A new study has uncovered a 2.4-million-year cycle associated with deep-sea currents, and the orbits of Earth and Mars.
Could the interaction between Earth’s orbit and Mars be influencing deep-sea circulation? A new study has uncovered a 2.4-million-year cycle associated with deep-sea currents and the orbits of
As per the press release, the researchers also discovered links between times of higher solar radiation and a warmer environment.In this study, the researchers used over 50 years of scientific drilling data from across the globe. Interestingly, scientists discovered variations in deep-sea currents over a 2.4-million-year period known as astronomical grand cycles. Researchers have linked this cycle to Earth and Mars’ interactions with the Sun.“The gravity fields of the planets in the solar system interfere with each other and this interaction, called a resonance, changes planetary eccentricity, a measure of how close to circular their orbits are,” said Dietmar Müller, the co-author from the University of Sydney.
Moreover, the AMOC is important in producing the Gulf Stream, a strong, warm ocean circulation that drives climatic patterns, especially in Europe.
