Video from the drilling ship Joides Resolution (National Science Foundation) show off what happens to produce things that get captioned Thin Section Thursday - looking at a tiny slice of a rock under a microscope and spinning the stage around.

Une doctorante de l’UPVD en mission océanographique en Antarctique
Margot Courtillat, doctorante au sein du laboratoire CEFREM de l’UPVD partira pour une expédition scientifique de deux mois en Antarctique du 23 janvier au 20 mars 2019. La jeune chercheuse aura pour mission d’étudier l’évolution du climat dans cette région reculée du monde. Seule française à bord du navire scientifique JOIDES Resolution qui comptera 30 chercheurs du monde entier, 86 techniciens…

Ever wonder what scientists do at sea? Well, here’s a new video from the US deep sea drilling vessel, the Joides Resolution. It’s quite accurate. I’d also recommend it for students and teachers interested in what scientists actually do.
So, we know that it's because of plate tectonics that our oceans are growing and shrinking, we know from cores Drilled into the sea bed that the climate of the Earth changed on a cyclical cycle, we know about past organisms and extinctions, but what about the research vessels that conduct these studies?
The JOIDES Resolution is one such research vessel that participates in the Ocean Drilling Program. With palaeontologists, geologists, geochemists and technicians all aboard the ship on each leg, it's a floating laboratory!

It's a leaf!
One core we brought up one expedition 344 happened to have a leaf exactly at the end. This leaf is millions of years old! Well, actually, it is now a leaf-shaped pattern of carbon compounds.
What are the odds of cutting the core right at this point? What does that imply about the number of leaves present in this sedimentary unit? At the very least, it tells us that these sediments have a significant terriginous influence, despite being fine-grained and pretty far from land when they were deposited.

Biostratigraphy and Paleomagnetism Groups describe what they do. Good explanations, and the graphics are pretty good too!
