The NAC conferences (Nederlands Aardwetenschappelijk Congres) bring together all fields of research within the Earth Sciences. The NAC conferences aim to provide a true interdisciplinary forum for discussion and for young researchers to present their results in a way that is accessible to a broad audience. NAC 2020 will be organised and sponsored by the Domain Science of the Dutch Research Council NWO. This is the 16th time the NAC is being organised. In 1992 NAC was founded by KNAW, KNGMG and NWO.
