Cabled observatories are seabed

oceanographic Oceanography (), also known as oceanology and ocean science, is the scientific study of the oceans. It is an Earth science, which covers a wide range of topics, including ecosystem dynamics; ocean currents, waves, and geophysical fluid dynamics ...

. By removing the limitations of undersea power sources and sonar or RF communications, cabled observatories allow persistent study of underwater phenomena.Woods Hole Oceanographic Institute page

/ref> multiple or branching cables may then provide data in 2D or 3D. The extent of coverage is limited by the high cost of laying dedicated undersea cable. Initial experiments used abandoned communications cables; efforts are in progress to extend observations at lower cost by accessing more such cables. Despite their advantages, cabled observatories can (and do) relay compromised data to scientists, particularly when located in remote parts of the ocean. Factors such as instrumental malfunction and biofouling are often responsible for this. Systematic improvements, to lessen the impacts of such factors, are currently being studied by groups such as
