Researchers discovered an invisible biogeographic barrier in the North Atlantic that influences the distribution of Botrynema jellyfish, revealing how deep-sea currents and a 'soft barrier' in water conditions shape where different morphs of this Arctic jellyfish can live, with the knobbed form able to reach subtropical waters near Florida likely via deep currents.
Scientists have discovered a previously undetected 2.4-million-year cycle in deep sea currents, linked to global warming and cooling driven by the gravitational interaction between Earth and Mars. This cycle affects the amount of sunlight Earth receives and has an impact on climate. By analyzing sedimentary sequences from over 200 drill sites, researchers identified hiatus cycles over the past 65 million years, showing that the vigor of deep-sea currents fluctuates in 2.4 million year cycles coinciding with changes in the shape of Earth's orbit. The findings suggest that more intense deep-ocean eddies may counteract potential ocean stagnation in a warming world, and the interaction between Earth-Mars astronomical influence and human-driven global warming will depend on future greenhouse gas emissions.
Researchers have discovered a previously undetected 2.4-million-year climate cycle driven by the gravitational interaction between Earth and Mars, affecting deep-sea currents and global warming. By analyzing deep-sea sediment records spanning 65 million years, the study found evidence of a connection between the changing orbits of Earth and Mars, past global warming cycles, and the speeding up of deep-ocean currents. The findings suggest that warmer oceans have more vigorous eddy-driven circulation, which may play a crucial role in counteracting potential ocean stagnation in a warming future.
Scientists have discovered a surprising link between Mars and Earth's oceans, revealing that deep-sea currents have been influenced by 2.4 million-year climate cycles caused by the gravitational resonance between the two planets. This interaction has led to the weakening and strengthening of ocean currents, impacting the shape of their orbits and distance from the sun. While these natural climate cycles affect warming and ocean currents on Earth, they are not linked to the rapid heating caused by human activities. The study provides valuable insights into ocean circulation changes and the potential mitigation of impacts from a collapse of the Atlantic Meridional Overturning Circulation.
