23 Mar - 24 Mar Utrecht, The Netherlands

NAC 2023

The NAC conference brings together all research fields within the Earth and Environmental Sciences.

NAC 2023 will be held on 23 March & 24 March at Van der Valk Hotel Utrecht, Utrecht.

About NAC 2023

NAC 2023 welcomes you back on Thursday 23 and Friday 24 March 2023. Reconnect face to face with colleagues in Van der Valk Hotel, Utrecht. The 19th edition of NAC (Nederlands Aardwetenschappelijk Congres) brings together the research fields within the Earth and Environmental Sciences. The event aims to continue to provide a true interdisciplinary forum for discussion and for young scientists to present their research results to a broad audience.

The NAC was founded in 1992 by KNAW, KNGMG, and NWO. Since then, 18 editions of NAC were held with scientists from all research fields within the Earth Sciences. NAC 2023 will be organised and sponsored by the Domain Science of the Dutch Research Council NWO.

NAC 2023 is complying with the current measures announced by the Dutch government to prevent any further spread of COVID-19.


The Programme Committee of NAC 2023 is tasked with compiling a broadly appealing programme. This Programme Committee comprises scientists from both Earth and Environmental Sciences. 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 each day, with ample time during the programme for visiting the posters.


Based on the keywords selected during submission of abstracts (see list below), the total number of abstracts and the topics submitted, the Programme Committee will arrange the abstracts into broader overarching parallel sessions. The themes of these parallel sessions will e.g. focus on specific or timely issues in the fields of Earth and Environmental 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 and Environmental 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 a 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 not later than Monday 16 January 2023, 17:00 h CET. 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 abstracts received before Monday 16 January 2023, 17:00 h CET. 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 June 2022 the final program will be announced on the website and 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 you 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. Starting 2020, posters will be displayed only on one of the conference days, linked to the topics of parallel sessions. You will be informed beforehand which day you are expected to present your posters. 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 made by early-career scientists, so if you take note of these tips you might increase your chances of winning! Please note that posters can only be presented in A0 portrait (vertical) orientation of 841 x 1189 mm (width x height). 

Abstract keywords

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

Team Science Award

The NWO Team Science Award rewards the most inspiring and successful team of researchers from various disciplinary fields, who jointly take on a scientific challenge in which their individual strengths and expertise demonstrably reinforce each other. Each year at most three team will receive the award of 10k€. The prize money is intended for activities with relation to the team.

Communication Initiative Award

The NWO Communication Initiative Award rewards initiatives of successful and inspiring science communication by scientists. Per year at most three initiatives of individuals or team receive the award of 10k€. The prizemoney is intended for activities with relation to the initiative.

Stairway to Impact Award

The NWO Stairway to Impact Award rewards scientists who take effective steps to utilise their scientific findings to tackle a societal problem and/or to make an economic contribution. The journey is more important than whether the final goal has been achieved. The award is a sum of 50k€. The money must be used to contribute to the goal for which the award has been presented.

The KNGMG will award its Escher- & Jelgersma Prizes and its NJG publication Prize. 

Escher Prize 

The Escher Prize, established in 1994, is named after the Leiden Professor of General Geology Prof. Dr. B.G. Escher (1885-1967). The prize can be awarded annually to the author(s) of the best MSc thesis in (applied) earth sciences in the broadest sense of the word, assessed by the Jury as the best graduation thesis.

Jelgersma Prize

Since 2016, the KNGMG annually awards the Jelgersma Prize for the best Dutch Earth Science bachelor's thesis. The prize is named after Dr Saskia (Kiek) Jelgersma (1929-2012). We hope that her independent way of thinking and acting and her excellent work will serve as an example to bachelor students. The prize can be awarded annually to the author(s) of the best BSc thesis in (applied) earth sciences in the broadest sense of the word, assessed by the Jury as the best graduation thesis. 

NJG publication Prize 

Netherlands Journal of Geosciences – Geologie en Mijnbouw - is a scientific international quarterly journal, which publishes papers on all aspects of geoscience, provided they are of international interest and quality. The Netherlands Journal of Geosciences will announce the NJG publication Prize to the best paper of the year.
