Update: an article here confirms plate tectonics 1.1-1.3 B yrs. ago, where plate movements helped concentrate the iron ore.
By the way, "exhuming my thesis" was an inside joke: the geology and tectonics both in my area in N Ontario and the inspiration paper in Alaska talked about "exhumed terranes"; continental blocks that were buried and metamorphosed, displaced and then exhumed back to the surface to their current location.
Update: note a dash of AI mixed in at the bottom for fun
Our TV rung in 2025 live in Paris in my time zone, and six hours later in NYC dropping its ball in Times Square; nothing matches however this cracking event in London to usher in the New Millennium: barges were aligned in the middle of the River Thames, spaced exactly 1 s. apart as the earth rotated past midnight GMT in London, from the Meridian at the Millennium Dome to the east, to Vauxhall Bridge to the west.
Update: see here papers a decade later that point also to precambrian terranes.
My 1982 M.Sc. thesis, Regional cross section of the Southern Province adjacent to Lake Huron, Ontario: implications for the tectonic significance of the Murray Fault Zone (ResearchGate) proposed a plate-tectonic (Wikipedia) setting around 1.9 billion years ago, in the Proterozoic (late Pre-Cambrian). I presumed there was another buried land mass south of what I called the Manitoulin Island Discontinuity. While plate tectonics was well established in the later Phanerozoic (Wikipedia) record, it took a lot longer to be accepted earlier in the geologic time scale with lot scanter rock record to go by (more at the bottom).
Five friends at Arts & Metiers engineering school in Paris took a ten month leave to sail around the North Atlantic: Lez'Arts Marins (here) sail south from Britanny past the Azores & Madeira to Senegal for a moth humanitarian aid project, west across to Martinique and northeast N of Scotland to Scandinavia and back.
An update to a Northwest Passage blogpost posted to the Facebook Rememberig Frankline Expedition group, elicited a response from @aaron.spitzer. I post his comment below, which I thanked him for citing the fact my stories were from conversations that weren't fact-checked. That in turn got me to fact-check another story from the same 1986 summer in the Arctic Islands from my now-defunct original website reposted at bottom.
Almost four years ago, a story map here showed the Skelworth Fold area of the Lake District for a friend, using advanced mapping and Environment Agency digital elevation.
Update: the last of a series, follow my recap blog post here incl. Medium Channel posts on AI.
Note: the last post on my personal Medium channel shows how I used Copilot AI to good effect for fact-checking.
Last we showed here how to create "quick & dirty" graphs while chatting on ur mobile. Now we'll see how we can create summaries, not from "text to hand", but from that cribbed off the internet.
Having left socials, I'm down to corresponding at Extinction Rebellion "Media Tell the Truth" WhatsApp group. Jon Fuller there is also at "Climate Genocide Act Now" here. I was a scientist for Extinction Rebellion, and blogged here about the pandemic against the lies of the British government, as well as about floods and rising sea levels in East Anglia. I didn't know GCAN, however, as I'm no longer active.
Update: Part VII here follows w using ChatGPT to summarize off the web direct.
Part V (here) showed elaborate (mis)use of AI. Here is a super simple example whipped up in Google Gemini on the phone during a chat about value change over time. Notice all along, adding less & less detail shows AI perists previous prompts.
Update 2: see here an update on Beechey Isl. site discovered the year before my visit below
Update 1: right on cue, a photo exhibit on Arctic Life and Climate Change in Budapest HU on Euronews.
Here is an old webpage from 1996 I had to retire a couple years ago. It smacks of urban legend, had I not been told by airport staff in Resolute on Cornwallis Isl., the Arctic Canadian hub (read on):
Update: see @ bottom example of a Cyclone (Wikipedia) as they're called in the So. Hemisphere.
Further to our explorations in AI here and to the previous post here, this is a 'conversation' with Copilot, Microsoft Bing's AI extension. Conversation means that you can daisy-chain questions without repeating them, either to extend or to zero in:
