Want to learn more about the Ocean? Esri has a cool platform that lets people share what they know through a combination of pictures, maps, texts and animations. The resulting presentations (called "Story maps") are a bit like Powerpoint presentations but not quite. Among other things you can learn more about whales, the Great Barrier Reef and Gulf Spill Restoration Projects.
While viewing a presentation, scrolling downward will make it load more content. If you want to go back to a previous part of the presentation, just scroll upwards.

The Story Maps can be found here:
