Elemental Traces in the Atlantic: The art of clean sampling

Follow my blog at EARTH online, "Elemental Traces in the Atlantic," over the next couple of months, where I’ll be writing from the ship and detailing the scientific journey. And stay tuned early next year, when EARTH and I will bring you a wrap-up of the cruise. Read the original story here.

Think of the cleanest, most meticulous person you know and multiply that attention to detail by about an order of magnitude. That’s what it takes to be considered trace-metal “clean.”

Elemental Traces in the Atlantic: The final chapter

Jeremy Jacquot's blog for EARTH, "Elemental Traces in the Atlantic," detailed the scientific journey of the first U.S. GEOTRACES expedition. Read his other blogs here and here, and the original story on GEOTRACES as it appeared in EARTH here. Stay tuned for a wrap-up of the cruise in EARTH early next year.

Blogging on EARTH: EGU: Geologists help law enforcement

EARTH’s Carolyn Gramling is in Vienna, Austria, at the European Geophysical Union meeting this week. One session in particular caught her attention this week — how geoscientists are creating new maps and tracking mechanisms to help law enforcement officials. For more from the meeting, see her first and second dispatches.

Cold case files: Forging forensic isoscapes

In November 2006, someone left a badly beaten man at a hospital in Gwent, South Wales. The victim was severely injured and died shortly thereafter without revealing his identity. All the Gwent police knew about the John Doe was that he was Asian, or of Asian descent, and possibly Vietnamese. There was no record of him entering the country. His fingerprints provided no further information on his identity. The trail went cold.

Cruising the Atlantic to trace elemental movements

When it comes to the science of climate change, one of the least understood issues is the oceans’ future in a changing global environment. Measurements over the past two decades show that the oceans’ surface waters have been warming since the 1950s, and that large influxes of carbon dioxide have already made the oceans more acidic.
