![]() The ground temperature at the summit reaches 80☌ in some places enough to run such a generator. The generator uses the heat flow to create a voltage difference that produces electricity. All it takes is a difference in temperature, e.g. Not a new technology in itself, but so far unused in research on the icy continent. A few years ago, he came across a way to get around the power problem – using a thermoelectric generator that converts heat into electricity. Infrared spectrometer for measuring gas emissions sited at the crater rim on Erebus, pictured before and after a spell of weather Thermal emission from Erebus’ lava lake detected by Hyperion onboard NASA’s Earth Observing-1 spacecraft. He wanted to use a thermal camera to observe the magma year-round, but has so far failed because of the problem of power supply. Ice towers beneath the summit plume emitted by Mount Erebus. Since 2009, Nial Peters, an engineer at University College London and lead author of the study, has been investigating Mount Erebus’ lava lake. Apart from that, the volcano keeps spewing magma bombs that solidify as they fall and can destroy instruments deployed on its flanks. Scientists also use wind turbines to generate energy, but these can be destroyed by the strong storms. As soon as the light failed, the instruments soon stopped working. At Mount Erebus in Antarctica, these measurements were previously only possible as long as the sun provided the necessary energy. Volcanologists around the world continuously measure ground vibrations, rising gases, the temperature of flowing magma and other parameters throughout the year to investigate what is happening inside volcanoes. ![]() Historical expedition reports indicate that the lava lake has existed since at least the early 20th century, which is quite extraordinary, according to Philip Kyle, professor emeritus at the New Mexico Institute of Mining and Technology and co-author of the study. It is one of the few volcanoes with an open lava lake at its summit, making it a unique natural laboratory for volcanic research. Mount Erebus is the southernmost active volcano on Earth and the most active volcano in Antarctica. Researchers from the United Kingdom and the United States have presented details of how this works in a new study.

While this is ensured to some extent in summer with the help of solar panels, it can hardly be guaranteed during the long polar night. The central aspect for data collection is the power supply. Extreme cold and violent storms not only take their toll on the researchers themselves, but also on their measuring instruments. Standing at 3794 metres, Mount Erebus is the second highest volcano in Antarctica after Mount Sidley and was discovered by the Polar explorer James Ross in. Field research in Antarctica confronts scientists with major challenges in many respects.
