In this UNESCO video on YouTube you can hear the voice of Vladimir Ryabinin, Former Executive Secretary of UNESCO's Intergovernmental Oceanographic Commission, link.

One way we can learn more about the deep sea environment is by physically going down there with a submarine, and one of the most famous ones is DSV Alvin. Watch this short trailer: link, or the longer video: link, and learn more about this Alvin and it's discoveries in these stunning videos of ChangingSeasTV (submerge - discover - engage).
Fossils activity
Fossils activity
Seasheels and other marine fossils are often found above water and sometimes even on high mountains. How is this possibile?
First discuss what you think it happening, then do this experiment:
Materials:
-shells (or other objects that can rappresent shells)
-sand or dirt, if possibile different colours
-container with water
Method:
1) put water in container and line the bottom with some shells
2) show sedimentation, material brought by erosion that covers the shells
3) repeat several times to show different layers, one can even be a dark material to rappresent a volcano eruption
4) push the container up on one end to show plate tectonics, causing the container to lift up on one side, creating a small mountain
5) dig a bit and see if you can find the fossils
Summary: We've learned about the Second Principal of Ocean Literacy, that the Ocean and life in the Ocean shape the features on Earth.
Q: What did you discover? How did it make you feel? Write in your Ocean Journal and do a beautiful drawing!
On the next pages of the book you'll learn more about Principle Two and how our Earth is shaped by the Ocean:

The second principal of Ocean Literacy can also be applied to the Mediterranean Sea, in this case we can say:
The Mediterranean Sea, xxxx

The image at the top of the page in the header is of a natural saltwater pool called "Piscina di Venere" found at the Cape of Milazzo in Sicily. These rocks have been eroded by waves and wind. However, what's even more interesting is that these rocks were made by life in the Ocean millions of years ago. In fact, they were once at the bottom of the seafloor and are lifting up due to tectonic processes.
