Chemistry From Another World Found in The Famous Hillsborough Meteorite - ScienceAlert

He was looking for microscopic shells in a Sarasota County quarry. What he found sat in a drawer for years before anyone understood where it came from. In the summer of 2006, Mike Meyer was doing the kind of work that never makes the news. An undergraduate at the University of South Florida, he had joined a fieldwork project in a quarry in Sarasota County, on Florida’s Gulf Coast, led by Roger Portell of the Florida Museum of Natural History. The students were collecting fossil clams, and Meyer’s job was to sieve the sediment packed inside them.

The spacecraft delivered materials and equipment for new research studies to the station.

Mud from a fjord shows an Atlantic air pattern brought wetter, colder spells to southern Greenland, a clue to how its ice may fare. Greenland’s ice is shrinking as the planet warms. But in the island’s southwest, rainfall and snowfall have been influenced by the same North Atlantic air-pressure pattern for at least 5,000 years. When that pattern tipped one way, the region turned wetter and colder. The record comes from mud on the floor of a Greenland fjord, and it suggests snowfall, not only temperature, shaped how the area’s ice grew and shrank. It doesn’t yet show how glaciers there will respond to the warming ahead. Johan Faust, a researcher at MARUM, the Center for Marine Environmental Sciences at the University of Bremen in Germany, led the work with colleagues in Germany, Norway, Denmark and Canada. A seesaw in the airThe pattern is called the North Atlantic Oscillation. It’s the difference in air pressure between a low that sits near Iceland and a high near the Azores, and it’s strongest in winter. When that difference is large, the pattern is in its positive phase. Northwestern Europe and southwestern Greenland both get more rain and snow.
