Rudy the Rock

Hey, I’m Rudy… The Rock! I am willing to tell you about my first crazy contact with what is called “human” scientists (quite different to my usual rocky neighbors). The last million years, it was calm and silent since my eruption birth at Conical Seamount. We lived in a peaceful stony community at 1400m below […]

Building Bridges

How is one giant research vessel managed? Well, like any ship of this size, you will find the answer on what’s called the bridge. No worries, we are not trying to connect different ships between each other. That is just the main working station from which the ship is navigated. A little bit like the […]

This mooring measured continuously temperature and salinity in the central Labrador Sea since the early 1990s. More recently, oxygen sensors have been added to the uppermost part of the mooring. Measuring oxygen in the central Labrador Sea is quite […]

The uCTD is a good compromise between research time, efforts, and the dataset we get from it. Indeed, the ability to get […]

Eddy Survey

By Anne-Sophie Fortin August 24-26, 2022 If the marine life would have weather forecasts, they would have eddies maps. Eddies are circular currents of tens to hundreds of kilometers in diameter and a lifetime of about a month. They can be seen on satellite imagery as minimums and maximums of sea surface heights and sea […]
