"The OceanCube, which is about double the size of an air conditioning radiator, is encased with plastic and is connected to steel-armored fiber optic cables snaking along the ocean floor. The cables transmit real-time data from the OceanCube to a laboratory inside the Okinawa Churaumi Aquarium ... The instruments calculate water motion and observe the underwater environment, creating a three-dimensional map of the current's velocity and the flux of water. As the ocean warms and fresh water from melting ice increases, scientists have yet to fully know how that will affect fish communities and coral reefs." (Quoted from article)
