New data on seismology of underwater volcanoes of the Bransfield Strait in Antarctica
Scientists from the University of Granada (UGR) have managed to obtain images of the structure of two of the most important submarine volcanoes of the Bransfield Strait, in Antarctica, within the framework of the Spanish Antarctic Campaign 2018-2019, which has just ended. This work is in collaboration with NOAA PMEL's Acoustic Program. The story is originally in Spanish.
