The safe, efficient and cost-effective use of the subsurface for the exploration and exploitation of natural resources and the construction of transport and storage infrastructures require a thorough knowledge of the geological and geophysical heterogeneity. Projects dealing with geothermal energy production, CO2 storage, groundwater extraction, hydrocarbons exploitation and subsurface infrastructures all depend on reliable static and dynamic computer models to assess the economic, safety and environmental risks. The models should adequately describe the subsurface architecture in combination with the heterogeneity of relevant rock properties enabling proper simulations.
We invite contributions on case studies and innovative approaches to construct static earth models based on, e.g., process-based numerical forward modeling, 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.
Presentations on studies and proposals related to the recent KEM and DeepNL research programs are especially welcomed.

The session welcomes geological, geomorphological, pedological and botanical work carried out in archaeological context, applied and academic.

Monitoring, modelling and prediction are basic issues in hydrology and geohydrology. In this theme we invite contributions that pay attention to the 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 may also include research in reservoir engineering, civil engineering, soil sciences en environmental sciences.

In this session we would like to highlight recent advances in Dutch Planetary Geosciences, including geological, morphological, geophysical, astronomical and geochemical studies of planet- and moon interiors, surfaces, and atmospheres. This includes remote sensing based studies, numerical and analogue modelling studies, extra-terrestrial sample analysis, and terrestrial analogue studies.

Earth sciences, not in the least through the availability of ever more Earth observation satellite data, like from the European Copernicus Sentinel satellite program, but also the increasing capabilities of drones and (often commercial) small-sat constellations This theme will focus on exchanging information on the use of Earth observation and the best practices and available tools for Earth science applications, including upcoming BigData/BigScience issues. Abstracts are invited in all Earth science fields including solid earth, geology, geomorphology, oceanography, atmosphere science, air-quality, glaciology, soil sciences, ecology, vegetation, land surface, hazards, climate, safety & security, and natural resources.

Under the Solid Earth theme we solicit contributions on the structure, properties and dynamics of the Solid Earth and its constituent materials. The anticipated scope ranges from the core to the Earth’s surface and includes the effect of deep processes on (near-)surface evolution and their role in the context of System Earth. Studies on the coupling of solid earth geophysical phenomena to the ocean and atmosphere, and vice verse, are welcomed. We also welcome Solid Earth contributions to studies of geohazards and energy resources.

All contributions related to biogeochemical cycling are welcome in this theme. The (microbial) ecology of elemental cycles in modern ecosystems (terrestrial and marine) as well as studies that relate biogeochemical cycling to past environmental change, including reconstructions of abrupt changes and their impact on biota over long time scales, are of special interest.

In this theme we invite contributions in the area of paleoclimatology based on reconstructions using marine, terrestrial and ice archives as well as model studies offering understanding of individual processes, thresholds and tipping points. In particular studies focusing on the feedbacks, between the various components of the Earth system are encouraged. Furthermore, we invite contributions on model-data comparison in paleoclimatology.

We welcome contributions dealing with biosphere-geosphere interactions in the past and in the future, and research at the interface of (micro)biology and earth sciences. The development and calibration of proxies and their use to reconstruct paleoenvironments from the Precambrian to the Anthropocene are of special interest.

We invite contributions on sedimentary processes and products in terrestrial, coastal, and marine clastic and carbonate settings. Ongoing processes, young sedimentary records, ancient outcrop studies, numerical and analogue modeling efforts are all welcome. Contributions that integrate the sedimentary and geomorphological records with (paleo-)biological and (paleo-)climatic data sets are welcomed too. Returning issues have been physical genesis of landforms and sedimentary rocks, their age, their heterogeneity in composition and structure, the controls on their formation and their preservation, postdepositional processes such as compaction -- and the relevance of this all in applied contexts.

No life without soil. Soils foster above and below surface biodiversity and record the interaction between lithosphere, biosphere, hydrosphere and  atmosphere. Today's soils link to a wide range of societal issues such as food security, water availability and climate change. We welcome all soil science contributions, and particularly encourage you to present research relating soil science with climate change mitigation and adaptation.

This session covers research topics on atmosphere (e.g., numerical weather prediction, clouds, boundary-layer meteorology, air quality, weather extremes), ocean (e.g. large-scale circulation, coastal oceanography, sea level change), cryosphere (land/sea ice mass balance) separately, or on interactions between these three components of the climate system. We welcome contributions on theory, observation and modelling.

This session welcomes contributions in the field of modern ecology, flora and fauna, 
and vegetation science in relation to geomorphological and geological science.

In this session we welcome any contributions on research performed within the Netherlands Earth System Science Center, an NWO Gravity program funded by the Ministry of Education, Culture and Science. A selection of the contributions will be presented at a dedicated NESSC parallel session at the NAC, another selection of contributions will be presented at the NESSC day which is preceding the NAC, while the remaining contributions will be presented as posters on the NESSC day as well as the NAC.

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. We invite contributions that, in some way or another, respond to such trends and (may) result in enhanced teaching and learning. We are interested in best practices (e.g., new courses, innovative IT applications, examples of interdisciplinary student projects, etc.), as well as innovative ideas and suggestions for future improvements (e.g., serious games, ideas for strengthened career orientation, proposals for structured mobility, etc.).

Land subsidence may have potentially catastrophic consequences, particularly in densely populated low-land areas, like the Netherlands. It results from the interplay of different processes ranging from drainage of shallow clay and peat deposits, extraction of groundwater or hydrocarbons from deeper-seated reservoirs, to large-scale tectonic movements.

We particularly welcome contributions on the physical and chemical processes causing subsidence, and on methodologies to predict and monitor subsidence in time scales relevant to mankind.
