  1. ❗Update on Plagiarism and Falsification in Scientific Publications

    Today, I officially submitted requests for the retraction of articles to the editorial boards of the journals "Land Reclamation and Water Management" and "Bulletin of NUWM".

    ❗Key facts of misconduct:
    🔹 Plagiarism: Unauthorized use of my original relief map (2015) without citation.
    🔹 Falsification: Intentional removal (retouching) of the author’s stamp with coordinates and date-time on site photographs.
    🔹 Duplication: Publication of identical material in 2021 and 2024.

    Next steps:
    In the event of attempts to covertly remove the articles without an official retraction notice, relevant complaints will be forwarded directly to @crossref and the international members of the editorial boards.

  3. Defending a PhD in public is one of the stranger academic rituals. Mine's on YouTube now.

    The defence covers ML in geoscience: how neural networks can be applied to seismic data, what happens when you build physics into your architecture, and what I learned from four years of research.

    If you've ever wondered what a PhD defence actually looks like, here you go.

  4. ☀️ Albedo vs. Surface Temperature: Why a "Bright" City Isn't Always Cooler

    ❗ Key findings from the current stage of research:
    🔹 Vegetation (NDVI): Based on modeling results, biomass health accounted for approximately 40% of the variance in Calgary’s temperature regime in 2025.
    🔹 Albedo (Reflectance): While it is commonly assumed that high surface reflectance reduces heat absorption, satellite data (broadband shortwave albedo) reveals a far more nuanced picture.

    🔥 The Seton Anomaly
    The scatter plot clearly shows a wide distribution of values. The community of Seton is a particularly striking example: despite its high average albedo (likely due to light-colored soils at construction sites and new roofing materials), the area remains in a "heat zone" (classified as Warm Background in my model).

    ❗ Albedo plays a role, but it is not the dominant factor in Calgary’s environment.

  10. This fantastic interactive art piece from @bluerehn and Nellie Pease is on display at the South Australian Museum, or you can check it out online at chronovarium.com/.

    Chronovarium encourages you to change boundary conditions, see how the landscape changes, and then 'collect' your core.

    Here's mine - you can see the process from grassland to wooded area, to rainforest, to swamp, to jarrah forest, and the decisions I made along the way!

    Brilliant work Emma, and thanks for making it available online 💚

  16. When AI informs evacuation decisions, "it just works" is not good enough.

    I co-authored this piece on cultivating trust in AI for disaster management. We cover all four disaster phases -- mitigation, preparedness, response, recovery -- and where transparency around training data and failure modes is lagging behind deployment.

    If we want first responders to trust these tools, we have to earn it with openness.

  18. A ‘Waylaid' Teaching Diorama – USGS “Geology For Land Use”
    --
    For about 3 years, this gorgeous diorama has ‘just’ been sitting in a corner of a (common) hallway.
    I can’t help but wonder its history:
    • What prompted its creation?
    • Who was the artisan (truly!) that created it and used those components and focus?
    • When was it created? (late 1960s as an educated guess????)
    • Why was it seen as useful / in what setting? (as I am sure it was)
    • How was it funded?
    (never mind that I want to claim it for my office, space notwithstanding…)

  19. A slightly tongue-in-cheek AI animation of a conceptual model showing leakage of highly mineralized mine waters into a carbonate aquifer:
    youtu.be/WDIze8QNMYs

    Yes - it’s simplified. Yes - real systems are messier.
    But sometimes a "clean" visual helps to communicate density-driven flow and reactive processes more intuitively than 20 pages of equations.

    The animation idea emerged while working on my monograph. Draft versions are available here:

  20. Plate #tectonics represents a defining framework of modern #geoscience, accounting for large-scale features on Earth’s surface, such as mountains and valleys, as well as the processes that shape them, like volcanoes and earthquakes.

    Present-day plate tectonics have not been observed on any other world in the solar system, and evidence of past activity on planets such as #Mars and #Venus is circumstantial.

    Perhaps the best case for extraterrestrial plate tectonics is found in the floating ice shell of #Jupiter’s #moon #Europa.

    The plate tectonics on Europa differs from its Earthly analog. It is spatially widespread; it is regionally confined rather than globally connected; it occurs intermittently and is not happening now; and during past activity, plates drifted limited distances of between 10 and 100 kilometers.

  23. Result of a Principal Component Analysis (PCA) created from combined median composites of Sentinel-1 and Sentinel-2 imagery — somewhere in the Sudanese desert.

    This PCA composite brings out contrasts between lithologies, structural domains, drainage patterns, and surface materials, highlighting features that are nearly invisible in standard RGB representations.

    And yes — it also happens to look stunning.

  24. Exploring large-scale landscape structures with a simple Principal Component Analysis (PCA) applied to a MODIS composite.

    The PCA reveals striking contrasts in surface materials, vegetation patterns, and terrain transitions across western Canada — from the Rocky Mountains into the prairies and the Canadian Shield.
    Even with moderate-resolution MODIS data, spectral variability produces a surprisingly rich view of regional geography and geomorphology.

  25. Result of a Principal Component Analysis (PCA) based on combined median composites of Sentinel-1 and Sentinel-2 satellite imagery — somewhere in the desert of Sudan.

    The PCA highlights contrasts between different lithologies, structural domains, and surface materials, revealing subtle geological features that are hard to distinguish in standard RGB composites.

    And yes — it also looks simply beautiful.

  26. 🫐 The Blueberry Map Experiment — modelling meets the mountains

    In 2022, while living with my family in the Czech Republic, I built a digital map of wild blueberry hotspots in the Jizera Mountains.

    At first, it looked like a fun summer project — our neighbors used the map to find the best berry spots and enjoy the landscape.
    But behind it was a serious experiment: I tested species distribution modelling (SDM) methods, later adapted for wide-world rare earth element prediction.

    Within this “blueberry project” I:
    🔹 automated the full spatial workflow in R and QGIS,
    🔹 generated geomorphons and other terrain-based predictors,
    🔹 built and validated ML models,
    🔹 created probability maps and tested them in the field.

    ✨ What started as a family hobby became a field-tested workflow for predictive geoscience.

  27. 🚨 talk announcement! 🚨

    How does the geological record form?

    We can observe modern depositional environments using advanced remote sensing and direct sampling.
    We can observe geological strata through seismics, drillcores, and direct sampling.

    What happens in between?

    Xianyi Liu in my team is trying to find out, using the oldest known aerial photographs of the #Bahamas, and comparing them with today's facies distribution. It's a journey through #carbonate #sedimentology, #GIS, modelling and #MachineLearning. If you'd like a sneak peek, join his talk coming Tuesday at 17:00 CET at PaleoPERCS.

  28. Some more #work stuff.

    Getting an European Research Council (ERC) grant had this terrible outcome that I thought: now we can do in-depth, thoughtful research without cutting corners and ducktape solutions. Understanding #evolution in the #fossil record required a reproducible model representation of that record and we weren't satisfied with any of the existing models. Computer models made by (Earth) scientists are rarely very good, because we are not necessarily trained to make them, but to model events happening over hundreds of thousands of years, we crucially rely on their quality.

    So we decided to develop one. Thanks to its main developer Johan Hidding @eScienceCenter and the collaboration with Peter Burgess, Xianyi Liu and @Niklas_Hohmann we have a fast, sustainable, #OpenSource package in #julialang for modeling #carbonate platforms.

    The preprint is out for public review: please leave us a comment at egusphere.copernicus.org/prepr or try CarboKitten.jl at mindthegap-erc.github.io/Carbo
