The oceans are a fundamental source for climate balance, sustainability of resources and life on Earth, therefore society has a strong and pressing interest in maintaining and, where possible, restoring the health of the marine ecosystems. Effective, integrated ocean observation is key to suggesting actions to reduce anthropogenic impact from coastal to deep-sea environments and address the main challenges of the 21st century, which are summarized in the UN Sustainable Development Goals and Blue Growth strategies. The European Multidisciplinary Seafloor and water column Observatory (EMSO), is a European Research Infrastructure Consortium (ERIC), with the aim of providing long-term observations via fixed-point ocean observatories in key environmental locations across European seas from the Arctic to the Black Sea. These may be supported by ship-based observations and autonomous systems such as gliders. In this paper, we present the EMSO Generic Instrument Module (EGIM), a deployment ready multi-sensor instrumentation module, designed to measure physical, biogeochemical, biological and ecosystem variables consistently, in a range of marine environments, over long periods of time. Here, we describe the system, features, configuration, operation and data management. We demonstrate, through a series of coastal and oceanic pilot experiments that the EGIM is a valuable standard ocean observation module, which can significantly improve the capacity of existing ocean observatories and provides the basis for new observatories. The diverse examples of use included the monitoring of fish activity response upon oceanographic variability, hydrothermal vent fluids and particle dispersion, passive acoustic monitoring of marine mammals and time series of environmental variation in the water column. With the EGIM available to all the EMSO Regional Facilities, EMSO will be reaching a milestone in standardization and interoperability, marking a key capability advancement in addressing issues of sustainability in resource and habitat management of the oceans.

“…Underwater camera stabilized platform (UCSP) has a wide range of application values, such as the stable tracking and shooting of underwater creatures through cameras installed on the UCSP [2], [3]. Besides, it can be applied to video surveillance of marine ecological protection areas, and the camera attitude can be adjusted through the UCSP to achieve the goal of stable shooting in a specific direction and area [4]. In order to track the image of the target stably, the camera device needs to adjust the shooting angle along with the movement of the target.…”

System Modeling and Motion Control of a Cable-Driven Parallel Platform for Underwater Camera Stabilization

Underwater camera platform's low image stabilization accuracy and poor waterproofness seriously restrict the quality of photos. In order to better cope with underwater camera work, this paper proposes a cable-driven underwater camera stabilized platform. It is a mobile platform driven in parallel by four flexible cables. To improve image stabilization accuracy and anti-interference performance, the system's dynamic model is established in a non-inertial reference frame. And the random water wave interference is modeled. Moreover, a novel double-loop integral-type global fast terminal sliding mode control strategy is designed. Lyapunov stability theory is used to analyze the stability of the strategy. Finally, by comparing with the existing global fast terminal sliding mode controller and traditional sliding mode controller, the designed controller is simulated and verified. The results show that the proposed control strategy not only has the advantages of fast response and robustness, but also has the characteristics of rapid convergence in a finite time and high accuracy. This method can provide a valuable reference for the development of underwater camera stabilized platforms.INDEX TERMS Cable-driven parallel robot, dynamic model, global fast terminal sliding mode control, underwater stabilized platform.

“…Animal presence, including taxonomic groups such as crustaceans, fish and marine mammals, can also be linked to concurrent fluctuations of environmental variables, recorded by the subsea observatory's oceanographic and geochemical sensors installed alongside cameras (Aguzzi et al, 2015;Del-Rio et al, 2020). Some of the main limitations to the use of video data is that taxonomic resolution to the species level may not be always possible and the quality of image depends on external factors such as water turbidity ( Aguzzi et al, 2020a;Marini et al, 2018). Such limitations can be overcome by improving data acquisition technologies but also by adopting a multidisciplinary approach.…”
