ResumenImportant constraints in sampling repeatability at statistically relevant frequencies are still limiting the progress of marine ecology. Within the framework of novel cabled observatory science, it is now possible to study and monitor the fauna of geologically different ecosystems at any depth of the continental margin, including the abyssal plains, at sampling frequencies and over temporal durations never attained before (i.e. from seconds to decades). New multiparametric platforms endowed with video cameras that are being progressively installed in different oceans, can be used not only for a broad faunal characterization, but also to quantify the massive three-dimensional displacements of marine populations in response to cyclic oceanographic, chemical, and geologic fluctuations (also measured in a multiparametric fashion). Here, we will review how time-lapse image/footage acquisition and automated video-imaging protocols for animal classification and counting could be implemented to transform video-cameras into one of the first intelligent marine sensors for the remote, autonomous and continuous monitoring of communities in relation to their diel (i.e. inertial, internal-tidal or day-night), seasonal, and inter-annual cycles of functioning. We will also discuss the possibility to study the responses of benthic species to other and more stochastic habitat changes (e.g. those linked to the meteorology), through the measurement of modifications in water column properties by observatory vertical expansions. Studies of this kind may allow an efficient modelling of marine community modifications in spite of global change scenarios, based on alterations of the benthopelagic coupling equilibrium
