Researchers have discovered a previously unknown climate mechanism during the Cretaceous period, linking continental movement with disruptions in ocean currents that affected temperature gradients. This study not only deepens our understanding of ancient climate dynamics but also emphasizes the role of oceanic processes in today’s climate system. A groundbreaking study has uncovered a previously unknown mechanism that significantly influences Earth’s climate. The research was conducted by Hebrew University’s Ph.D. candidate, Kaushal Gianchandani, under the guidance of Professors Nathan Paldor and Hezi Gildor from the Institute of Earth Sciences at the Hebrew University, in collaboration with Prof. Ori Adam and Sagi...

Watch in awe as the world's eddying ocean currents swirl in a Van Gogh-esque grandeur. Click here to watch the three minute "Perpetual Ocean" video on YouTubeA stunning new animated video produced by NASA and the Jet Propulsion Laboratory’s Estimating the Circulation and Climate of the Earth showcases the flow of the world's ocean currents swirling in a captivating splendor. The video, titled "Perpetual Ocean," takes an astronaut's view, as if the viewer is in a waltz-like dance orbiting around the Earth. The flow of the ocean currents in the presentation are derived from real data collected over two years...

New supercomputer studies suggest it is "very likely" ocean currents will carry oil from the Deepwater Horizon spill in the Gulf of Mexico around the tip of Florida and thousands of miles up the U.S. East Coast this summer, researchers announced Thursday. "It is truly a simulation, not a prediction," said Terry Wallace, principal associate director for science, technology and engineering at the Los Alamos National Laboratory in New Mexico, which collaborated on the project. "But it shows that when you inject something into the Gulf, it is likely to have much larger consequences." So far the oil has been...

New tracer demonstrates carbon cycle changes preceded thermohaline changes Scientists from the Lamont Doherty Earth Observatory (LDEO) have provided new evidence that ocean circulation changes lagged behind, and were not the cause of, major climate changes at the beginning and end of the last ice age (short intervals known as glacial boundaries), according to a study published in the March 2005 issue of Science magazine. Both ice sheet volume and the “global carbon budget,” the amount of carbon stored in deep ocean reservoirs compared to that on the earth’s surface, changed before ocean circulation patterns changed, according to evidence from...
