Study challenges role of Antarctic meltwater in sequestration (10 sources) This story has been covered by multiple news sources, providing comprehensive coverage from different perspectives. **oceanographicmagazine.com** reports: Study challenges role of Antarctic meltwater in sequestration Study challenges role of Antarctic meltwater in sequestration Study challenges role of Antarctic meltwater in sequestration **www.euronews.com** reports: Could glacier melt slow climate change? Scientists thought so – until now | Euronews The Amundsen Sea accounts for most ... by Antarctic melting. Here, glacial meltwater comes from beneath floating ice shelves, primarily driven by warm water flowing from the deep ocean into the cavities under the ice. ... Iceland saw record temperatures last year. So why are scientists predicting a ‘deep freeze’? ‘Doomsday Glacier’ is melting faster than we thought. Can a 150-metre wall stop it flooding Earth? To measure how much iron this meltwater ... **www.sciencedaily.com** reports: A major climate hope in Antarctica just melted away | ScienceDaily Sign up for our free email newsletter. ... A popular climate theory suggested that melting Antarctic glaciers would release iron into the ocean, sparking algae blooms that pull carbon dioxide from the air. New field data from West Antarctica reveal that meltwater provides far less iron than ... **www.earth.com** reports: Antarctica’s melting ice won’t help fight climate change after all - Earth.com To test this idea, scientists from ... in West Antarctica in 2022. They used a research ship called the Nathaniel B. Palmer. Warm deep ocean water flows under the floating ice shelf and melts it from below. This process creates a circulation system known as the meltwater pump. The system mixes meltwater with deep ocean water and pushes it upward toward the surface. The researchers wanted to measure exactly how much iron entered and ... **www.theweather.net** reports: Antarctic meltwater has delivered far less iron than climate models assumed New Antarctic field data have shown meltwater has delivered far less iron than expected, challenging a key idea about natural CO₂ drawdown. **www.nature.com** reports: Iron supply to the Amundsen Sea, Antarctica is dominated by circumpolar deepwater and continental subglacial sources | Communications Earth & Environment Glacial melting in West Antarctica has intensified with the increased intrusion of warm ocean water beneath ice shelves, but the processes controlling the export of meltwater-associated micronutrient iron (Fe) to Southern Ocean surface waters remain unclear. **en.clickpetroleoegas.com.br** reports: Antarctic glaciers are melting at an accelerated rate, but can they help reduce carbon dioxide? Research conducted by Rutgers University at Thwaites Glacier shows how iron fertilization works in practice and what the true role of melting ice is in sea level rise - CPG Click Oil and Gas Furthermore, the researchers identified ... surface meltwater. Sherrell explained that most of the iron results from the crushing and dissolution of the bedrock beneath the ice. Therefore, the data indicate that thawing, by itself, does not act as a significant carbon capture mechanism. Now, scientists are advocating for new investigations to understand the sources of iron in Antarctica in a warming ... **earth.com** reports: Antarctica’s melting ice won’t help fight climate change after all - Earth.com Some climate models even included this idea when predicting future climate change. To test this idea, scientists from Rutgers University New Brunswick and other institutions traveled to the Dotson Ice Shelf in West Antarctica in 2022. They used a research ship called the Nathaniel B. **theweather.net** reports: Antarctic meltwater has delivered far less iron than climate models assumed But fresh field measurements from West Antarctica have put a big question mark on that. Researchers from Rutgers University-New Brunswick say meltwater from an ice shelf has supplied far less iron than many studies had assumed - and most of the iron in the area appears to be coming from elsewhere. **www.sciencedaily.com** reports: Top Science News -- ScienceDaily Top science stories featured on ScienceDaily's home page.
