Why Earth’s Poles Could SHIFT in Our Lifetime

The invisible shield that protects all life on Earth is changing. The magnetic north pole has abandoned Canada and is racing toward Siberia at speeds never recorded in human history.

We will be hosting the 10th International #Conference on Rayleigh-Bénard #Turbulence in #Lyon (1-5 June 2026) !
Abstract submissions are now opened.

The aim of the conference is to bring together researchers from different fields to explore the latest advancements in high Rayleigh number #convection. A full day will review critical connections between #turbulent #thermal #convection and #geophysical processes.

I do terrestrial #archaeology, but for 24 years I also processed & analyzed offshore #geophysical data like this magnetometer data. I analyzed the data & compared it to known existing infrastructure, figuring out which linear feature is what pipeline, what blob was what well, etc.

I tried to train an assistant two times. In both cases they decided they didn't have the patience to do it.

5g magnetic contour data along a proposed pipeline route in the Gulf of Mexico a few years ago displayed as a repeating rainbow palette (left) & as a fuchsia to blue rainbow scheme (right). The repeating colors are better to show complexity, while the single rainbow shows highs & lows. #Archaeology #Geophysical

Two major #scientific societies will try to fill the void from the Trump administration’s dismissal of #scientists writing a cornerstone federal report on what #climate change is doing to the #UnitedStates. American #Meteorological Society & American #Geophysical Union will work 2gether 2 produce peer-reviewed research documents assessing current, future national impacts of #climatechange. #Trump #GOP #maga ended the work of 400 scientists on National Climate Assessment https://apnews.com/article/climate-change-trump-firing-report-damage-a76d2e2d3dfec7318b124b05a78d1ee1

In a time when science resources are being suppressed or deleted, I'm glad to see this film is still online (if a bit hard to discover - it's not even linked from the page below, you'll have to poke around a bit to find the link to the directory containing the zipped file).

I was honored to meet with Dr. Untersteiner and work with him on this project. I had nothing to do with the silent film footage, but decades after it was filmed he hired me to move forward with his vision of having a narrated version of it.

In addition to helping produce this version of the film, I got to know enough about Dr. Untersteiner personally that I'm sure I would have enjoyed knowing him longer. We did not stay in touch, though, and he passed away a few years later.

(I own no rights to the film, otherwise I might remaster it and find a more convenient place to host it.)

How can undersea mud and sand avalanches be tracked? They wash away the measuring instruments in their path!

A research team including our Uni and led by Durham Uni used earthquake sensors to measure sediment flows from a safe distance: https://www.uni-goettingen.de/en/3240.html?id=7681

Side scan sonar in the northern Gulf of Mexico showing schools of fish. A few of the fish are represented by dark dots, with the majority seen as short to long shadows (white) depending on how high they were in the water column.

Why tag archaeology? We have to evaluate every sonar contact to determine whether it is or potentially is a shipwreck, modern debris, natural feature or plant/animal so the government reviewer doesn't say, "You missed something."

I'm building a lightweight, low power, waterproof, #multisensor, configurable #magnetometer for #geophysics and #geophysical site investigation. Logging with low power Linux SBC (Pi/Pocketbeagle). Interested in helping fund the project for discount prototypes? DM me. 10,000-250,000 nanoTesla sensitivity range less than 1kilo per meter of array. Maybe less. Easily flown with a drone, your choice of GPS.
