A team of UH geologists has been awarded 2.5 million CPU Hours by the National Science Foundation for use of its supercomputer to search for the remains of a lost ocean deep below the Earth s surface.

Researchers at Stevens Institute of Technology have developed a new machine learning-powered platform, known as OC-SMART, that can process ocean color in satellite images 10 times faster than the world s leading platform. The work, which will be adopted by NASA, is one of the first machine learning-based platforms in ocean color analysis that can process both coastal and open ocean regions globally to reveal data on sea health and the impact of climate change.

Geologists have developed a new theory about the state of Earth billions of years ago after examining the very old rocks formed in the Earth s mantle below the continents.
Assistant Professor Emma Tomlinson from Trinity College Dublin and Queensland University of Technology s Professor Balz Kamber have just published their research in leading international journal,
Nature Communications.
The seven continents on Earth today are each built around a stable interior called a craton, and geologists believe that craton stabilisation some 2.5 - 3 billion years ago was critical to the emergence of land masses on Earth.
Why power wires sometimes ‘dance’ to an undetectable breeze
Share on Facebook
Print article On these quiet, still days, as winter plods on, Alaskans tend to notice any movement outside their windows, such as dancing power wires strung between poles. The answer as to why the wires bounce is in Neil Davis’ “Alaska Science Nuggets.” First, though, a refresher on that book a compilation of 400 of these columns and why you are reading this right now. Neil Davis was a do-all scientist at UAF’s Geophysical Institute from the 1960s to the 1980s. He started this column in 1976 at the urging of a newspaper editor.
Fin whale song - one of the strongest animal calls in the ocean - can be used as a seismic source for probing the structure of Earth s crust at the seafloor, researchers report.
