            "description": "Using observations from NASA’s ICON mission, scientists presented the first direct measurements of Earth’s long-theorized dynamo on the edge of space: a wind-driven electrical generator that spans the globe 60-plus miles above our heads. The dynamo churns in the ionosphere, the electrically charged boundary between Earth and space. It’s powered by tidal winds in the upper atmosphere that are faster than most hurricanes and rise from the lower atmosphere, creating an electrical environment that can affect satellites and technology on Earth. The new work, published today in Nature Geoscience, improves our understanding of the ionosphere, which helps scientists better predict space weather and protect our technology from its effects.More information: https://www.nasa.gov/feature/goddard/2021/strong-winds-power-electric-fields-in-upper-atmosphere-icon/ || ",

Relatively understudied, Nansen’s manageable size lends itself to becoming a proxy for predicting how larger ice shelves will contribute to sea level rise in the decades and centuries to come. By studying the impact of tides, Walker and Dow are able to determine how the rise and fall of floating ice sheets may impact the likelihood of an eventual ice shelf collapse.Complete transcript available.Music: Tiptoe Marimba by Brightside Studio || LARGE_MP4-Nansen_0711217_FINAL_V3_large.00001_print.jpg (1024x576) [78.0 KB] || LARGE_MP4-Nansen_0711217_FINAL_V3_large.00001_searchweb.png (320x180) [57.6 KB] || LARGE_MP4-Nansen_0711217_FINAL_V3_large.00001_thm.png (80x40) [4.4 KB] || LARGE_MP4-Nansen_0711217_FINAL_V3_large.00001_web.png (320x180) [57.6 KB] || APPLE_TV-Nansen_0711217_FINAL_V3_appletv.m4v (1280x720) [129.6 MB] || FACEBOOK_720-Nansen_0711217_FINAL_V3_facebook_720.mp4 (1280x720) [302.8 MB] || LARGE_MP4-Nansen_0711217_FINAL_V3_large.mp4 (1280x720) [244.4 MB] || Nansen_0711217_FINAL_V3.mov (1280x720) [2.6 GB] || TWITTER_720-Nansen_0711217_FINAL_V3_twitter_720.mp4 (1280x720) [53.9 MB] || WEBM-Nansen_0711217_FINAL_V3.webm (960x540) [97.5 MB] || YOUTUBE_1080-Nansen_0711217_FINAL_V3_youtube_1080.mp4 (1920x1080) [403.4 MB] || YOUTUBE_720-Nansen_0711217_FINAL_V3_youtube_720.mp4 (1280x720) [404.4 MB] || APPLE_TV-Nansen_0711217_FINAL_V3_appletv_subtitles.m4v (1280x720) [129.7 MB] || 12666_Nansen_080717.en_US.srt [4.4 KB] || 12666_Nansen_080717.en_US.vtt [4.4 KB] || Nansen_0711217_FINAL_V3_lowres.mp4 (480x272) [32.5 MB] || ",

            "description": "Earth’s magnetic field is built up from many contributing sources ranging from the planet’s core to the magnetosphere in space. Untangling and identifying the different sources allows geomagnetic scientists to gather information about the individual processes that combine to create the full field.One contributor is the ocean. But how do the tides affect Earth’s magnetic field? Seawater is an electrical conductor, and therefore interacts with the magnetic field. As the tides cycle around the ocean basins, the ocean water essentially tries to pull the geomagnetic field lines along. Because the salty water is a good, but not great, conductor, the interaction is relatively weak. The strongest component is from the regular lunar tide that happens about twice per day (actually 12.42 hours). Other contributions come from ocean swell, eddies, and even tsunamis.The strength of the interaction also depends on the temperature of the ocean water. Scientists are now able to determine how much heat is being stored in the entire ocean, from wave top to sea floor by observations of the Earth's magnetic field. || ",
