	abstract = {Cabled observatories are marine infrastructures equipped with biogeochemical and oceanographic sensors as well as High-Definition video and audio equipment, hence providing unprecedented opportunities to study marine biotic and abiotic components. Additionally, non-invasive monitoring approaches such as environmental DNA (eDNA) metabarcoding have further enhanced the ability to characterize marine life. Although the use of non-invasive tools beholds great potential for the sustainable monitoring of biodiversity and declining natural resources, such techniques are rarely used in parallel and understanding their limitations is challenging. Thus, this study combined Underwater Video (UV) with eDNA metabarcoding data to produce marine fish community profiles over a 2 months period in situ at a cabled observatory in the northeast Atlantic (SmartBay Ireland). By combining both approaches, an increased number of fish could be identified to the species level (total of 22 species), including ecologically and economically important species such as Atlantic cod, whiting, mackerel and monkfish. The eDNA approach alone successfully identified a higher number of species (59\%) compared to the UV approach (18\%), whereby 23\% of species were detected by both methods. The parallel implementation of point collection eDNA and time series UV data not only confirmed expectations of the corroborative effect of using multiple disciplines in fish community composition, but also enabled the assessment of limitations intrinsic to each technique including the identification of false-negative detections in one sampling technology relative to the other. This work showcased the usefulness of cabled observatories as key platforms for in situ empirical assessment of both challenges and prospects of novel technologies in aid to future monitoring of marine life.

	abstract = {As part of a recent Japanese governmental project, the government has planned and begun a program to develop a seafloor cabled observatory that facilitates the long-term monitoring of hydrothermal vents and the ecological changes surrounding them. Because commercial cables are typically laid to avoid rough terrain and hydrothermal fields, there is no established method to assess system damage risk for a cabled observatory installed on a hydrothermal field. In this article, we propose a probabilistic cable damage risk assessment method for a seafloor cabled observatory installed on a hydrothermal field. The core concept of our method is the use of probability functions to estimate the system damage risk for the system of a seafloor cabled observatory laid on a defined route. The considered damage factors are potential heat damage risks to the cabled system and damage risks caused by frequent contact between the cable and seafloor. The product of each risk probability represents the total survivability of the system on the route. The proposed method was applied to the Oomuro-hole hydrothermal field on the active submarine Oomuro-dashi volcano, where remotely operated vehicle (ROV) surveys have been performed. The discovered risk factors are organized into a geographic database, and risk value fields are generated. We planned and evaluated several candidate routes that connect a target site for observation to the cabled system terminal unit. Finally, the proposed method derives quantitative system survivability values for the candidate routes and facilitates planning of the layout for a seafloor cabled observatory installed on a hydrothermal field.},
