New data potentially confirms presence of intact lava tubes on the Moon

Editor’s Highlight—   Speculation about the presence of lava tube caves on the Moon has been around since the Apollo era. However, it wasn't until the discovery of several lunar pits/voids in mare units that there were locations to focus studies with geophysical instruments. This paper potentially confirms.... more

Improving the representation of the global ocean heat content

Editor’s Highlight—   This manuscript utilizes top-of-atmosphere radiation measurements to better constrain ocean reanalysis, providing a means of predicting where heat is taken up and stored within the oceans. The technique seems obvious in hindsight, but to my knowledge this hasn't been tried before..... more

Exploring the mismatch between modeled and observed Antarctic sea ice area

Editor’s Highlight—   This paper helps to show that ice shelf melting is important in the ability of climate models to simulate the positive Antarctic sea ice trends. The authors perform a series of modeling experiments to simulate the effect of freshwater input from Antarctic ice shelves on the modeled.... more

Secrets of hidden ice canyons revealed

Blog— We are all aware that Antarctica’s ice shelves are thinning, but new research shows they may be even more fragile than previously thought. In a new study published in Geophysical Research Letters, a journal of the American Geophysical Union, scientists have discovered huge canyons cutting through.... more

Variations in salt transport by the Florida Current

Editor’s Highlight—   In order to understand variability in freshwater and Atlantic meridional overturning circulation (AMOC), it is necessary to understand the sources of variability in salt transport by the underlying Florida Current. This paper presents an analysis of observations of the Florida.... more

New study explains how continents leave their roots behind

Blog— In some areas of the seafloor, a tectonic mystery lies buried deep underground. The ocean floor contains some of the newest rock on Earth, but underneath these young oceanic plates are large swatches of much older continents that have been dislocated from their continental plates and overtaken.... more

Imaging the Underlying Mechanics of New Zealand Earthquakes

Sarah Witman, Freelance Writer

From Research Spotlights— Researchers create a first-of-its-kind image to map electrical properties of rocks and minerals throughout the Hikurangi subduction zone.  New Zealand’s North and South Islands are well known for providing picturesque scenery. Beneath its bucolic veneer, however,.... more

Ocean Dynamics May Drive North Atlantic Temperature Anomalies

From Research Spotlights— A new analysis of sea surface temperature and salinity over several decades seeks to settle the debate on which of two mechanisms underlies the Atlantic Multidecadal Oscillation.  For at least the past 1,000 years, the surface waters of the North Atlantic Ocean have.... more

Old Faithful’s geological heart revealed

Blog— Old Faithful is Yellowstone National Park’s most famous landmark. Millions of visitors come to the park every year to see the geyser erupt every 44-125 minutes. But despite Old Faithful’s fame, relatively little was known about the geologic anatomy of the structure and the fluid pathways that.... 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.
