Scroll to see the ocean’s deepest depths is an interactive infographic from The BBC. Scroll down the infographic and it not only shows you information about what is happening at that depth of the ocean, it also provides videos and images. It’s similar to “Our Amazing Planet: Top To Bottom,”, but there’s no interactivity in that infographic (that one also covers above the ocean).
The BBC resource is part of a very extensive multimedia feature on the ocean.
