A hole in the ship?

During Expedition 374, the moonpool was fully opened to lower the subsea camera system to the sea floor. I have always heard about Archimedes’ principle and I know that it explains why heavy ships like the JOIDES Resolution (145 m long and 21 m wide) can float on the water without sinking. But, I didn’t think that it could be compatible with the presence of a hole like the moonpool in the bottom of the...…

Cracked Science: Love In Your Genes

  Can you find love in your genetic code? Is there such a thing as DNA-crossed lovers? Some direct-to-consumer companies, like "Instant Chemistry", want to test the compatibility of your relationship by looking at your genes... but is there clear science on this issue or is this repackaged astrology? My latest video for the McGill Office for Science and Society!

#460 Brake For Menopause

I don't know about you, but when I learned about the female reproductive cycle, I learned that hey, these are the hormone changes that happen. Then in menopause they stop. And you get hot flashes. But it turns out it is a lot more complicated than that. First, we'll speak with cognitive neuroscientist Lauren Drogos about the memory changes that happen during menopause. Then, where does this menopause thing even come from and why don't…

Tracking the age of the core

Does the grey stuff in the bowl look like common mud to you? Maybe for us but definitely not for our paleontologists! This is a very special part of the core, delivered quickly to their lab soon after the core reached the core deck. These sediments were in the core catcher, at the bottom of the core. They are the oldest sediments of each core that we recover and our paleontologists come at each “core...…

037 – Birth Control and Instant Chemistry

  Chris' goodwill to help out a young couple on Valentine's Day backfires, which leads him and Jonathan to talk about contraception. What is the most effective form of birth control, and how come there's no pill... for men? One thing's for certain: McGill students are going to have a lot of unplanned babies if the vox pop is any indication! Also: can science really tell you how compatible you and your lover are?; Britt…

The crucial role of ice shelves

What is an ice shelf? Ice shelves are floating tongues of ice that extend from grounded glaciers on land. The place where the ice sheets touch the ocean floor is called the grounding line. The grounding line is the border between the floating ice shelf and the land-based ice sheet. Ice shelves surround 75% of Antarctica’s coastline and they can be up to 2000 m thick. The Ross Ice Shelf is the largest one, and...…

Celebrating 60 years of Antarctic Scientific Research and 50 years of Scientific Ocean Drilling

Guest post by co-chief scientist Laura De Santis from Instituto Nazionale di Oceanografia e di Geofisica Sperimentale (OGS): This year the Scientific Committee on Antarctic Research (SCAR) and International Ocean Discovery Program (IODP) mark six and five decades, respectively, of successful international scientific achievements. SCAR, with a membership representing the scientific communities of 43 countries, is an international network of thousands of scientists who share a common ambition to carry out Antarctic science for the...…

360 Video: Core on Deck

This is our first in a series of 360 videos. This video shows a core coming on deck on the catwalk. It fades to a microbiologist taking a sample from the core, and then the technicians beginning to take the 1.5 meter sections of the cores into the lab. On the wall opposite the core liner, you can see a micropaleontologist waiting for the core catcher sample to take back to the lab. In the...…
