In 1923 the Flaming Cliffs of the Gobi Desert yielded one of the most-celebrated finds of paleontology. Entombed in sun-baked sandstone was a collection of oval-shaped oddities: the first dinosaur eggs known to science. This 75-million-year-old find would be followed by others, providing a glimpse into the lives of these ancient creatures that no skeleton could.

Since that discovery, fossilized dinosaur eggs and nests have been recovered from sites around the world, as have the bones of tiny hatchlings and even tinier embryos. These discoveries are allowing scientists to unlock the mysteries of dinosaur reproductive and social behavior, such as: Were dinosaurs social animals? Did they care for their young? What was life like for baby dinosaurs? (more…)

Study of Patagonian Glacier’s Rise and Fall Adds to Understanding of Global Climate Change

Glaciers play a vital role in Earth’s climate system, and it’s critical to understand what contributes to their fluctuation.

Increased global temperatures are frequently viewed as the cause of glacial melt, but a new study of Patagonia’s Gualas Glacier highlights the role of precipitation in the glacier’s fluctuation. The study, conducted by Sébastien Bertrand of the Woods Hole Oceanographic Institution (WHOI) and his colleagues, reconstructs a 5,400 year-record of the region’s glacial environment and climate, comparing past temperature and rainfall data with sediment records of glacier fluctuations and the historical observations of early Spanish explorers.

*History of influence of industrial revolution hidden in glacial ice*

New clues about how Earth’s remote ecosystems have been influenced by the industrial revolution have been uncovered. Until now they were locked away, frozen in the ice of glaciers.

So say scientist Aron Stubbins of the Skidaway Institute of Oceanography and colleagues. (more…)

Melting Ice on Arctic Islands a Major Player in Sea Level Rise

ANN ARBOR, Mich.— Melting glaciers and ice caps on Canadian Arctic islands play a much greater role in sea level rise than scientists previously thought, according to a new study led by a University of Michigan researcher.

The 550,000-square-mile Canadian Arctic Archipelago contains some 30,000 islands. Between 2004 and 2009, the region lost the equivalent of three-quarters of the water in Lake Erie, the study found. Warmer-than-usual temperatures in those years caused a rapid increase in the melting of glacier ice and snow, said Alex Gardner, a research fellow in the Department of Atmospheric, Oceanic and Space Sciences who led the project. The study is published online in Nature on April 20. (more…)
