Tracking trace elements and isotopes in the oceans

A report from the GEOTRACES cruise across the Atlantic

For decades, scientists have been trying to piece together the enormously complicated puzzle that is the ocean. They have collected many different kinds of information, from trace elements like iron to tritium isotopes, from many different parts of the ocean. Bringing together these disparate pieces to form a more complete picture is crucial to understanding how human activities, the marine food web, the global carbon cycle and the circulation of seawater are all interconnected.

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.

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.”
