Microseism: A Messenger of Earth’s Ocean Environment

Ocean activity generates low-frequency seismic waves, known as microseisms, propagating across the world. These waves carry valuable information about their sources (i.e. ocean activity) and the  media they travel through (including crustal structures). Understanding microseism amplitudes is fundamental not only for imaging crustal structures but also for gaining insights into the microseism source. My presentation will introduce our research about modulation effects of  ocean bottom sediments on the amplitudes. Furthermore, I will present how to infer the source information from microseism amplitudes and discuss the potential for using microseisms to monitor changes in the Antarctic cryosphere.
