The scientific and technological revolution in Internet of Things is set off in oceanography. Humans have always observed the ocean outside the ocean to study the ocean. In recent years, it changes have been made into the interior of the ocean and the laboratories have been built on the sea floor. Approximately 71% of the Earth’s surface is covered by water. Ocean of things is expected to be important for disaster prevention, ocean resource exploration, and underwater environmental monitoring. Different from traditional wireless sensor networks, ocean of things has its own unique features, such as low reliability and narrow bandwidth. These features may be great challenges for ocean of things. Furthermore, the integration of artificial intelligence and ocean of things has become a topic of increasing interests for oceanology research fields. Cognitive ocean of things (COT) will become the mainstream of future ocean science and engineering development. In this paper, we provide the definition of COT, and the main contributions of this paper are (1) we review the ocean observing networks all the world; (2) we propose the COT architecture and describe the details of it; (3) important and useful applications are discussed; (4) we point out the future trends of COT researches.
