The Lofoten-Vesterålen Ocean observatory; Understanding behavioural response of benthic organisms from long-term multi-sensor data
The Lofoten-Versterålen (LoVe) Ocean Observatory is a cabled observatory on the Norwegian continental shelf providing long-term environmental data, including time-lapse imagery of a cold-water coral reef, from a multisensory stationary platform. The high temporal data resolution (frequency and durat...
