Mars’ gravitational pull on Earth may be influencing the climate on our planet, new research hints.
Geological evidence tracing back more than 65 million years and taken from hundreds of sites across the world suggests that deep-sea currents have repeatedly gone through periods of being either stronger or weaker. This happens every 2.4 million years and is known as an “astronomical grand cycle.”
The stronger currents, known as “giant whirlpools” or eddies, may reach the seafloor at the deepest parts of the ocean, known as the abyss. These powerful currents then erode away at the large pieces of sediment that accumulate during calmer periods in the cycle, according to research published Tuesday (March 12) in the journal Nature Communications.
