Ocean science under pressure: The US plans to “descop[e]” and remove more than 900 deep-sea instruments from the $368M Ocean Observatories Initiative, including arrays in waters off Oregon, Washington, Alaska, North Carolina and the Irminger Sea near Greenland. Supporters say the data are vital for tracking greenhouse-gas uptake, marine heat waves and the Atlantic Meridional Overturning Circulation (AMOC); NSF says it’s not a full cancellation, but a shift to a “nimbler” approach. Arctic eclipse watch: A total solar eclipse on Aug 12 will pass through Arctic regions and cross Greenland, with just over 2 minutes of totality there; ESA will stream it live. GPS disruption: A new study says Russian satellites have caused brief GPS signal disruptions across Europe, Greenland and Canada since 2019. Greenland rare earth momentum: Greenland Mines says it moved fast on-the-ground after signing to acquire the Sarfartoq rare-earth project, aiming to build supply chains outside China. EU tech sovereignty: The European Commission pushes chips, cloud/AI and open-source plans to cut reliance on US and Chinese suppliers, while the European Parliament switches its default search engine to France’s Qwant. Narwhal research with Inuit hunters: In northwest Greenland, scientists joined a traditional hunt to document narwhal sightings and behavior, showing how hard these whales are to spot.
