A geochemist who studies the workings of the deep earth and their influence on some of the world’s most explosive volcanoes has been awarded a $500,000 MacArthur Fellowship. Terry Plank, a researcher at Columbia University’s Lamont-Doherty Earth Observatory, joins novelist Junot Diaz, war correspondent David Finkel and filmmaker Natalia Almada in this year’s batch of MacArthur Fellows, who will receive $100,000 a year for five years, no strings attached. Maria Chudnovsky, a mathematician at Columbia’s Engineering School who studies the fundamentals of graph theory, also received a genius grant.
What is a plate? We undertake a comprehensive analysis designed to significantly advance our understanding of the structure and evolution of oceanic plates.
Layered intrusions in East Greenland, mostly close to the contact between PreCambrian gneisses and Tertiary flood basalts, are commonly several million years younger than the flood basalts.

Starting today, armchair explorers will be able to view parts of the deep ocean floors in far greater detail than ever before, thanks to a new synthesis of seafloor topography released through Google Earth. Developed by oceanographers at Columbia University’s Lamont-Doherty Earth Observatory from scientific data collected on research cruises, the new feature tightens resolution in covered areas from the former 1-kilometer grids to just 100 meters.

Scientists using underwater sensors to explore Lake Rotomahana in New Zealand have uncovered remnants of the Pink Terraces,” once considered the eighth natural wonder of the world.

What causes the peaks and valleys of the world’s great mountains? For continental ranges like the Appalachians or the Northwest’s Cascades, the geological picture is clearer. Continents crash or volcanoes erupt, then glaciers erode away. Yet scientists are still puzzling out what makes the highs high and the lows low for the planet’s largest mountain chain, the 55,000-mile-long Mid-Ocean Ridge.
