Keynote:Faulty Communications – conveying contested geoscience to the public by Iain Stewart
Geoscientific knowledge and understanding lies at the heart of many of the most critical societal issues that face us in the 21st century. The pressing human challenges of natural disaster reduction, energy supply and security, and mineral and water resource management, rest on geological foundations. And yet, outside of the academic and industrial geoscience community there is a limited appreciation of Earth Science, especially among policy makers. Geology , it seems, lies out of sight and out of mind. For that reason, geologists are increasingly being encouraged to communicate more broadly what they do and what they know. Yet how can we do that when, for most people, geology is about 'stones' and stones are 'boring'! It is a problem compounded by the fact that many of our most acute geo-issues are rooted in the unfamiliar realm of the deep subsurface. This talk will use the experience of popularising geoscience for mainstream television to explore ways in which geologists can make our research connect better with the dissonant public, and in doing so forge more effective strategies for meaningful public engagement.

Iain is professor of Geoscience Communication at Plymouth University and Director of its Sustainable Earth Institute. His long-standing research interests are in interdisciplinary investigations of geological hazards (earthquakes, volcanism, tsunamis) and abrupt environmental change, and more recently in the communication of ‘contested geoscience’ to the public. As part of his geo-communication he regularly presents Earth science programmes for BBC television, including Earth: The Power of the Planet; How Earth Made Us, How To Grow A Planet, The Rise of the Continents and Planet Oil.
Lecture:Masterplan Jakarta by Nikeh Booister
nikehJakarta is one of the biggest delta cities in the world; with in the metropolitan area about 29 million people. The urban area is a complex system which also in Jakarta causes a lot of problems. One of them is flooding, which is strongly related to land subsidence. Every year parts of Jakarta flood and this problem becomes bigger every year. To protect the city against flooding the NCICD plan has been designed; a plan that is divided into three phases; A) strengthening the current sea wall (under construction), B) constructing an offshore seawall & creating a retention lake for Western Jakarta and C) protecting Eastern Jakarta with a sea wall and retention lake.

Nikéh is consultant Water Management and Hydrology at Sweco and works for national and international projects around water management, flood risk management and climate change adaptation. Before working at Sweco Nikéh studied Water Management and a Erasmus Mundus Master in Flood Risk Management. For Sweco she works on projects like the STAR-FLOOD project, smaller SOBEK modelling projects, statistics and calculations of the IJsselmeer water level project (Delta programme) and the National Capital Integrated Coastal Defence (NCICD) project in Jakarta.
Lecture:ExoMars Mission by Jorge Vago
JorgeVago_410The first ExoMars mission was launched on 14 March 2016 and arrived at the red planet on 19 October 2016. It incudes two elements: 1) the Trace Gas Orbiter (TGO) to study atmospheric trace gases and subsurface water with the goal to acquire information on possible on-going biological or hydrothermal rock alteration processes; and 2) Schiaparelli, a European Entry, Descent, and landing Demonstrator Module (EDM) to prove technologies for controlled landing and perform measurements during descent and on the martian surface. Unfortunately the last phase of the EDL sequence did not work and the lander was lost. TGO will also provide data communication services for surface missions, nominally, until end 2022.

The second ExoMars mission is scheduled to launch on 24 July 2020. It will deliver a 310-kg mass rover and an instrumented landed platform to the martian surface. The rover will explore the landing site’s geological environment and conduct a search for signs of past and present life. A drill will allow the rover to collect and analyse samples from outcrops and at depth. The subsurface sampling capability will provide the best chance yet to access and analyse well-preserved sedimentary deposits, possibly containing molecular biosignatures.

The rover’s Pasteur payload includes: panoramic instruments (wide-angle and high-resolution cameras, an infrared spectrometer, a ground-penetrating radar, and a neutron detector); a subsurface drill capable of reaching a depth of 2 m to acquire specimens; contact instruments for studying rocks and collected samples (a close-up imager and an infrared spectrometer in the drill head); a Sample Preparation and Distribution System (SPDS); and the analytical laboratory, the latter including a visual and infrared imaging spectrometer, a Raman spectrometer, and a Laser-Desorption, Thermal-Volatilisation, Derivatisation, Gas Chromatograph Mass Spectrometer (LD + Der-TV GCMS). The very powerful combination of mobility with the ability to access subsurface locations is unique to this mission.
After the Rover will have egressed, the Platform will carry out scientific environmental measurements at the landing site.

This presentation will discuss both missions, but concentrate more on the ExoMars rover.
Lecture:Groningen Gasfield by Wim Moelker
13abb28The extraction of natural gas has brought much prosperity in the Netherlands throughout recent decades. But, there is also a negative side to this story. Nowadays, the extraction of gas from the Groningen gas field in the northern Netherlands can induce earthquakes. These man-induced earthquakes can cause damage to buildings and have lead to the feeling of insecurity amongst residents.

Wim Moelker, NAM Project Manager, is one of our guest speakers at the Earth Science Career Event in 2017. Throughout his career, he has worked in Iraq, Libya, Oman, Nigeria and Schoonebeek. His lecture focusses on the extraction of natural gas, positive and negative consequences of this mining for the Netherlands, the province of Groningen and the residents in the affected region. In addition, he will speak about the reinforcement projects by the National Coordinator Groningen, as well as the career opportunities that lie within NAM or multinationals such as Shell (one of the shareholders of the NAM).
Lecture:Port of Rotterdam by Janneke de Graaf
The Port of Rotterdam NV is planning to deepen the Nieuwe Waterweg and the harbours Botlek and Vondelingenplaat to improve nautical accessibility. Such an extensive river improvement plan requires authorisation of the ‘Ontgrondingswet’ (OW) – (earth removal permit). Decision making on granting this permit requires an Environmental Effects Report (MER).

With regard to the Rijn-Maas estuary salination has always been a major issue. Therefore the effects of the deepening (just the deepening, or deepening combined with other planned initiatives) are indicated in the MER. It reviews the effects on salt infiltration in the main water system and the regional water systems that are affected by this, inclusive of the effects derived on user functions and possible mitigating measurements. Besides the effects of salt infiltration other sub studies, such as morphology, are executed in the MER.

Main focus is on:
- Insight in a possible increase of the frequency and duration of the suspension of water supply to the rural hinterland
- Insight in an increase of the content of chloride

Based on previous research HydroLogic has executed an analysis of the sweet-salt system in the Rijn-Maas estuary. The effects of the deepening are quantified with 3D and 1D models and have been discussed with the stakeholders. The research has resulted in insight in the impact of the deepening on the water availability in the Rijn-Maas estuary.
