Tracing ocean chemistry in the field

The Reading Rainbow guy in Star Trek Next Generation was born blind, but able to see through his VISOR and, later on, via prosthetic ocular implants. By analogy, field geochemists now have new vision. Although, the device is not installed in a visor or as a prosthetic ocular implant, the new generation of energy-dispersive X-Ray … Read More

Laser based carbon spectroscopy

As a student in isotope geochemistry, the first words you will hear is “mass spectrometry”. Perhaps one day in the future, the first words will be “cavity-ring down spectrometry”. In a study led by David Balslev-Clausen, we measured carbon isotope compositions in rocks to compare the performance of conventional mass spectrometry and the brand new … Read More
