Expert Geologist Talks to us about Mapping the Ocean Floor

Today Rosa's Dad, Richard, came to talk to us. He is a geologist who has worked with scientists when they go out and explore the deep sea. His job was to map the oceans. They used ships with eco sounders to measure and map the oceans.They now map them in 3D.He showed us what the bottom of ocean looked like. It is very bumpy and just like the land surface above water! He showed us photos of fish that have adapted to survive in extreme conditions like the deep sea. Ocean explorers use special boat, Tangaroa,that has a lot of expensive equipment on board to take them to places like Antartica. They also use smaller boats to get into smaller places. They need to wear special clothing to protect them. He said there are a lot of things still to discover about the ocean.
