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 2021 will be organised and sponsored by the Domain Science of the Dutch Research Council NWO.

This is the 17th time the NAC is being organised.​ In 1992 NAC was founded by KNAW, KNGMG and NWO.  


Videorecordings of NAC 2021 still available for participants.

These recordings include the keynotes, parallel session presentations, several workshops, and of course the award ceremonies. The posters are available for viewing too.

In the meantime, do enjoy NAC 2021 or alternatively the above photograph of Weathered dolerites & quiver trees - Mesosaur fossil bush camp (Spitzkop farm, Keetmanshoop, Namibia). "Imagine Father James (‘Vader Jacob’) played on these dolerite ‘figures” which are part of the Paraná-Etendeka related giant dyke swarms, locally also known as the Giant’s Playground." wrote Els Ufkes  (VU Amsterdam) when she submitted this photo to the NAC 2019 photo competition.
