First deliveries of ecoSUBm5-Power+ AUV with ecoCAM
ecoCAM is a brand new 4k video and still image camera developed by the ecoSUB team, fully integrated into the ecoSUBm5-Power+ AUV system. The camera system has been designed to provide extremely high-quality video and still images, whilst being an ideal solution for machine learning applications. A 1.1” Sony IMX267 global shutter CMOS sensor, coupled with a Computar fixed 8mm lens provides high resolution, high frame rates and noise free image reproduction (8.85 MPix (4096 x 2160 px) at 33.0 fps). The camera is an underwater first, running with Subsea USBC data transfer, to provide excellent data speed for video encoding on a Jetson Orin Nano computer.
Both new users from the US and Germany intend to use the ecoCAM for machine vision applications, benefitting from the power of the Nvidia Jetson backseat computer, enabling edge computing. In one case the camera feed is being used with a navigation algorithm to pilot the vehicle into a docking station.
The ecoCAM module is a compact unit, rated to 2,500m, suitable for ecoSUBm-series AUV platforms, and is mounted in a custom nose cone that allows the camera to be orientated from forward looking to downward looking for seabed imaging. Subsea lighting packages can be provided for low/zero light applications. Onboard our ecoSUBm5-Power+ AUV platform, the ecoCAM can be coupled with side scan sonar, DVL and acoustic modem for underwater coms and USBL, if required.
Use case: SPARUS II AUV for critical underwater infrastructure inspection
99% of the communications occurring in the world today happen through underwater fiber optic networks. There are more than 420 submarine lines in the world, totalling 1.3 million kilometers which allow us to communicate and operate in the way we do as a society. These infrastructures are equally important today as oil and gas pipelines, since the volume of financial transactions, very relevant to the system, run through these underwater cables.
Underwater environments are hazardous and especially difficult to monitor for two main reasons: firstly, the locations themselves may be areas of difficult access either for their depth, the existing currents, or even the movements of the seafloor and, secondly, the technologies that are commonly available in the surface, like GPS or WiFi will not work. So, there is a clear vulnerability for the security of these infrastructures.
On average, there are over a hundred breaks of submarine cables every year, caused in general by the fishing boats that pull the anchors. But, being identified as critical infrastructure, they are also a target for potential sabotage. The first attacks registered date back in 2017. Although they remain unknown to the general public, they are no less worrying and prove the capacity of external powers to separate Europe from the rest of the world.
Keeping this context in mind and in the framework of “Robotic Experimentation and Prototyping using Maritime Uncrewed Systems” (REPMUS) exercise, multiple technologies for automatic underwater cable detection and inspection were tested in a simulated complex scenario. Led by NATO, the event takes place annually in the Lisbon coastal area hosted by the Portuguese Navy.
IQUA robotics participated in REPMUS 2023 exercise, invited by the Spanish Navy to prove the capabilities of its vehicle SPARUS II AUV for the described mission. The goal of the mission was to, in a completely autonomous way, locate the cable and inspect it from nearby to be able to identify potential threats to it.
One of the characteristics of the SPARUS II AUV is its possibilities to be configured according to the mission needs, in this case, the vehicle was equipped with an optic camera system developed by IQUA and a commercial forward looking sonar.
The IQUA Robotics strategy for addressing the assigned task consisted of the following steps:
- Deploying the AUV in proximity to the supposed cable location.
- Executing a predefined autonomous mission within the area, while employing an automated algorithm to continuously analyze incoming forward-looking sonar data to detect the cable presence.
- Without human intervention and without requiring resurfacing, the AUV automatically plans a trajectory connecting all potential cable locations observed in the sonar images.
- The AUV then follows the planned trajectory close to the seafloor, enabling the camera system to capture images of the cable along its route.
- Returning to the surface with the collected data.
Throughout the mission, real-time monitoring was conducted from the surface through the IQUAview user interface, which visualized data transmitted by the AUV via an acoustic modem. The collected data allowed the creation of acoustic maps and visual reconstructions along the cable.
The image below shows a mosaic of approximately 150m long x 2.5m wide where one suspicious element is clearly identified (60x20cm) and can be seen with high resolution for its interpretation. The capability of finding such objects closeby the cables without human intervention can be key to the future of the security of critical underwater infrastructures.

Cyber-Taxonomy: Set to transform our knowledge of life on Earth with Ocean Census
Groundbreaking initiative, coordinated by The Nippon Foundation and Nekton, harnesses major technology advances to accelerate the discovery and documentation of ocean life, tackling the significant knowledge gap in marine biodiversity.
A landmark new approach to the discovery of life - cyber-taxonomy - has been revealed in Frontiers of Marine Science. Co-designed by dozens of international experts, the new approach creates digital twins of each species and provides the revolutionary potential that is underpinning Ocean Census, a large-scale strategic science mission, designed to significantly accelerate the discovery and documentation of marine species.
The initiative tackles the pressing knowledge gap surrounding the diversity and distribution of marine life by deploying an innovative cyber-taxonomy approach, merging traditional taxonomy methods with cutting-edge technologies such as DNA sequencing, high-resolution digital imaging and machine learning.
The ocean, the largest ecosystem on Earth, harbours an unrivalled area of wilderness, making the preservation of its biodiversity crucial for ecological equilibrium and human well-being. Understanding the myriad forms of marine life is imperative for realising its societal benefits and mitigating human impacts to sustain healthy marine ecosystems.
“Life has evolved in our ocean for three times as long as life on land and holds the clues to four billion years of our evolutionary heritage. Cyber-taxonomy will enable Ocean Census to discover, sequence and decode the DNA of ocean life, increasing the speed and scale of the discovery exponentially.”
Yohei Sasakawa, Chair of The Nippon Foundation.
Although it’s estimated that between 1-2 million species inhabit our ocean, around 75% to 90% remain undescribed. The longstanding void in the knowledge and observation of marine species is concerning, with potential unrecorded extinctions and declines aggravating the prevailing biodiversity crisis. It is very difficult to protect what is not yet known. It currently takes one to two years to several decades to describe a species from its initial collection, necessitating an expedited approach to marine discovery.
Launched this April by The Nippon Foundation of Japan and UK-based marine research charity Nekton, Ocean Census harnesses the latest DNA sequencing digital imaging technologies and machine learning with conventional taxonomy, optimising the species identification and description process. Through these approaches, a digital twin, or ‘Digital Life Form’ of each specimen is created.
Taxonomists then draw on the data to determine if the species are new to science. Ocean Census aims to utilise cyber-taxonomy with an ambitious target of 100,000 new species discovered within the decade.
Through the digitization of specimen collection data and the creation of a cyber-biodiversity system for data distribution, the initiative grants far greater and more equitable access to biodiversity knowledge, propelling species discovery to unprecedented levels and galvanising conservation efforts.
"Ocean Census is not merely about discovering the unknown but reshaping the way we understand marine biodiversity. The integration of advanced technologies with traditional taxonomic studies is pivotal. It rejuvenates our pursuit of knowledge in marine biology, addressing the urgent need for detailed information on diverse marine species to counter the prevailing biodiversity crisis."
Prof. Dr. Alex Rogers, Science Director at Ocean Census and leading co-author of the paper.
Cyber-taxonomy emerges as a distinctive, transformative methodology, intertwining technology and taxonomy to drive humankind closer to Ocean Census’ ambitious scientific, exploration and conservation goals. This approach empowers scientists to address critical questions in marine biology and conservation more effectively, fostering an enriched understanding of global patterns and processes in marine ecosystems.
"The cyber-taxonomy approach is at the heart of Ocean Census. It is not only innovative but essential in revolutionising our approach to discovering and studying marine life. Through this, we can disseminate knowledge at an unprecedented scale, allowing more discoveries to be made rapidly.”
Dr. Tim O’Hara, co-author and Senior Curator at Museums Victoria, Australia.
Ocean Census is constructing a global network of scientists and Biodiversity Centres, fostering collaboration to enhance ocean life discovery efforts worldwide, including in low- and middle-income countries. By ensuring equitable involvement and knowledge sharing, discoveries made under this initiative are universally accessible, enriching global biodiversity comprehension.
"This mission is a testament to the power of global collaboration. By bringing together minds and resources from around the world, we are ensuring that the discoveries made are not just advancements in science but contributions to global knowledge, accessible to all."
Dr. Punyasloke Bhadury, co-author and professor at the Indian Institute of Science Education and Research Kolkata.
The groundbreaking paper, published on 27 September, does not merely shed light on the immense possibilities of discovering unknown marine species but also emphasises the critical necessity of such discoveries in the face of the escalating global biodiversity crisis. The preservation of knowledge, including genomic data of species on the brink of extinction, is integral to sustaining and revitalising the rich tapestry of marine life.
“This paper accentuates the pivotal role of technology-infused taxonomy in expediting the unravelling of oceanic mysteries, ultimately contributing to the conservation and sustainable management of our oceans' invaluable biodiversity. The taxonomic achievements with an inclusive initiative with the countries without natural history museums will raise the basis of natural science globally.”
Dr. Hiromi K Watanabe, co-author and malacologist at the Institute for Extra-Cutting-Edge Science and Technology Avant-Garde Research (X-Star), Japan Agency for Marine-Earth Science and Technology (JAMSTEC).
