Special Issue Information

Dear Colleagues,

Marine environments are critical to the planet's health and human well-being, yet their vastness and complexity present unique challenges for monitoring and management. Advanced sensor technologies have become indispensable tools for observing and understanding marine ecosystems, detecting environmental changes, and supporting sustainable ocean development.

This Special Issue, entitled "Applications of Sensors in Marine Observation", aims to explore innovative developments and applications of sensors in the marine domain. We seek to highlight how these technologies are being used to monitor oceanographic parameters, assess marine biodiversity, support sustainable resource management, and address emerging challenges in marine science and engineering.

We invite submissions of original research papers, review articles, and brief communications that showcase advancements in sensor design, novel methodologies for data acquisition and analysis, and applications of sensors in diverse marine environments. Topics of interest for this Special Issue include, but are not limited to, the following:

  • Development of innovative sensors for oceanographic measurements.
  • Integration of sensor technologies into autonomous underwater vehicles (AUVs), remotely operated vehicles (ROVs), and other marine platforms.
  • Real-time monitoring solutions for coastal, oceanic, and deep sea environments.
  • Case studies demonstrating the use of sensors for marine resource management and environmental monitoring.
  • Challenges and opportunities in deploying sensors in extreme marine conditions.

We look forward to receiving your contributions that will advance our understanding and sustainable management of the marine environment through sensor technologies.

The need for real-time and scalable oceanographic monitoring has become crucial for coastal management, marine traffic control and environmental sustainability. This study investigates the integration of sensor technology into marine cables to enable real-time monitoring, focusing on tidal cycles and wave characteristics. A 2000 m cable demonstrator was deployed off the coast of Portugal, featuring three active repeater nodes equipped with pressure sensors at varying depths. The goal was to estimate hourly wave periods using fast Fourier transform and calculate significant wave height via a custom peak detection algorithm. The results showed strong coherence with tidal depth variations, with wave period estimates closely aligning with forecasts. The wave height estimations exhibited a clear relationship with tidal cycles, which demonstrates the system’s sensitivity to coastal hydrodynamics, a factor that numerical models designed for open waters often fail to capture. The study also highlights challenges in deep-water monitoring, such as signal attenuation and the need for high sampling rates. Overall, this research emphasises the scalability of sensor-integrated smart marine cables, offering a transformative opportunity to expand oceanographic monitoring capabilities. The findings open the door for future real-time ocean monitoring systems that can deliver valuable insights for coastal management, environmental monitoring and scientific research. Full article
