The Earth’s oceans are crisscrossed with roughly 1.2 million km of fibre optic telecommunication cables — enough to girdle the planet 30 times. Researchers have now succeeded in using fibre in a submarine cable as a passive listening system, enabling them to listen to and monitor whales.
Everyone knows there’s just too much carbon dioxide in the atmosphere — and we’re heating up the planet at an unprecedented pace. In the third episode of NTNU’s new English-language podcast, 63 Degrees North, we’ll hear what Norwegian researchers are doing to help address this problem.
Ten years ago, the Deepwater Horizon accident in the Gulf of Mexico killed eleven men and resulted in the largest accidental oil spill in history. Years of investigations concluded that the drilling crew missed critical warning signals that would have stopped the problem. A new analysis suggests that wasn’t the case.
During the time of Darwin, anthropogeny was the study of human origins. Its sub-discipline paleoanthropology has since taken over, which focuses on fossils found in dry parts of Africa. These fossils don’t tell us much about why or where humans actually evolved.
Humankind will need to harness carbon capture and storage technologies to help keep global warming to 2 degrees C or less. New research shows that there’s plenty of room to store captured CO2 — in offshore geologic rock formations.
For the first time ever, researchers have been able to peek deep into the mantle of the Earth under an ultraslow mid-ocean ridge, where they have been able to observe mantle melting and growth of the Earth’s crust.
