Abstract
The astronomical movement of the Earth generales geophysical cycles in the form of daily and seasonal changes in the light intensity and length oí the photoperiod in all photlc and disphotic zones, plus the marked hydrodynamic patterning of tides. These temporally predictable changes impose a strict synchronization with the vital processes of the species through adaptation by natural selectíon: rhythms at different levels of complexity, from genetic aspects to behavior. From the studies carried out with the objective of exploring blodiverslty and monitoring the ecosystem functíoning, a great variability is observed in the sampling of marine species. This variability can be produced by the rhythmic movements of the populations synchnousely with the day-night, seasonal, and tidal cycles. Monitoring biodiversity and the environmental drivers controlling those rhythms at different spatiotemporal scales is a key issue in a context of increasing anthropogenic impact across the breadth of continental margins. In this complex scenario, and to comply with the monitoring of biological indicators set by the European Community Marine Strategy Framework Directive (MSFD), the project propases the development and the coupling of new fixed and mobile multi-parameter platfonns, developing at the same time new methodologies for sampling the composition of communities and relative abundance of species in relation to species rhythmic act.ivity and its environmental control. The use of seabed cabled observatories equipped with video cameras will allow real-time study of behavioral rhythms, and consequently their effects on the dynamics of a community, with great temporal resolution and for long periods of time. Fluctuations in counted individuals using video­images can be used as an indicator oí a population's rhythms, to be related with the surrounding habitat conditioning, in terms of cause­and-effect principies via a concomitan! multiparametric data aquistion. Different oceanographic, chemical and geological parameters will then also be used aside cameras. In order to increase spatial coverage and allow for strategic and adaptive changes In monitoring, autonomous underwater vehicles (AUVs) and benthic robots (crawlers) will be used, which will work in both spatial (near-area) and time­coordinated fashion vía platform communication. This multi-parametric monitoring is a challenge to be overcome in arder to have standardized protocols for the acquisition and automation of data processing regarding species composition (i.e. richness), relalive abundances (i.e. evenness) and food web structure. Although this proposal is aimed at environmental monitoring, in the future it could be extended and serve as a reference íor other more industrial sectors. The collection of biological and environmental data with the mínimum human intervention is also relevan! in a wide range of marine activities of strateglc interest to the offshore economy in !he European community related to the measurement of impacts in more impacted areas such as extractive oíl, gas or míning practices and emerging actívities such as the deployment of as renewable energies.
