U.S. allies warn that the Strait of Hormuz is still likely mined, casting doubt on Donald Trump's claim that the U.S. Navy has removed and detonated all explosives laid by Iran. https://www.japantimes.co.jp/news/2026/08/27/world/us-allies-hormuz-mined-trump/?utm_medium=Social&utm_source=mastodon #worldnews #mines #us #donaldtrump #middleeast #iran #straitofhormuz

Iran, Oman Seal Hormuz Corridor Deal as Trump Claims Mines Cleared

Tehran and Muscat finalize a joint shipping corridor and mine-clearing plan for the Strait of Hormuz, but Iran insists the waterway remains closed as a tanker is struck off Oman.

Un aspetto poco noto è quello della bonifica del sottosuolo, per la quale gli speleologi fanno il loro. Nell'aprile del 2024 vigili del fuoco, speleologi e militari della Birgata Pinerolo hanno provveduto a rimuovere e far brillare in luogo sicuro nove ordigni della seconda guerra mondiale inesplosi, estratti dalla Grave di Pasciuddo (PU40). Un ipogeo che scende fino a -150 m nel territorio di Cassano delle Murge (Puglia).

Quin un anno dopo, la grotta finalmente percorribile in sicurezza.

A lesser-known aspect is the cleanup of the underground, where cave explorers do their part. In April 2024, firefighters, speleologists, and soldiers from the Pinerolo Brigade removed and safely detonated nine unexploded World War II bombs extracted from the Grave di Pasciuddo (PU40)—a cave reaching a depth of -150 meters in the territory of Cassano delle Murge (Puglia).

Here, one year later, the cave can finally be explored safely.

“Winter roads are essential transportation links for many remote northern communities, but their safety and reliability depend strongly on snow conditions and ice growth. In this study [link above], [the authors] evaluated a fully polarimetric, dual-frequency Ku- and Ka-band radar approach for retrieving snow depth across landfast sea ice, lake ice, and tundra.
Using field measurements near Churchill, Manitoba, and Resolute Bay, Nunavut [Canada], [they] found that the approach produced snow-depth retrieval bias and error within 3 cm over landfast ice, with encouraging Ku-band performance over frozen ground as well. [They] also developed an interface-detection approach for lake ice that can retrieve both snow depth and ice thickness - a promising direction for characterizing conditions relevant to winter-road planning and safety…”

“Winter roads are lifelines for remote northern communities. Built over land, lakes, rivers, and sea ice, these travel routes are increasingly vulnerable to warming temperatures and variable precipitation. To ensure safety and adapt to these changes, operators require high-resolution monitoring of snow depth across these diverse surfaces, as natural snow accumulation dictates ice growth rates, route viability and road stability. This study extends our polarimetric radar method, previously demonstrated on pack ice, to landfast sea ice, tundra, and frozen lakes and assesses how well we can retrieve snow depth over these surfaces. Results indicate consistency with earlier sea ice analyses, maintaining a mean snow depth retrieval bias and error within 3 cm over the landfast ice. Promising performance is also found over frozen ground using Ku-band (mean biases less than 6 cm). To address the specific challenge of lake ice, which includes strong returns from the ice/water interface, we present a new interface-detection technique that simultaneously retrieves snow depth and ice thickness. While current validation focuses on undisturbed snow, this approach could provide a path forward for characterizing the cryospheric environment in a way that can directly support the optimization of winter roads…”

Four days to complete a hugely-improved record for 'Coflein', the Royal Commission's historic environment databse.

Very remote terrain and rarely visited, even in today's mass-tourism environment.

Nice to find an old stove and charred ground within the remains of an associated building.

Mountain hiking, with a purpose!

Finland, Germany, Denmark, Lithuania and Norway are purchasing potentially thousands of advanced sea #mines from a Finnish company Forcit.

The Blocker smart bottom mine is "probably the most advanced in the world" and already used by the Finnish and Estonian navies.

“A mouse never entrusts his life to only one hole”*…

… Well, our earth is riddled with them. And as our old friend Randall Munroe at xkcd reminds us, some of them are very deep…

“Holes”

Via Jason Kottke, who reminds us that “Explain xkcd has more info on each of the various holes, including the truly bonkers Cave of Crystals in Mexico” (and explanatory background on other xkcd posts as well…)

As we spelunk, we might recall that it was on this date in 1962 that the U.S. military detonated Little Feller I, a tactical nuclear weapon at the Nevada Test Site as part of Operation Sunbeam. It was the last near-ground atmospheric nuclear detonation conducted by the United States. The high-altitude Fishbowl tests concluded in November of1962 with a detonation at around 69,000 feet altitude. Thereafter, in accordance with the 1963 Partial Test Ban Treaty, tests were conducted underground… more holes.

"Quand il s'agit de béton, d'acier, de cuivre, de verre et d'aluminium, l'énergie renouvelable nécessite un ordre de grandeur de plus de matériaux par unité d'énergie électrique livrée que la combustion des combustibles fossiles. Ça se traduit par une exploitation minière, une fabrication, une pollution et tous les coûts écologiques associés qui ne s'arrêtent jamais. Ce n'est pas un projet où l'on construit une fois et c'est fini.
"L'énergie renouvelable n'est donc pas réellement renouvelable."

"Issues des exploitations minières impériales des colonies de peuplement à travers le monde, de certaines régions d'Australie et d'Afrique du Sud jusqu'en Californie, les #infrastructures d'énergies fossiles sont des promesses non tenues. Comme nous l'avons vu, une infrastructure est une promesse pour l'avenir. C'est un investissement financier, un placement de capitaux destiné à immobiliser des actifs liquides dans l'espace pour une durée dépassant le cadre d'une seule vie humaine. Mais c'est aussi un investissement social et imaginaire, un placement de nos espoirs d'une vie meilleure, non seulement pour nous-mêmes, mais aussi pour les générations futures. Or, les infrastructures construites pour extraire les énergies fossiles compromettent précisément l'avenir qu'elles sont censées ouvrir. Le déversement massif des réserves de carbone souterraines dans l'atmosphère a érodé l'infrastructure la plus cruciale de toutes : la Terre elle-même."
