South Africa-Bound with Sand from Coney Island
I’m flying to Johannesburg on Friday in what will be my third expedition to South Africa. In the past I’ve traveled here to study the Bushveld Complex, a huge lava formation that provides over 70 percent of the world’s platinum as well as other valuable ores, such as vanadium and chromium, both used to make…

Beyond Carbon: How Fixing the Ozone Layer Contributes to Climate Change
The greenhouse effect is not all about carbon dioxide. Several other substances, such as water vapor and methane, also play a key part in trapping radiation. Recently, a family of relatively obscure chemicals called hydrofluorocarbons, or HFCs, has entered the spotlight due to its role in global warming. HFCs are highly potent greenhouse warmers –…

Ice on Ice
I have reached Jakarta, and so have the ice cores, which are being kept frozen while awaiting air shipment to the United States. The rest of the team has already returned to their homes. Next for me: back to sea level, on two research cruises that will add oceanographic information to the data we gathered on Puncak Jaya.…

Connecting Young and Old
Nano and I took the train to Rome to meet a colleague for lunch, and after we explored the old city. I have been through Rome a number of times, making my way to and from Calabria, but this was my first time really seeing the city. Nano was a fantastic tour guide. He was…

Hiking Monte Pollino
I grew up in a family that drove on vacations, be it six hours to the beach, eight hours to see relatives, or three days to Idaho. So the seven hour drive from Calabria to Rome is no big deal, although the lack of air conditioning does make it undesirable. When I tell my friends…

Finished, as the Glaciers Fall Apart
We have finished our mission at Puncak Jaya and removed the ice cores, along with all camps and people from the field. Currently, we are in the coastal city of Timika for a few days, drying out our field equipment and tents. These are the first glaciers we have ever drilled where it rains almost every day–and…

Fitting Calabria through a Rocky Doorway
One of the challenges of studying the Calabrian subduction zone is the enormous variation over relatively short distances. Etna is located just 120 kilometers from Stromboli, yet the volcanoes have completely different sources of magma. Fluvial conglomerates in the Crotone Basin have lots of chert, yet conglomerates of the same age just 15 kilometers to…
