"[W]ere past the point now where we say you have to go to sea to be an oceanographer, because its not true, and its actually very important that it isnt true."

"My favorite element is . Thats mainly because of this organism... a ... a tiny... organism that lives in the surface of the ocean..."

"[A]ll of these platelets, this really intricate structure... is made of so calcium is incorporated into this structure..."

"This organism lives, and it dies, and quite often when it dies, the broken fragments... drift down... and... can build up... on the floor of the ocean, and over geological time these beautiful little platelets of calcium carbonate become squashed into rocks of calcium... [A]s techtonic plates move around and seas come and go, those rocks can get lifted up and so this... is what the White Cliffs of Dover are made of..."

"So after the calcium has been part of the cliffs it can crumble down... It goes back into the ocean and this cycle starts all over again."

"And... it changes the ecosystem because the penguins can then survive in conditions they would not otherwise be able to survive in."
