Coriolis Effect ✍️

It explains why objects moving across a rotating world seem to curve from their straight path, even when no visible force pushes them sideways. Imagine throwing a ball straight across a spinning merry-go-round. To someone standing still outside, the ball travels in a straight line. But to someone riding the spinning platform, the ball appears to bend away from its path.

The same thing happens on Earth because our planet is constantly rotating beneath everything that moves. Air currents, ocean flows, and even long-range projectiles travel over a surface that is turning while they move. This creates the illusion of a sideways force, known as the Coriolis effect.

In the Northern Hemisphere, moving objects appear to bend to the right, while in the Southern Hemisphere they bend to the left. The effect grows stronger over larger distances and faster motions, but becomes almost unnoticeable in small, everyday movements.

Scientists use this effect to understand the spinning of hurricanes, the paths of trade winds, and the circulation of oceans. It reveals that motion is not always as simple as it seems when the ground beneath us is constantly in motion itself.

Arctic Carbon Conveyor Belt Discovered https://www.awi.de/en/about-us/service/press/single-view/arktisches-kohlenstoff-foerderband-entdeckt.html

#CarbonDioxide sink in the #ArcticOcean from cross-shelf transport of dense #BarentsSea water https://www.nature.com/articles/s41561-022-01069-z

A previously unknown transport route uses the biological #CarbonPump and #OceanCurrents to absorb atmospheric #CO2 on the scale of Iceland’s total annual #emissions. The outflow manifests in seasonal pulses, since in the #Arctic, the absorption of CO2 by #phytoplankton only takes place in summer.
