With the ocean providing so many goods and services to human population, if we are to sustainably manage its resources, it is important for everyone, not just those living on the coast, to value marine ecosystems. Luckily recent developments of online immersive technologies can be employed to provide easy access to the ocean, from its coasts to its depths. Ocean School is an online platform dedicated to teaching students about the urgent challenges associated with understanding and protecting the global ocean. It also provides educators with material to incorporate ocean literacy into their regular curriculum.
