Computational science (taken broadly and which could include developing new software, significant use of compute resources, or complex data management) is an increasingly important part of the Earth sciences, but we often lack the opportunity to discuss the details of the computational methods and tools we use. The aim of these meetings is to provide space to discuss these details across the traditional research areas in the Earth sciences. Ideally the science background for these talks will be approachable by anybody in the Department, but the computational side will be more detailed than what is typically covered outside individual research groups. We also include some broader discussion of ideas and the literature as well as some training activities.
