How Drones and Underwater Robotics Are Revolutionizing Marine Science
The integration of drones and underwater robotics is redefining the scope and scale of marine research. What once depended on expensive expeditions and limited human access is now being enhanced—and in some cases replaced—by autonomous and remotely operated systems. These technologies are not only improving the quality and reach of scientific data but are also transforming the professional profiles required in the marine sciences sector.
Strategic Value for the Blue Economy
According to the OECD’s Ocean Economy Outlook, the blue economy is projected to reach $3 trillion by 2030. In this context, precision marine data is a strategic asset—not only for science and conservation but also for infrastructure planning, offshore wind development, fisheries management, and climate adaptation.
The ability to deploy cost-effective, low-impact technologies is fast becoming a competitive advantage for both public institutions and private enterprises. Professionals who understand and operate this new generation of tools are shaping the future of ocean sustainability.
Key Advantages Over Traditional Data Collection
● Safety: Risk to divers and crew is significantly reduced when deploying unmanned vehicles in deep or hazardous conditions.
● Extended Range and Duration: Autonomous systems can operate for hours or days in remote regions, gathering continuous high-resolution data.
● Data Quality: Drones and robots are equipped with precision instruments like LiDAR, sonar, CTDs, and HD cameras, offering more accurate measurements than many manual methods.
● Cost Efficiency: These systems reduce the need for large research vessels and extended onboard missions, making research more accessible.
● Environmental Responsibility: Minimally invasive data collection is vital in sensitive ecosystems, helping reduce the footprint of scientific operations.
Applications of Underwater ROVs
Underwater ROVs are increasingly being used in port environments and offshore structures for inspection, structural condition monitoring, and preventive maintenance. In ports, they allow inspection of vessel hulls, docks, pilot buildings, and hard-to-reach areas without having to halt operations. In offshore structures, such as offshore wind farms or floating platforms, they are key for assessing the condition of submerged elements and anticipating potential failures.
Their ease of deployment and ability to operate for extended periods make them an ideal tool for recurring inspections, which is essential in infrastructure exposed to extreme conditions and corrosive environments. Furthermore, since they do not require the presence of divers, operational complexity and human risks are significantly reduced.
A representative case is that of the company EONSEA, which uses ROVs to perform periodic underwater inspections of vessels and port and offshore infrastructure. In addition to the use of ROVs, EONSEA incorporates an artificial intelligence layer that automatically analyzes the images collected during dives. This technology identifies patterns of corrosion, biofouling, or structural damage, generating automatic reports with maintenance recommendations.
Emerging Skillsets and Career Profiles
The shift toward automated marine observation calls for professionals who can operate at the intersection of oceanography, data science, and robotics. Key roles include:
● Marine Robotics Engineers, often working with platforms like BlueROV2 or Saildrone, manage the design, deployment, and maintenance of underwater vehicles.
● Remote Sensing & GIS Analysts, using tools such as QGIS or ArcGIS, extract geospatial insights from drone-captured imagery.
● Environmental Data Scientists, experienced in Python, MATLAB, or R, process complex data streams from multiple sensors and create models to inform climate policy and conservation.
● Field Technicians, trained in operating both aerial and underwater drones, perform real-time missions, troubleshoot hardware, and manage data capture in situ.
Institutions such as the Schmidt Ocean Institute and Woods Hole Oceanographic Institution (WHOI) are increasingly offering training programs and hiring for these hybrid roles. If you prefer to study in Spanish, la Fundación Ingeniero Jorge Juan offers a wide online training opportunities related to marine robotics such as the “Apoyo al Ciclo de Vida de motores y su implementación en la Industria 4.0 mediante el gemelo digital (30-05-2025 - 01-08-2025)”, “Introducción a Python en el Sector Marítimo (30-05-2025 - 18-07-2025)” and “Introducción a la inteligencia artificial y a la minería de datos en el Sector Marítimo (03-06-2025 - 16-09-2025)”.
