Many geologists will have to, and indeed want to, work overseas at some point in their careers. The global opportunities offered by research and working within the geosciences is a big attraction when deciding to study geology and join the profession. In many cases working internationally will often mean partnering with host-country agencies and industries (e.g., universities, geological surveys, water ministry, volcano observatories, mining companies). These partnerships can fall on a spectrum between fruitful long-term relationships and difficult, fractious relationships. In this latest series of blogs we will explore this theme of best-practice when engaging internationally.
