West Antarctic Rift System

Our understanding of the Antarctic continent and its interaction with the cryosphere is ever growing. Seismic imaging is an important tool used in this endeavor. Within the last decade, the number of broadband stations deployed throughout continent has risen drastically due in large part to the POLENET project and temporary arrays. More recently, stations deployed on the floating Ross Ice Shelf (RIS) have allowed us to increase resolution in some of the key portions of Antarctica.

The goal of this project is to better image, and understand, the crust and upper mantle structure of the Ross Sea Embayment in order to gain insight into the rifting history of West Antarctica. Screen Shot 2018-03-17 at 1.06.18 PMFrom White-Gaynor et al., 2019 / EPSL
