Query: New high-tech flexible networks for the monitoring of deep-sea
  ecosystems   Increasing interest in the acquisition of biotic and abiotic resources from
within the deep sea (e.g. fisheries, oil-gas extraction, and mining) urgently
imposes the development of novel monitoring technologies, beyond the
traditional vessel-assisted, time-consuming, high-cost sampling surveys. The
implementation of permanent networks of seabed and water-column cabled (fixed)
and docked mobile platforms is presently enforced, to cooperatively measure
biological features and environmental (physico-chemical) parameters. Video and
acoustic (i.e. optoacoustic) imaging are becoming central approaches for
studying benthic fauna (e.g. quantifying species presence, behaviour, and
trophic interactions) in a remote, continuous, and prolonged fashion. Imaging
is also being complemented by in situ environmental-DNA sequencing
technologies, allowing the traceability of a wide range of organisms (including
prokaryotes) beyond the reach of optoacoustic tools. Here, we describe the
different fixed and mobile platforms of those benthic and pelagic monitoring
networks, proposing at the same time an innovative roadmap for the automated
computing of hierarchical ecological information of deep-sea ecosystems (i.e.
from single species abundance and life traits, to community composition, and
overall biodiversity)
