Special Issue Information

Dear Colleagues,

Autonomous Underwater Vehicles (AUVs) can now provide an unprecedented increase in both resolution and seafloor coverage available for marine research. AUVs can cover large distances at high speeds or maneuver in complex terrain, and their low altitude above the seafloor enables data resolutions orders of magnitudes higher than ship-based sensors have been able to provide. Their ability to automatically map contiguous areas of interest, as well as to explore unknown territory using a range of survey approaches increases the cost-efficiency of ocean science. AUVs are also robust platforms for a variety of imaging sensors, like cameras and echosounders, as well as traditional ocean science gear like CTDs. More recent developments are incorporating novel technologies such as eDNA samplers or artificial intelligence for adaptive mission planning, increasing further the versatility of these platforms.

This Special Issue focuses on two aspects of AUVs. First are applications of these versatile platforms for mapping and monitoring the seafloor. This includes, amongst others, biological, geological, archaeological and infrastructure surveying tasks. The second focus is on the AUV platform itself: its efficient deployment to solve specific mapping or monitoring tasks, its evolving capabilities regarding sensor payload, its expected progress from the automated, (in essence pre-programmed), execution of a task towards true autonomy.

Autonomous underwater vehicles (AUVs) have increasingly played a key role in monitoring the marine environment, studying its physical-chemical parameters for the supervision of endangered species. AUVs now include a power source and an intelligent control system that allows them to autonomously carry out programmed tasks. Their navigation system is much more challenging than that of land-based applications, due to the lack of connected networks in the marine environment. On the other hand, due to the latest developments in neural networks, particularly deep learning (DL), the visual recognition systems can achieve impressive performance. Computer vision (CV) has especially improved the field of object detection. Although all the developed DL algorithms can be deployed in the cloud, the present cloud computing system is unable to manage and analyze the massive amount of computing power and data. Edge intelligence is expected to replace DL computation in the cloud, providing various distributed, low-latency and reliable intelligent services. This paper proposes an AUV model system designed to overcome latency challenges in the supervision and tracking process by using edge computing in an IoT gateway. The IoT gateway is used to connect the AUV control system to the internet. The proposed model successfully carried out a long-term monitoring mission in a predefined area of shallow water in the Mar Menor (Spain) to track the underwater Pinna nobilis (fan mussel) species. The obtained results clearly justify the proposed system’s design and highlight the cloud and edge architecture performances. They also indicate the need for a hybrid cloud/edge architecture to ensure a real-time control loop for better latency and accuracy to meet the system’s requirements. Full article

The methods of data collection, processing, and assessment of the quality of the results of a survey conducted at the Southern Ionian Sea off the Messinian Peninsula, Greece are presented. Data were collected by the GEBCO-Nippon Foundation Alumni Team, competing in the Shell Ocean Discovery XPRIZE, during the Final Round of the competition. Data acquisition was conducted by the means of unmanned vehicles only. The mapping system was composed of a single deep water AUV (Autonomous Underwater Vehicle), equipped with a high-resolution synthetic aperture sonar HISAS 1032 and multibeam echosounder EM 2040, partnered with a USV (Unmanned Surface Vessel). The USV provided positioning data as well as mapping the seafloor from the surface, using a hull-mounted multibeam echosounder EM 304. Bathymetry and imagery data were collected for 24 h and then processed for 48 h, with the extensive use of cloud technology and automatic data processing. Finally, all datasets were combined to generate a 5-m resolution bathymetric surface, as an example of the deep-water mapping capabilities of the unmanned vehicles’ cooperation and their sensors’ integration.
