Canada will buy six Saab GlobalEye early-warning aircraft (based on Bombardier Global 6500) over Boeing’s E-7 Wedgetail, aiming to reduce reliance on US defense suppliers. Saab pledges Canadian R&D investment, underscoring closer Canada–Sweden ties and Arctic defense autonomy, while Ottawa continues its F-35 program with Lockheed Martin.
A bipartisan, all-women Senate delegation led by Sen. Jeanne Shaheen (D-N.H.) and Sen. Lisa Murkowski (R-Alaska) travels to the Arctic to reaffirm the United States’ commitments to its partners in the region.
Trump’s handpicked Greenland envoy Jeff Landry erupted on camera during an unofficial Nuuk visit, declaring that Greenland was “not on the map” until Trump put it there, and pressed reporters while inserting himself into meetings. Greenland and Denmark have rejected annexation or sale and stressed Greenlandic self-determination. The frosty reception and reports that Landry invited himself to events underscore tensions over the Arctic and U.S. security aims, with no hospital ships deployed and ongoing pushback from Greenland’s government.
Greenland's Prime Minister Nielsen reaffirmed the territory's right to self-determination in a meeting with a U.S. envoy linked to Trump, signaling a continued push for greater autonomy though no referendum was announced.
DNA from living descendants identified four Erebus crew members and the sole Terror sailor among the remains from Franklin’s 1845 expedition, solving long-standing misidentifications and offering clues about why the crew deserted their ships. The study by researchers at the University of Waterloo and Lakehead University used Y-chromosome and mitochondrial DNA to match bones to relatives, building on earlier identifications of John Gregory and James Fitzjames, with ongoing efforts to name more crew and humanize the tragedy.
NASA’s Curiosity rover encountered an unusual hitch when a rock named Atacama stuck to its drill sleeve during a Mars sampling attempt, but ground teams freed it after several maneuvers; in Greenland’s Inglefield Bredning, researchers deployed a deep-water camera and hydrophone at 260 meters to document 478 organisms and sounds (including narwhals and iceberg activity), showing a feasible approach for Arctic seafloor studies; NASA also released thousands of Artemis II mission photos featuring lunar, Earth, and Milky Way views.
NOAA-backed research reveals the Denmark Strait cataract, an underwater waterfall beneath the Arctic between Iceland and Greenland, draining cold Nordic Sea water downward at about 3.2 million cubic meters per second (≈123 million cubic feet per second). It’s the world’s largest waterfall by volume, though invisible to ships, and it helps drive the Atlantic Meridional Overturning Circulation, influencing Europe’s climate and marine ecosystems. Warming could weaken or alter this flow, with potential global climate implications.
Iceland has recorded its first mosquitoes (Culiseta annulata), underscoring rapid Arctic ecological shifts driven by warming and human activity. Researchers warn that the Arctic’s changing arthropod communities could ripple through ecosystems and climate feedbacks, but long-term, standardized monitoring remains underdeveloped. They advocate an international, coordinated arthropod monitoring network (Network for Arthropods in the Tundra) to track movements and determine whether new arrivals persist across the Arctic.
Scientists using MBARI surveys found that submarine permafrost beneath the Canadian Beaufort Sea is actively forming ice and melting due to geothermal heat, creating rising mounds and fresh craters in the seafloor and revealing that Arctic submarine permafrost is not ancient or static, a finding with implications for infrastructure and methane risk in the region.
A Nature Communications study using computer simulations projects that by 2060 polar cod could struggle to find adequate food in a warming Arctic, as earlier spring sunlight boosts prey while higher temperatures raise energy needs, risking poorer winter fattening and threatening a keystone species vital for predators across the Arctic; capelin may not fully compensate, and fish are already shifting north, underscoring broader ecosystem risks.
Three Trump allies openly pursuing business and policy in Greenland—Drew Horn’s data-center project, Thomas Dans’s Arctic outreach and government role, and Chris Cox’s pro-Trump campaigning—have drawn Danish scrutiny as Denmark summoned a U.S. diplomat; the episode underscores how Trump associates blend business and policy in Greenland amid rising Arctic interest.
Arctic sea ice reached its winter maximum at about 5.52 million square miles, roughly tying the lowest on record and about 525,000 square miles below the 1981-2010 winter average, signaling a steady decline as warming continues. The smaller ice pack means less sunlight reflected, allowing more heat to enter the oceans and potentially affect the summer melt and weather patterns. Antarctica meanwhile posted its coldest March day on record; melting sea ice does not raise sea levels, but the broader loss signals climate disruption with implications for ecosystems and shipping routes.
Danish broadcaster DR reports Denmark secretly deployed troops to Greenland in January with explosives and medical supplies as a contingency against a potential US invasion, part of a NATO Arctic Endurance exercise that included allies France, Germany and Sweden; the plan was detailed in an operations order, while Danish and Greenlandic leaders reportedly resisted Donald Trump’s push to acquire Greenland, and NORTHCOM later signaled expanded access to Greenland bases.
Denmark reportedly prepared to blow up Greenland airstrips in Nuuk and Kangerlussuaq to deny access to potential US forces in a worst-case scenario, as European allies rushed troops and resources (including armed F-35s and blood supplies) to the Arctic; the episode followed heightened US pressure to seize Greenland and a political turning point after a US operation in Venezuela, with PM Mette Frederiksen later saying Europe is Denmark’s closer ally and calling a snap election for March 24.
DR reports that a January Danish-led Greenland deployment, part of Operation Arctic Endurance and including troops from France, Germany, Norway, and Sweden, was prepared to destroy key runways at Nuuk and Kangerlussuaq to prevent a US invasion amid Donald Trump’s Greenland ambitions; the claim, backed by multiple Danish and European sources, comes as Copenhagen sought European support, while the Danish defence ministry declined to comment.
