Ocean's Giants: Waves Shaping Climate
March 2023
University of Cambridge

Introduction
Dive into the depths of the Atlantic with researchers from the University of Cambridge and friends, as they uncover the ocean's secret powerhouses - giant underwater waves! These aren't your average beach waves; some tower up to 500 meters high and play a massive role in the ocean's climate control, affecting how it absorbs carbon and heat. Think of the ocean as a giant layer cake, with these waves mixing things up, ensuring the deep blue can store our planet's excesses. This intriguing study, published in AGU Advances, might just change how we model our climate. Ready to ride the wave of discovery?

Diving Deep into Ocean Secrets
Imagine the ocean as a bustling city, with its own highways of currents and waves taller than skyscrapers, hidden beneath its surface. This hidden world plays a critical role in our planet’s climate by storing heat and carbon emitted by human activities. The ability of the ocean to act as a giant sponge, soaking up carbon and heat, depends on the movement within its depths, including giant underwater waves and turbulence. These movements can either lock away carbon and heat deep in the ocean or bring them back to the surface, affecting global climate patterns. Understanding this process is crucial because it influences how we predict and respond to climate change, making the ocean an unsung hero in our fight against global warming. For you, living on this planet, grasping the ocean's role in storing carbon and heat could inspire actions and innovations for a sustainable future.

Diapycnal mixing
This is when water mixes across different density layers in the ocean. Imagine pouring oil and water into a glass; they naturally separate into layers. Diapycnal mixing is like stirring that glass, causing the oil and water to mix.

Anthropogenic carbon
This term refers to carbon dioxide emitted by human activities, such as burning fossil fuels. It's like the smoke from cars and factories adding invisible layers of blankets around Earth, warming it up.

Turbulence
In the ocean, turbulence is the chaotic, unpredictable movement of water. Think of it as the underwater version of a windy day, where currents and waves move in all directions.

Atlantic meridional overturning circulation (AMOC)
This is a major ocean current system that moves warm water from the tropics to the North Atlantic, where it cools, sinks, and flows back to the equator. Picture it as a giant conveyor belt, carrying heat across the ocean.

Remote sensing
This technology allows scientists to study the ocean from a distance, using satellites or aircraft. It's like having a high-tech pair of binoculars that can see the color and temperature of the ocean from space.

Autonomous floats
These are robotic devices that can move through the ocean, collecting data on temperature, salinity, and currents. Imagine underwater drones exploring the ocean's hidden depths on a treasure hunt for scientific data.
