A large plasma hole generated by the vertical launch of the Formosat-5 satellite created temporary navigating and positioning errors of up to 1 meter, according to a new study.
Research Spotlights
Research spotlights are plain-language summaries of recent articles published in AGU’s suite of 24 journals.
Harnessing Remote Infrasound to Study Volcanic Eruptions
Data from the 2015 eruption of Chile’s Calbuco volcano suggest the international network built to monitor nuclear explosions may also be used to detect and characterize volcanic activity.
How Space Storms Affect the Satellite Superhighway
A powerful numerical model reveals how space weather disturbs magnetic field at geosynchronous orbit.
A Complete Picture of Southern Ocean Surface Circulation
For the first time, researchers combine estimates of sea surface height and circulation patterns in both ice-covered and ice-free regions of the Southern Ocean.
Capturing Structural Changes of Solar Blasts en Route to Earth
Comparison of magnetic field structures for 20 coronal mass ejections at eruption versus Earth arrival highlights the importance of tracking structural evolution to refine space weather predictions.
How Fast Is the Nile Delta Sinking?
New study calculates the delta’s subsidence on the basis of satellite data.
Life in the Hyporheic Zone
Defining the chemical relationships between water, sediment, and organisms that thrive beneath riverbeds.
Fossilized Caribbean Corals Reveal Ancient Summer Rains
Isotope records and climate modeling suggest that the rainy Intertropical Convergence Zone expanded northward into the southern Caribbean during a warm interglacial period about 125,000 years ago.
Evidence of Extensive Ice Deposits Near Mercury’s South Pole
New radar observations and refined illumination maps reveal uneven water ice deposits twice the size of those found around the planet’s north pole, suggesting the source may be a recent comet impact.
Tailoring Aerosol Injections to Achieve Desired Climate Effects
Two-dimensional simulations of sulfate aerosol injections suggest that solar geoengineering projects can be customized to maximize solar reflection and help achieve potential climate objectives.
