Along coastlines, where tides are typically magnified, they profoundly affect navigation, commerce, coastal flooding, water properties and sediment transport. Tides impact the flooding of rivers and, thus, influence the extent of their floodplain, which has cascading effects on biogeochemical and ecological processes.
Signals from Global Navigation Satellite Systems are quite vulnerable. They are exceptionally weak, meaning that any radio noise near their frequency, accidental or malicious, can interfere with reception. I am confident that there are people in every government who understand the problem. The challenge is getting leadership to both understand and act to reduce the risk.
In the two weeks since the U.S. and Israel launched attacks against Iran, thousands of vessels have experienced navigation interference in the Persian Gulf. Commercial shipping through the strait, which carries roughly 20 percent of the world's oil, has nearly ground to a halt. Though rocket and drone attacks are also to blame, another major hazard is GPS spoofing—the transmission of counterfeit satellite navigation signals.
Long-range radio waves can pass through obstacles more easily, which makes them perfect for monitoring expansive factories or outdoor infrastructure. A recent report by Fabrity highlighted that these systems use very little power. This allows sensors to operate for 5 to 10 years on a single battery. Using such tech means you do not have to install expensive wiring across your entire site.
Apple's satellite features were originally designed for emergencies, allowing iPhone users to contact emergency services when cellular and Wi-Fi coverage is unavailable. With recent versions of iOS, Apple has expanded those capabilities to include sending and receiving messages via satellite. This makes it possible to stay in touch with friends and family from remote locations where traditional networks do not reach, such as hiking trails, rural areas or offshore locations.
Garmin has launched the Quatix 8 Pro nautical smartwatch with built-in inReach support, adding satellite and LTE-based communication to its marine-focused wearable lineup. The smartwatch is aimed at users who spend long periods on the water and need communication, navigation, safety, and vessel control features without depending on a smartphone. It supports two-way messaging, voice calling, SOS alerts, and marine controls, while also offering full smartwatch, health, and fitness tracking when used on land.
The Royal Navy said on Friday that they have launched a new full size crewless helicopter which is designed to track submarines and will undertake missions in the North Atlantic. Since Vladimir Putin launched a full-scale war in Ukraine the defence industry has been remodelled as most European government's have increased military spending. The helicopter named "Proteus" has completed a test flight and was part of a £60 million programme,
U.S. defense planning rests on the assumption that wars are fought abroad, by expeditionary forces, against defined adversaries. For decades, those assumptions held. But today, many of the most consequential security challenges facing the United States violate all three. They occur closer to home, below the threshold of armed conflict, and in domains where sovereignty is enforced incrementally. The shift has exposed a chronic mismatch between how the United States defines its defense priorities and how it allocates resources and respect.
If you've never docked a boat before, consider yourself lucky. There are plenty of popular TikTok channels devoted to shaming those who bring their craft back home clumsily or berth them with something less than finesse. Tricky crosswinds, unpredictable surf and even the jeers of passersby can make it a stressful experience at the best of times. Brunswick, which owns more than 50 water-borne brands like Sea Ray, Bayliner and Mercury Marine, has a solution.
NMSurf is one of the largest fixed wireless providers in New Mexico, serving the central and northern area of the state. La Bajada was previously served by a 3-Gig microwave middle-mile connection. But, Catanach said, the bandwidth was becoming insufficient. New microwave licenses are hard to come by in New Mexico, he added, because the state itself claims many licenses for radio communications.
The other day we were scrolling through r/meshtastic and someone asks: "Why does my device show 10+ satellites in view while my buddy's barely sees 8?" Good question. Really good question, actually. And it's about to take us down a rabbit hole that involves atomic clocks, Cold War competition, European independence, and why your Meshtastic node cares about all of this.
Wave Browser is working to reverse that equation. With a unique new partnership with 4ocean, Wave Browser connects your browsing to mitigating environmental impact: every session helps fund the removal of plastic and other waste from our ocean, rivers, and coastlines around the world. Every time you surf the web, Wave Browser contributes to 4ocean's cleanup projects that focus on waterways across the globe, from the United States to the Dominican Republic, and Indonesia.
We will be trekking the eastern part of the Great Himalaya Trail in Nepal in March/April. Details on the route and our plans can be found at https://greathimalayatrail.de. Our intent is to keep friends and family updated on our progress. Given that we'll be hiking in quite remote areas, a satellite phone/pager will be our sole means of communication. After the Garmin inReach Mini 3 was released recently, the Inreach Mini 2 was on heavy sale.
In this photo, I'm preparing drifting buoys for deployment. This was my main responsibility aboard the RV Falkor (too), during a 27-day research expedition in October 2025 exploring the Malvinas Current, an ocean current that runs alongside Argentina. The expedition included biologists, geologists and physical oceanographers such as myself; I'm a PhD candidate at the Sea and Atmosphere Research Center (CIMA) in Buenos Aires, Argentina.
