A comprehensive collection of variation in Earth's gravity could aid studies of the Antarctic geoid and of Antarctica's geology and ice sheet dynamics.
Spectral data from NASA's MESSENGER spacecraft indicate that the properties of the depressions on Mercury's surface can vary within a single crater and that these differences may correlate to age.
Scientists use very low and low-frequency radio signals to detect short gamma ray bursts and their impact on the low ionosphere.
A computer simulation shows a net increase in primary production by phytoplankton if climate change were mitigated by 2200 but also indicates big changes in the makeup of those species.
A new model shows that a spiral wave may explain why many phenomena in the gas giant's magnetosphere undergo periodic cycles.
In the 2000s, the North Atlantic stopped absorbing as much atmospheric warmth. However, the ocean lost only a little heat—the rest was held deeper below the surface by altered circulation patterns.
A seismically quiet part of the Aleutian Subduction Zone may have caused tsunamis in the past—and may cause future tsunamis that could travel across the Pacific Ocean.
Scientists use seismic stations to study ice shelf vibrations generated by ocean waves to better understand their impact on the integrity of the Ross Ice Shelf.
Volcanic eruptions aren't all bad—in some cases, they can lower the frequency of tropical cyclones in the North Atlantic by emitting sulfate aerosols.
Modeling experiments demonstrate that strong El Niños greatly increase odds for wet winters over California's principal watersheds compared to impacts of weak and moderate El Niños.
