significant advantages of using drones for underwater monitoring is their ability to cover large areas in a relatively shorter amount of time. Traditional methods of underwater mapping and exploration, such as using manned submersibles or ships, are time-consuming and costly. Drones, on the other hand, can cover vast areas of the seafloor quickly and efficiently, providing researchers with a complete picture of the underwater environment.
One of the most important applications of underwater monitoring using drones is the prediction of natural disasters. For example, drones can be used to map the seafloor and monitor coastal erosion, which can help predict potential tsunamis and storm surges. They can also be used to detect underwater landslides, which can trigger tsunamis, and monitor volcanic activity, which can help predict eruptions.
Underwater monitoring using drones is also helping to protect our oceans from pollution and other human-caused impacts. In addition, drones are also helping to improve our understanding of the oceans’ ecosystems and the effects of climate change on marine life and habitats. Drones can be used to collect data on ocean temperature, salinity, and other important parameters, which can be used to better understand the ocean's role in the global climate.
Conclusion
In conclusion, the use of drones for seafloor monitoring is a rapidly growing field and has already shown to be very useful in many areas, such as mapping seafloors, detecting and monitoring oil spills and illegal fishing activities, and predicting natural disasters.
Sea floor monitoring technology is advancing quickly, and new developments such as hybrid drones, improved power systems, and machine learning algorithms are making it easier and more efficient to collect data and make accurate predictions about the ocean and its health.
As we continue to learn more about our oceans and the impacts of human activity on the ocean ecosystem, the use of drones for seafloor monitoring is expected to become increasingly important in protecting this vital resource for future generations.
