context_page_description: The ecoSCOPE is an optical sensor system, deployed from a small remotely operated vehicle or fibre optic cable, to investigate behavior and microdistribution of small organisms in the ocean.
context_section_description: The ecoSCOPE is a product of the new initiative of "Ocean Online Biosensors": a synthesis of IT-sensoric and the sensing capability of ocean organisms.
  Depicted in the image on the right is the central unit. On all four corners are small entrances, through which water from different sources enters (in this case, rivers and creeks in New Jersey).  It flows through a small labyrinth and mixes in the central chamber. It exits through a small tube in the middle. The glasseels migrate through this small tube heading into the current. In the middle is the entrance for the eels. They test the different water qualities and migrate toward the corner, where they exit.
  It is the opinion of many scientists that eels have developed the finest nose on the planet. They can sense concentrations of one part in 19 trillion. This is the same concentration as one glass of alcohol in the waters of all America's Great Lakes. For the eels the sensory impressions are probably as diverse as the colors visible for us.
  The system is submerged, and a digital camera observes the exits. The dynIMAGE software monitors the frequency of decisions per exit. Many thousand of glasseels pass through the system on a single day. The three exits in the left lower corner carry water from polluted sources (one is a drinking water reservoir).
  EcoSCOPE systems have already been tracking water pollution and its effect on fish and plankton behavior in Europe and the United States). For the future it is anticipated to deploy ecoSCOPEs continuously online, within the project LEO Projekt off New York City, visible for the public. Tests have also been performed with different qualities of drinking water and with solutions of runoff juice from different samples of fish.
