Decades of technical development in electronics, telecommunication, optics and acoustics measuring techniques have opened new possibilities for multi-parameter monitoring of the marine environment. This conference paper will give examples on how fixed multi-parameter platforms are used in a wide variety of applications ranging from shallow coastal on-line observatories down to measuring in the deepest...
Self-contained, moored echo sounders are a means of monitoring the behavior of populations of zooplankton and small fish over extended periods of time. Such instruments, either moored at or near the seafloor looking upward, or mounted on a surface buoy looking downward, record profiles of acoustic backscatter as a time series, and thus can provide insights into the long-term behavior and distribution...
