Scientists locate whistling space electrons’ origins

Blog— Scientists have long known that solar-energized particles trapped around the planet are sometimes scattered into Earth’s upper atmosphere where they can contribute to beautiful auroral displays. Yet for decades, no one has known exactly what is responsible for hurling these energetic electrons.... more

How Earth’s Orbit Affected Ice Sheets Millions of Years Ago

Emily Underwood, Freelance Writer

A new study of the late Pliocene era could help scientists predict future sea level rise.  When Earth’s atmosphere warms, the vast sheets of ice over Antarctica and Greenland melt. This melting, in addition to the thermal expansion of water, leads to rising sea levels. Although it’s clear that seas.... more

New Antarctic heat map reveals sub-ice hotspots

Blog— An international team of scientists, led by British Antarctic Survey (BAS), has produced a new map showing how much heat from the Earth’s interior is reaching the base of the Antarctic Ice Sheet. The map is part of a new paper accepted for publication in Geophysical Research Letters, a journal.... more

Groundwater recharge in the American west under climate change

Blog— Groundwater recharge in the Western U.S. will change as the climate warms–the dry southern regions will have less and the northern regions will have more, according to new research. “Our study asked what will be the effect of climate change on groundwater recharge in the Western U.S. in the near.... more

How Quickly Is Mercury’s Surface Evolving?

From Eos.org: Research Spotlights— New measurements of impact craters on Mercury’s smooth plains suggest the topography of the solar system’s innermost planet is changing at twice the rate of landforms on the Moon.  For the last several billion years, collisions with meteoroids, asteroids, and comets.... more

Scientists may have solved mystery of rapidly rising Indian Ocean sea level

Blog— Sea levels around the world have risen by 1.7 millimeters (0.07 inches) on average each year since 1880, but in recent years, scientists have observed a rapid increase in sea level in the north Indian Ocean. Tide gauge records and other datasets reveal the pace of sea level rise in the north Indian.... more

More Greenland glaciers threatened by climate change than previously thought

Press Release—  New maps of Greenland’s coastal seafloor and bedrock beneath its massive ice sheet show that two to four times as many coastal glaciers are at risk of accelerated melting due to climate change as previously thought. In a new study, researchers at the University of California at Irvine.... more

Triggers for the spring phytoplankton bloom

Editor’s Highlight—   Within ocean sciences, there is currently considerable interest in mesoscale eddies and their impacts on biology. This paper makes a contribution to this scientific field by examining how mesoscale eddies affect the timing of the spring bloom of phytoplankton in the Japan Sea..... more

New Insight into Ionospheric Feedback Instability

Gang Lu, Editor, Geophysical Research Letters

Editor’s Highlight— A new modeling effort could change our understanding of auroral arc formation. The ionospheric feedback instability describes the fast, spontaneous break-up of large-scale field-aligned currents flowing through a low-conductivity ionosphere. Since the seminal paper by Atkinson in.... more

Early Results: Juno at Jupiter 

Early results from Juno's mission at Jupiter including approach to Jupiter and the first perijove pass (PJ1). Juno's scientific objectives include the study of Jupiter's interior, atmosphere and polar magnetosphere with the goal of understanding Jupiter's origin, formation and evolution. This collection of papers provides early results from Juno's measurements of the gravity and magnetic fields, deep atmospheric microwave sounding, infrared, visible and ultraviolet images/spectra and an array of fields and particles instruments as well as context for the early results with respect to current theory and models of Jupiter's formation and evolution. Topics include both Juno - Jupiter related theoretical models and data analysis as well as collaborative observations made from Earth based assets.
