Department of Hydrology - GEUS’ Post

My commentary discussing recent advances into our understanding of Earth’s core-mantle boundary is out in Nature Geoscience! The most significant discontinuity within Earth demands detailed investigations, and here I discuss some of the novel methods to do so. I am excited about the forthcoming discoveries about this region!

Geology encompasses all of the Earth sciences and thus is multidisciplinary. It does not respect geopolitical borders, so it requires teamwork across disciplines and between nations. Applying geological solutions to climate change increasingly requires transdisciplinary teamwork. This extends well beyond the geosciences to inform on issues of universal concern, e.g., deployment of renewable energy, management of groundwater resources, mitigation of climate-induced geohazards, and more. To achieve sustainability and success in these fields, it is essential to employ knowledge of subsurface, land, and subsea geology for the discovery, tracking, preservation, regulation, and exploitation of resources. This knowledge also supports integrated and coherent surface and subsurface spatial planning and the creation of cohesive laws guided by scientific insights. This in turn requires multi-stakeholder collaboration between scientific and governmental agencies, industry, and civil society, from research design to data and knowledge application. Such a broad spectrum of engagement is at the heart of the concept of a Geological Service for Europe, founded on a long history of collaboration between the Geological Surveys of Europe –extending networks, fostering innovation, sharing knowledge, building capacity and common standards. Given the current lack of public knowledge and negative perceptions of geology, collaborative efforts based on objective science can have a significant impact on building trust. This contribution highlights the collaboration of the Geological Surveys of Europe with non-geoscientific partners in serving society, supporting nature, and delivering the Green Deal.

UNLOCKING THE EARTH'S LOWERMOST MANTLE Lauren Waszek has published a new commentary on the #Earth's core-mantle boundary—the most extreme boundary within the Earth (including the Earth's surface). I am happy to see her discussing the importance of multidisciplinary approaches in this field of study. Besides global #seismology, related fields of studies like #geodynamics, #mineral #physics, and #mathematical #geophysics come to mind, to mention only a few. I recommend reading her commentary to the Earth's interior enthusiasts. Some of our #tomography work on the lowermost #mantle has been mentioned in the context of extracting more information from the existing data. Indeed, we have most recently shown how to image multi-scale #heterogeneity with #shear waves sensitive to the lowermost mantle (Mousavi et al., 2021), #compressional waves sensitive to the lowermost mantle structure and topography (Muir et al., 2022), and even within the so-called ultra-low-velocity zones (Pachhai et al., 2022), all accompanied by an assessment of #uncertainty. Along with increasing the computational power and volumetric coverage of the Earth by #seismic #waves and the sheer volume of waveform data, extracting information from the existing data is one way forward in the Studies of the Earth's Deep Interior (SEDI). Expect more contributions soon.

Reminder about this presentation tonight it should be a good one!

Vey excited to have an international presentation with an Alaskan perspective on groundwater next month! Please see the details in the post below on what is sure to be a interesting and informative presentation from Geoffrey Coble

I have just attended the event '𝗖𝗶𝘁𝗶𝗲𝘀 𝘂𝗻𝗱𝗲𝗿 𝗽𝗿𝗲𝘀𝘀𝘂𝗿𝗲: 𝗔 𝗗𝗲𝗲𝗽 𝗗𝗶𝘃𝗲 𝗶𝗻𝘁𝗼 𝗨𝗿𝗯𝗮𝗻 𝗚𝗲𝗼𝗹𝗼𝗴𝘆 𝗮𝗻𝗱 𝗖𝗹𝗶𝗺𝗮𝘁𝗲 𝗜𝗺𝗽𝗮𝗰𝘁' organised by the GSEU - Geological Service for Europe at the Royal Belgian Institute of Natural Sciences. There was a screening of the interesting documentary '𝗧𝗵𝗲 𝗨𝗿𝗯𝗮𝗻 𝗚𝗲𝗼-𝗖𝗹𝗶𝗺𝗮𝘁𝗲 𝗙𝗼𝗼𝘁𝗽𝗿𝗶𝗻𝘁' (https://lnkd.in/dA7Pnvhi) on how the geology beneath cities affects their resilience to climate change. The documentary zooms in on several European cities and highlights the impact of geology, exogenous, surface and subsurface events and human activities on the resilience, threats and opportunities in our urban centres. The documentary was followed by a quiz, which yours truly won, so I'm now the very happy owner of a 𝗡𝗼𝗿𝘁𝗵 𝗦𝗲𝗮 𝗖𝗼𝗿𝗲 𝗱𝗿𝗶𝗹𝗹𝗲𝗱 𝗶𝗻 𝟭𝟵𝟵𝟮 😍. This trophy, along with the Tony's Chocolonely chocolates, will be proudly displayed in the TRAQUA office tomorrow. The event also presented the new tool '𝗨𝗿𝗯𝗮𝗻 𝗚𝗲𝗼-𝗰𝗹𝗶𝗺𝗮𝘁𝗲 𝗙𝗼𝗼𝘁𝗽𝗿𝗶𝗻𝘁 (𝗨𝗚𝗙)', developed by the Italian Geological Survey ISPRA in collaboration with several colleagues from the Urban Geology Expert Group of EuroGeoSurveys (https://lnkd.in/df8_PZ5E). The aim is to provide a geological fact sheet: an overview of the main characteristics, potential risks and opportunities related to the geology of each city.
