NAC 2020

The NAC (Nederlands Aardwetenschappelijk Congres) conferences bring together all fields of research within the Earth Sciences.

NAC 2020 will be held on 12 March 2020 & 13 March 2020 at Van der Valk Hotel Utrecht, Utrecht.

About NAC 2020

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.​ 

Read the report on the succesfull NAC2019 here.  

Join us on 12-13 March 2020 to explore, interact and get inspired. We welcome contributions from all branches of the Earth Sciences. The programme, meticulously compiled by the Programme Committee NAC 2020, will consist of plenary sessions with invited (inter)national keynote speakers, parallel sessions dedicated to oral presentations, and poster sessions. Enjoy these opportunities to network and set up new collaborations with your colleagues.


The Programme Committee of NAC 2020 is tasked with compiling a broadly appealing programme. Contributions will be scheduled as oral presentations that take place in parallel sessions spread over the two days of the congress. In addition there will be dedicated poster sessions, but there is also ample time during the programme each day for visiting the posters.

Based on the keywords linked to the abstracts, the total number of abstracts and the topics presented, the Programme Committee will arrange the submitted abstracts into broader overarching thematic sessions. The themes of these parallel sessions will e.g. focus on specific or timely issues in the field of Earth Sciences, or they can aggregate contributions with a methodological or topical similarity. The committee will then decide if an abstract is accepted as an oral or poster presentation within one of those sessions. As the conference will be an interdisciplinary meeting ground for geoscientists, this procedure aims at encouraging researchers from all fields in Earth Sciences to connect, interact and present their progress of research. 

How to submit an abstract

You will have to register first. Please select the option ‘yes’ under ‘submit abstract’. You will receive an unique link by email after you have completed the registration process. This link can be used to login and submit your abstract. Abstracts (max. 250 words) can be submitted until Monday 13 January 2020. Please note that the official language of the conference and for submitting abstracts and giving oral and poster presentations will be English. 


The Programme Committee will define the themes of the parallel sessions and compile the conference programme based on the abstract received before Monday 13 January 2019. From all received abstracts, a selection of authors will be invited to give an oral presentation. By default, authors of the other abstracts will be offered the option of a poster presentation. In February 2019 the final program will be announced on the website and successful applicants will receive an invitation with instructions for preparing their oral or poster presentations.

Instructions for oral presentations

Oral presentations are scheduled in parallel sessions spread over the two days of the congress. Authors are allotted 15 minutes for presenting, including time for questions and discussion. Authors will be asked to upload their presentation prior to the start of their parallel session. We have listed some tips to help your prepare your talk.

Instructions for scientific poster design

At the NAC you will have an excellent opportunity to practise your academic skills, such as giving poster presentations and poster pitches. When it comes to designing a scientific poster we have compiled a few ‘best practices’ that you can read on this page. A poster prize will be awarded to the three best posters, so if you take note of these tips you might increase your chances of winning! Authors will be invited to present their posters during specific time slots, based on the even/odd number of the poster numbering. Please note that posters can only be presented in A0 portrait orientation of 841 x 1189 mm (width x height). 

Abstract keywords

We welcome contributions from all branches of the Earth Sciences. Abstracts can be submitted using one or two the following keywords:


During the conference various prizes will be awarded. The winners of the prizes will be announced during the plenary session of the NAC. More details about the awards and award ceremonies are given below.

Vening Meinesz Prize

Every other year at NAC, NWO awards the Vening Meinesz Prize. This personal award is intended for early-career researchers in Earth Sciences. The award is named in honour of Prof. Dr Felix Vening Meinesz (1887-1966), one of the founders of Dutch Earth Sciences and of the Dutch Research Council (NWO). He became well-known for his research into gravity, for which undertook a dozen scientific expeditions on board submarines of the Royal Netherlands Navy. NWO awards the prize biennially from his financial legacy, aiming to stimulate promising earth scientists. The next Vening Meinesz Prize will be awarded in 2020. Read more about this award at the NWO website (in Dutch).

Poster prize

Most presentations at NAC will be in the format of a poster presentation, like on many of the international conferences in Earth Sciences. As such the poster prize aims to award those participants that excel in presenting their scientific work via this presentation format. The top-three posters will be awarded € 250 (first place), € 150 (second place) and € 100 (third place). The selection of the top-three will be performed by a dedicated poster jury, comprising the chair and a member of the Program Committee and a representative of the conference organisers. In order to be eligible for winning the poster prize, it is required that the first author is present at the pleneray session on Friday morning. Read more about the assessment criteria for the poster prize.

Photo competition

The photo competition has been a recurring event at the NAC conferences. Pre-registered conference participants can take part in this competition by submitting one original photo on any theme related to Earth Sciences (see also the terms and conditions). The pre-selection phase of the competition during the two months leading up to the conference, and is open for submissions from 14 December to 14 February. Please note that you must be registered for the conference before 14 February in order to take part in the contest. Submitted photos will be judged first by an expert jury to select a top-10. These ten images are printed in large format and will be prominently exhibited at the conference venue. The overall winner will be selected by public vote. The winning photo will be featured in the Geo.Brief magazine of the KNGMG and the winner will receive a free registration for next year’s NAC.

Prizes by other organisations:
NJG publication award

Every two years the Editorial Board of the Netherlands Journal of Geosciences presents the Publication Award, recognizing the best NJG paper first-authored by a young and promising scientist. Besides the award document the award includes a book voucher and the author is offered publication space in the Geo.Brief magazine of the KNGMG. 


The Escher Prize (in Dutch: Escherprijs) was established in 1994 and was named in honour of the Leiden professor in ‘Algemene Geologie’ Prof. Dr B.G. Escher (1885-1967). The prize is awarded annually by an expert jury from the KNGMG to the author(s) of the best or most original thesis in (applied) Earth Sciences in the broadest sense of the word.


The Jelgersma Prize (in Dutch: Jelgersmaprijs) was established in 2016 and was named in honour of the dr. Saskia (Kiek) Jelgersma (1929-2012). The prize is awarded annually by the KNGMG to the author(s) of the best or most original Bachelor thesis in (applied) Earth Sciences in the broadest sense of the word. With this the KNGMG puts emphasis on the importance of the Bachelor thesis as the first piece of real science by students.
