Researchers Model Differences in East Coast Sea Level Rise

For years, scientists have been warning of a so-called “hot spot” of accelerated sea-level rise along the northeastern U.S. coast. But accurately modeling this acceleration as well as variations in sea-level rise from one region to another has proven challenging. Now new research offers the first comprehensive model for understanding differences in sea level rise along North America’s East Coast.

In Greenland, Exactly Where Meltwater Enters the Ocean Matters

In southern Greenland in summer, rivers have been streaming off the ice sheet, pouring cold fresh water into the fjords. A new study tracks where that meltwater goes—with surprising results.

End of the Line – Good Byes to a Great Field Season in Peru

After more than six weeks trawling the Peruvian Andes in search of palaeoclimate clues, our field team is visiting the last site, a potential calibration sites near Coropuna. The objective of that ongoing work is to refine the cosmogenic surface-exposure method for the tropics, thereby improving the precision of new and existing datasets.

On the Subject of Dust

Our field team has set camp at 5045 m on the dusty slopes of Ampato, an extinct, ice-clad volcano in the Western Cordillera. This is the very mountain from which Juanita, the famous Incan ‘ice maiden’, was plucked back in 1995. The tents are clustered in the lee of a large glacial erratic and, now the clouds have cleared, the view is second to none, taking in the dry plains far below and myriad volcanic peaks in every direction.

Going West

After a busy few weeks in the Cordillera Carabaya, our field team has said goodbye to the snowy, tempestuous climate of the eastern Andes and is moving west to the desert of Arequipa. Here the mountains are massive, isolated volcanoes, many of which exceed 6000 m in elevation. In fact, Coropuna is the third highest mountain in Peru and certainly the most sprawling.

Mad Dogs and Englishmen

Our field team has acquired a dog, ¨”Mooch”. Walking back to camp yesterday, amid driving snow and fully laden with rock samples, there he was exploring what passes for our kitchen. Unlike most Andean dogs – ferocious beasts trained to keep geologists from harassing the livestock – this one is a cheerful soul, happy to hang around and be fed whatever is going, and always up for affection.

Ancient mud from the high Andes

Thanks in large part to Matt, an undergraduate from Pacific Lutheran University in Washington, our field team now has more than sixty samples for surface-exposure dating. This is no easy feat, for collecting these samples requires a great deal of hammering on granite boulders with nothing more than a hammer and chisel. There are other ways of doing it, such as using small explosive charges, rock saws, or splitting wedges, but we find that good old-fashioned hammering is by far the safest way.

A typical day in the high Andes

Each morning starts the same in the Andes: the frost is heavy on the insides of our tents and falls with the slightest movement, while the realization that it´s going to be a freezing exit from the sleeping bag is tempered by gratitude that the thirteen hour night is over. Yes, sunrise in the Andes is a momentous occasion each day, one that feels a million miles away from home.
