Title

Teleseismic tomography model of Macquarie Island and surrounding region

Abstract

3-D P-wave velocity model of the crust and uppermost mantle beneath Macquarie Island and surrounding region from teleseismic tomography. The dataset contains data and files that can be used to plot the teleseismic tomography model that was produced from broadband seismic data collected as part of the Macquarie Ridge experiment undertaken in 2020-2021 (NERC grant NE/T000082/1). The model region approximately spans 53° - 56° South and 157° - 160.5° East. The data can be accessed from the AusPass data portal at https://auspass.edu.au/networks/macquarieridge.html. The information contained in this repository can be used to plot or otherwise use this model for other purposes. The dataset includes a detailed description of the format in a README file.
