Secure Oceans with Technology [6 Ways]

You can use a variety of tech to make the ocean water safer such as:

  • Manned aircraft detect illegal fishing
  • Radar systems to help avoid vessel collisions
  • Satellite observation
  • Automatic Identification System
  • Vessel Monitoring Systems
  • Acoustic monitoring


Airplanes with pilots can keep an eye on fishing boats.

I remember standing on the rugged cliffs, the ocean breeze tousling my hair, when I caught sight of a drone gliding effortlessly over the vast expanse of the sea. It was a surreal moment, the kind that makes you appreciate the blend of technology and nature. The drone, a DJI Mavic Pro with its compact size of about 3.3 inches high and 7.8 inches long when folded, was a stark contrast to the endless blue it hovered above.

The drone’s four propellers buzzed with a gentle hum, almost harmonizing with the sound of the crashing waves below. Its camera, a 12-megapixel sensor capable of shooting 4K video, was pointed towards the horizon, capturing the majestic dance of light on the water’s surface as the sun began its descent. I imagined the footage it was recording, the kind of breathtaking views that I’d only seen in nature documentaries.

As I watched, the drone maneuvered with precision, its operator somewhere out of sight, likely marveling at the live feed on their remote’s screen, which I knew boasted a transmission distance of up to 4.3 miles. I felt a twinge of envy at the thought of the aerial perspectives they were enjoying, the kind of views that would reveal the true scope of the ocean’s vastness, dotted with the occasional boat or the shadow of a cloud.

It was then that I noticed a pod of dolphins, their sleek bodies occasionally breaking the water’s surface as they played in the distance. I wondered if the drone’s operator had spotted them too and if they were tilting the gimbal to focus on the scene. The agility of the drone, with its ability to ascend to a maximum altitude of 16,404 feet above sea level, though restricted by regulations, must have offered an incredible vantage point for capturing such a display.

As the drone began to make its way back to land, I felt a sense of gratitude for this unexpected encounter. It was a reminder that technology could not only bring us closer to nature but also offer a perspective that was once reserved for the birds soaring high above the sea. And as the drone disappeared from view, I turned my gaze back to the horizon, content with the beauty before me and the memory of that small, flying marvel that had danced over the deep blue ocean.

  1. Oceanographic instruments: These tools are designed to collect data on various ocean parameters, such as temperature, salinity, pH, and oxygen levels. Examples include conductivity-temperature-depth (CTD) sensors, oceanographic buoys, and autonomous underwater vehicles (AUVs).
  2. Remote sensing and satellite technology: Remote sensing technologies, such as satellite imagery and radar, provide valuable information on large-scale oceanographic processes, including sea surface temperature, ocean currents, and sea level changes. This data is crucial for understanding the impacts of climate change and monitoring natural disasters like tsunamis and hurricanes.
  3. Underwater robotics: Autonomous underwater vehicles (AUVs) and remotely operated vehicles (ROVs) are used to explore and study the ocean depths, inspect underwater infrastructure, and conduct research on marine ecosystems. These robots can be equipped with cameras, sensors, and manipulators to collect data and perform tasks in challenging underwater environments.
  4. Acoustic technology: Underwater acoustic technologies, such as sonar and hydrophones, are used for mapping the seafloor, detecting underwater objects, and studying marine life. These tools are essential for applications like underwater archaeology, fisheries management, and marine mammal research.
  5. Ocean energy technologies: The ocean represents a significant potential source of renewable energy through technologies like wave, tidal, and ocean thermal energy conversion (OTEC). Advances in these areas can help reduce our reliance on fossil fuels and contribute to a sustainable energy future.
  6. Aquaculture technology: The growing demand for seafood has led to the development of innovative aquaculture technologies that can produce fish and shellfish in a sustainable and environmentally friendly manner. These include recirculating aquaculture systems (RAS), offshore fish farming, and integrated multi-trophic aquaculture (IMTA).
  7. Marine pollution mitigation: Technologies aimed at reducing and managing marine pollution include oil spill response equipment, such as skimmers and booms, as well as innovative solutions for addressing plastic pollution, like the Ocean Cleanup project.
  8. Marine communication and navigation: Advances in marine communication and navigation technologies, such as global positioning systems (GPS), satellite-based communication systems, and Automatic Identification System (AIS), have improved safety and efficiency in maritime operations.
  9. Marine geospatial technology: Geographic information systems (GIS), seafloor mapping, and 3D modeling technologies are used to analyze and visualize oceanographic data, supporting applications like habitat mapping, coastal zone management, and marine spatial planning.
