In November 1923, newspapers such as The New York Times reported on a desert whose name was unfamiliar to most Westerners: the Gobi. The Central Asiatic Expeditions of the American Museum of Natural History (AMNH), led by Roy Chapman Andrews, had returned with tons of fossils and what the press hailed as the first dinosaur eggs ever discovered, preserved in the sandstone of the Flaming Cliffs. The museum took them for the eggs of Protoceratops. Some papers gave their age as ten million years, about seven times too young. The eggs were shipped to New York, where they caused a sensation. The nests had remained intact for seventy million years. Next to them lay the skeleton of a small, toothless, beaked dinosaur, with its skull just four inches (about 10 cm) above the eggs. Henry Fairfield Osborn named Oviraptor, the 'egg-seizer', combining the Latin 'ovum' (egg) with 'raptor' (robber, plunderer). The species name, philoceratops, "lover of ceratopsians," completed the verdict: that beak seemed made for cracking the eggs of Protoceratops. Osborn later recognised that this might mislead us as to its feeding habits. He was right. In 1993, a team from the AMNH and the Mongolian Academy of Sciences found an embryo inside an egg of the same type, showing that these eggs were oviraptorid, not Protoceratops (Norell et al., 1994). In the following years, oviraptorids such as Citipati were found fossilized sitting on their nests with their arms spread over the clutch (Norell et al., 1995; Clark et al., 1999). The supposed thief had been a devoted parent, and one of the researchers, James Clark, even titled a 1995 article "An egg thief exonerated."

AGU is thrilled to be back in San Francisco and bring you some exciting and informative science policy programming at this year's annual meeting. Whether you're new to science policy or are looking to start a policy career, we have a session for you. This year, all our core programming will take place in AGU Central's theater space, located in the exhibit hall. Sessions will be 45 minutes...

John Hillier (Interim Division President): I have a very mixed research background. I started off in marine geophysics and then I moved to glacial geomorphology. At the end of that I worked for an insurance company as a catastrophe modeller, and then returned to the academic space looking at multi-hazard risk. I've been working with the insurance companies, to look at when risks co-occur, identify the natural hazards and their impact on regulations. So I've chased my research all the way from science to communication.

How do geodesists measure gravity? And what does it reveal about our planet? Gravitation is one of the most familiar forces in everyday life, yet almost no one can explain how geodesists use it to monitor a changing Earth. A new short film from IAG's Global Geodetic Observing System (GGOS), "Gravity - The Invisible Force Shaping Our Earth" sets out to change that translating decades of geodetic gravity research into eight minutes that anyone can follow.

As exploration challenges become increasingly complex, two complementary workflows have emerged as the foundation of effective petroleum systems studies: bottom-up basin modelling and top-down fluid systems analysis. The traditional bottom-up approach reconstructs the geological evolution of a sedimentary basin through time. The principal strength of bottom-up modelling lies in its ability to quantify geological processes...

If you want to run a hydrological model  anywhere, the first question is which meteorological forcing to use. For the Po basin, or anywhere in northern Italy,  there are today at least a dozen gridded products, regional and European, built from different meteorological networks, with different methods and for different purposes. I reviewed them from one point of view: that of a hydrologist who needs daily forcing to close water budgets with a distributed model. The full review, with tables, station counts and references, is in my blog: Daily forcings datasets: rainfall and temperature in the Po River District. Here, I provide a summary.

Like many of you, I have dedicated myself to AGU because I want to ask a bigger question than, "How do we protect what we have?" I believe we should be asking, "If we were building the scientific enterprise today, what would we create?" The scientific community is in the midst of severe challenges. We can react to each of them, or we can seize the opportunity in front of us--to reenvision the...

Small glaciers are often written off: too small to matter, and soon gone anyway. Yet recent disasters in the Alps show that they can still pose a threat. And some are doing something rather unexpected: while the climate warms, the ice inside them has turned cold. We drilled into six small Swiss glaciers to find out why, and why it matters.
