Oceanic Research: January 2022


The Labrador Sea between Canada and Greenland is often referred to as a 'lung of the deep ocean' because it is one of only a handful of locations worldwide where oxygen from the atmosphere can enter the deepest layers of the ocean.

By drilling deep down into sediments on the ocean floor researchers can travel back in time. A research team led from Uppsala University now presents new clues as to when and why a period often referred to as the 'biogenic bloom' came to an abrupt end. Changes in the shape of the Earth's orbit around the Sun may have played a part in the dramatic change.
