NAC 2021 will be held Online on 08 April 2021 & 09 April 2021.
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.
NAC goes digital!
NWO is complying with the measures announced by the Dutch government to prevent any further spread of Covid-19. As these measures make a normal NAC edition impossible we will make the most of the technological possibilities to create a great online NAC 2021! More information will follow soon on this website.
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 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 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.
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 not later than Monday 13 January 2020, 23:59 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 13 January 2020, 23:59 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 February 2020 the final program will be announced on the website and applicants will receive an invitation with instructions for preparing their oral or poster 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.
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).
We welcome contributions from all branches of the Earth Sciences. Abstracts can be submitted using one or two the following keywords:
Atmospheric sciences extends from the large-scale dynamical/meteorological processes and systems in the atmosphere to the smaller scales of turbulent mixing, both in time frames that span from centuries (e.g. related to climate research) to shorter scales of seconds. Covered under this keyword are contributions that e.g. focus on studies of atmosphere composition, aerosol and cloud physics, in-situ or laboratory studies of gas-particles interactions and chemical reaction kinetics and large-scale infrastructure.
Biogeosciences covers biosphere-geosphere interactions in the present, past and in the future, biogeochemical cycles and research at the interface of (micro)biology and earth sciences. It integrates biological, chemical, and physical and its focus goes beyond the established scientific approaches embracing multi- and interdisciplinary understandings of bio-geosphere functioning in space and time. Experimental, conceptual, and modelling approaches are welcomed and the development and calibration of proxies and their use to reconstruct palaeoenvironments.
The dynamics of currents, wave and tides in interaction with coastal sediment, bathymetry and morphology create intricating ever changing landscapes. Humans in the modern situation tend to make heavy use off these coastal systems, especially in places such as The Netherlands. This key word covers studies of the morphodynamic of shelf seas, beach coasts, tidal inlets and deltaic river channels – combining field data and numeric modelling with the occasional flume experiment and so on. It also covers studies of human design, engineering, forms of nourishment. It also covers bio-sedimentary and ecological aspects of the dynamics of these coastal systems in natural and in human-interfered situations.
The cryosphere are those parts of the Earth that are subject to prolonged periods of temperatures below the freezing point of water. These include glaciers, frozen ground, sea ice, snow and ice. Research topics can focus solely on the cryosphere (e.g. land/sea ice mass balance), or on interactions with other components of the climate system, both addressing theory, observation and modelling.
Understanding of the past evolution and current thermal, dynamical and chemical state of the Earth's deep interior and of the effect that the interior has on the structures and processes observed at the surface of the Earth. The 'deep interior' is generally considered to be the core and lower mantle, but interest may extend to the surface, for example, in the study of mantle plumes or dynamics of descending lithospheric slabs. This keyword serves to tag conference contributions more explicitly in which the deep interior of planet Earth is addressed.
Earth scientific studies increasingly benefit from the accessibility and use of Earth observation satellite data, (often commercial) small-sat constellations and the increasing capabilities of drones and. Exchange information on the use of Earth and aerial observation and share the best practices and available tools for Earth science applications, including upcoming BigData/BigScience issues.
There are a number of general trends that currently affect the teaching and learning environment for Earth Scientists, varying from a gradual shift in the way humanity is exploring and exploiting our planet, via changes in the labour market asking for a new type of professional, to the introduction of new styles of teaching such as blended learning and flipping the classroom. Abstracts covered under this keyword, in some way or another, respond to such trends and (may) result in enhanced teaching and learning, which includes best practices, innovative ideas and suggestions for future improvements in tertiary education. In addition, abstracts are also invited that focus on outreach to the general public and the utilisation of our geoheritage (i.e. university or museum collections) in teaching and/or scientific studies.
The safe, efficient and cost-effective use of the subsurface in environmentally sustainable ways for the exploration and exploitation of natural resources and the construction of transport and storage infrastructures requires a thorough knowledge of the geological and geophysical heterogeneity. Covered by this keyword are contributions on case studies and innovative approaches to construct static earth models based on, e.g., process-based numerical forward modelling, seismic, well logs and core studies, and hybrid outcrop – stochastic – laboratory studies as well as dynamic models simulating processes in and around natural resource exploitation as well as underground infrastructure facilities. In addition, studies specifically focussed on sedimentary basins as hosts of important natural resources like coal, gas, oil, ore deposits, groundwater and geothermics are welcomed. This keyword also matches well to studies embedded in the recent KEM and DeepNL research programs.
These keywords cover studies that are fundamental to the study of the solid Earth. Topics can include studies related to the Earth’s mantle; oceanic and continental crust; the formation and crystallisation of magmas; the chemical compositions of igneous, metamorphic and sedimentary rocks; studies of volcanoes and various types of volcanism. While mostly fundamental in nature, applied topics include pollution of the atmosphere, surface or subsurface waters, the formation of ore deposits, and environmental impacts of volcanism (both subaerial, submarine as subglacial).
This keyword covers all aspects and methods that focus on determining the timing of events and processes as well as their rates in the geological record. Methodological development studies of dating techniques, as well as studies applying and integrating techniques to reduce chronometric uncertainties, or studies on standardization or studies comparing different dating methods are covered by this keyword.
The fields of Geodynamics, Geophysics and Geodesy together cover many aspects of studying the Earth’s surface, lithosphere, mantle, and core. This encompasses observations, imaging, theory, numerical modelling (simulations) and laboratory modelling (experiments), over shorter and longer timescales, involving rheological, seismic, paleomagnetic and gravitational aspects. At the surface, this affects. sea-level rise, the tides, changing ice masses and global water circulation. Observing and measuring at the Earth’s surface and shallow lithosphere, provides insight into spatial and temporal patterns of geophysical processes and deformations also in the deeper parts of the earth. Topics therefore span from measurement systems to the actual investigation of geophysical processes.
Geomorphology is the study of land-surface features and the dynamic processes that shape them. At the heart of geomorphology is the understanding landform history and dynamics, and predicting future changes through a combination of field observations, physical experiments, and numerical modelling. Research focussed on processes that ‘build topography’ as a result of the interplay between the effects of tectonic forces and processes that modify the terrain, such as weathering, erosion through running water, waves, glacial ice, wind and gravitational forces. This also includes human influences on geomorphological processes and the societal application of geomorphological research.
Developments in instrumentation, technology, methods and data handling used in any field of the geosciences, aiming to advance instrumentation and data systems and to share experiences and approaches with other subject areas.
Monitoring, modelling and prediction are basic issues in hydrology and geohydrology. Research is focussed on quantitative and qualitative aspects of fresh and saline groundwater and surface water systems, their dynamics and their interrelationships with the surrounding geology and ecosystems. This includes interactions between hydrology and geomorphology (e.g., erosion, sedimentation, groundwater systems), the relationships between hydrology and soils or sedimentary reservoirs, as well as the interaction between the hydrosphere and the biosphere (e.g., ecohydrology, wetlands). This may also include research into the management and operation of water resources by societies in various parts of the world, reservoir engineering, civil engineering, soil sciences en environmental sciences.
Research pertaining to the International Ocean Discovery Program (IODP), an international marine research collaboration dedicated to advancing scientific understanding of the Earth through drilling, coring, and monitoring the subseafloor, and the International Continental Scientific Drilling Program (ICDP), a multinational program to further and fund geosciences in the field of Continental Scientific Drilling.
This includes the geological and geophysical processes that can be hazardous and can produce damage to the environment and to the society. Underlying aims can be improving the understanding of the evolution of the processes or discuss new technologies, methods and strategies to mitigate their disastrous effects. Specific hazards include: hydro-meteorological processes, volcanism, landslides, earthquakes, sea and ocean, snow-avalanche and glacial and wildfires. In addition social aspects of the before mentioned hazards can include studies addressing topics such as development sustainability, emergency, warning, and after-disaster resilience.
Nonlinearity is broadly found in all branches of the geosciences. Covered by this keyword are studies of, new methodologies, new modelling or new data analysis techniques related to nonlinear paradigms whose applications broadly applicable to various subdisciplines. This can include deterministic chaos, tipping points, nonlinear waves, similarity across scales, network theory, stochasticity, predictability and its limits, pattern formation, self-organised criticality, extreme events.
This keyword broadly covers the various ocean science disciplines on global, regional and local (e.g. Waddenzee) scales. Research topics can focus solely on the oceans (e.g. large-scale circulation, coastal oceanography, sea level change), or on interactions with other components of the climate system, both addressing theory, observation and modelling.
Excavation of ancient life and traces of human ancestry is intimately linked to earth sciences: the local circumstances trapping and preserving articulated fossil records and archaeological sites (taphonomy), the regional to global circumstances explaining evolutionary and cultural developments, the strategies of discovering and documenting find sites. The keyword is to cover bone-bed, cave-fill and lake-rim material studies (e.g. dinosaur excavation, hominin sites), as well as landscape-archaeological and multiproxy geoarchaeological work involving the modern human species in subrecent times in younger Pleistocene and Holocene palaeoenvironments.
Studies including the study of, any kind of, climate archive from rocks to ocean cores, speleothems, ice cores, chronicles, to instrumental records are welcomed. Besides observations, climate modelling on all time scales from the deep past to the future are areas covered under this interdisciplinary abstract keyword.
Recent advances in (Dutch) planetary geoscience are covered by this keyword and this includes geological, morphological, geophysical, astronomical and geochemical studies of planet- and moon interiors, surfaces, and atmospheres; and interdisciplinary contributions on the origins and the evolution of the solar system and exoplanetary systems. This covers an equally broad range of methodologies for studying these topics, such as ground-based observations or space mission exploration (i.e. remote sensing), numerical and analogue modelling, extra-terrestrial sample analysis, and terrestrial analogue (field) studies.
These topics centre on the development of static and dynamic geophysical models, conducting research that spans from acquisition parameters to petrophysical properties, theoretical and experimental aspects of rock physics, and supporting the transitions from geo-modelling to geo-technical application. We also invite studies that focus on the characterisation of earthquakes, seismoacoustic or infrasonic sources, as well as methods to simulate wave propagation. This keyword also matches well to studies embedded in the recent KEM and DeepNL research programs.
The Earth sciences play a crucial role in many of the grand challenges our society faces. As a society, we need the resources of the earth (water, space, minerals, energy resources), but making use of the resources also affects the environment we live in. These effects add to the effects of natural processes of the system Earth such as earthquakes, floods and hurricanes. This keyword covers Earth scientific research and engineering with an explicit aim to apply science for the benefit of society. Societal impact occurs on different spatial and temporal scales: from for instance how processes in the Earth impact an individual farmer to their impact at the global scale.
Soils form the interface between the Earth’s crust and atmosphere and are a basis for life on Earth. Soils foster biodiversity and record the interactions between lithosphere, biosphere, hydrosphere and atmosphere. This keyword broadly covers the soil sciences as linked to a wide range of scientific and societal issues such as food security, water availability and climate change. It encompasses both fundamental and applied research, including the use of soils for geo-engineering purposes.
A vast majority of the Earth’s surface is covered by sedimentary deposits, which are eroded and deposited and form a direct link between the lithosphere, atmosphere, biosphere and hydrosphere. The sedimentary archive of Earth history is studied with a wide range of analytical techniques providing details on the evolution of our planet. Focused on all aspects of the sedimentary record, this keyword covers studies that will provide a better understanding of the physical, chemical and biological processes controlling the formation and distribution of sediments and sedimentary rocks.
Contributions for this keyword investigate rock deformation at all scales with the aim to understand its complex relationships using natural observations, including mapping, remote sensing and seismic measurements, and experimental approaches.
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.
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).
Most presentations at NAC will be in the format of a poster presentation, like on many of the international conferences in Earth Sciences. The poster prize aims to award early-career researchers (MSc, PhD, Postdoc) 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 another member of the Program Committee and a representative of the conference organisers. For competing in the poster prize you will need to sign up your poster in advance of the conference. Furthermore, it is required that you as first author are present at the closing ceremony on Friday. Read more about the assessment criteria and how to sign up for the poster prize.
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 2 December to 9 February. Please note that you must be registered for the conference before 9 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.
One of the photos will be used for the next year's website. The NAC 2021 home page features a photo taken by Els Ufkes (Free University, Amsterdam). The photo shows weathered dolerites & quiver trees (Mesosaur fossil bush camp, Spitzkop farm, Keetmanshoop, Namibia). Els remarks "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."
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 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.
