Marking the 100th anniversary of AGU and Eos, this collection celebrates a century of achievements in the Earth and space sciences and looks forward to the next 100 years of scientific discovery and transformation.
Seismometers near Iceland’s Bárðarbunga volcanic system pinpointed thousands of earthquakes in 2014–2015, revealing where molten rock was moving underground before any eruptions occurred.Read More »Hydrology, Cryosphere & Earth Surface
Scientists were studying ecohydrology for decades before it became an official ‘ology’. Find out how this field has evolved over the past century.Read More »Hydrology, Cryosphere & Earth Surface
A map of the world’s free-flowing rivers shows a shrinking number can still meander as they please. New plans for hydropower will further constrain flow.Read More »Hydrology, Cryosphere & Earth Surface
The underside of the world’s largest ice shelf is melting—by meters per year in some places—because of the seasonal inflow of water heated by the Sun, observations of the White Continent reveal. Read More »Ocean Sciences
Ocean samples collected from around the world produced a twelvefold increase in the number of marine viruses known. A portion of the Arctic Ocean has “surprisingly high diversity.”Read More »Planetary Sciences
Samples returned from the surface of an asteroid show that these small bodies may have more water than previously thought and could have delivered that water to Earth.Read More »
Asymmetrical changes in ocean circulation and the marine carbon cycle could account for different degrees of ocean acidification between the Pacific and Atlantic.Read More »Geology & Geophysics
Scientists get one step closer to being able to predict jerks—notoriously capricious changes to Earth’s geomagnetic field detectable by satellites.Read More »
