Using mass spectrometers can be a rite of passage, says MIT-WHOI graduate student Sarah Rosengard. The samples analyzed by mass specs also undergo a rite of passage, undergoing brief but transformative journeys inside.
Image Of the Day caption:
MIT-WHOI Joint Program student Sarah Rosengard converts organic carbon to carbon dioxide by slowly increasing its temperature from room temperature to 800?C (1,470?F) at WHOI's National Ocean Sciences Accelerator Mass Spectrometry (NOSAMS) Facility. The "mass spec" is used by scientists around the world to analyze the origin of carbon in the marine ecosystem, study ocean circulation in the distant past, and understand the cycling of carbon in the modern ocean. Such work is particularly essential to monitor changes in the global carbon cycle, as rising CO2 levels cause changes in the world climate.
