New research provides further evidence that rocks representing up to a billion years of geological time were carved away by ancient glaciers during the planet's "Snowball Earth" period, according to a study published in Proceedings of the National Academy of Sciences. The research presents the latest findings in a debate over what caused the Earth's "Great Unconformity"—a time gap in the geological record associated with the erosion of rock up to 3 miles thick in areas across the globe.

It is worth repeating that scientists know more about Mars, Venus, and the dark side of the moon than they know of Earth’s ocean depths. To date, less than 20 percent of the ocean floor has been mapped—13 percent in just the past four years. But scientists would like to map it all by 2030. It’s an essential undertaking, but it’s going to take dedicated effort, public support, and government funding. Such a project can be accomplished only through dedicated global cooperation. The payoff sta

Land cover classification remains challenging. However, more very high-resolution images are available to create quality reference data. In addition, efforts to improve transparency and accountability in the machine learning model are becoming an important research topic. I have published a book on ‘Data-centric Explainable Machine Learning for Land Cover Classification: A Practical Guide in R.’ The book is for those interested in improving land cover classification using a data-centric explaina

An underwater volcano off Tonga erupted on Saturday, triggering tsunami warnings and evacuation orders in Japan and causing large waves in several South Pacific islands, where footage on social media showed waves crashing into coastal homes. Japan's meteorological agency issued tsunami warnings in the early hours on Sunday and said waves as high as three metres (9.84 feet) were expected in the Amami islands in the south. Waves of more than a metre were recorded there earlier.   Pub

Hi. What is a basic method to export worldmap layers such as coastlines, but wrapped on a 3d globe, for further use with computer graphics tools ?
