NOSAMS leading ¹⁴C-DIC interlaboratory comparison

Internationally recognized standard material does not exist for the ¹⁴C analysis of dissolved inorganic carbon (DIC), creating challenges for laboratories seeking to carry out this analysis. NOSAMS is leading an effort to carry out the first ¹⁴C-DIC interlaboratory comparison. The exercise will include surface and deep (2200 m) seawater collected from Station ALOHA located in the North Pacific subtropical gyre. Depending on availability, we will also distribute radiocarbon depleted groundwater.

If you would like to participate in the intercomparison please let us know here.

Call for Applications: NOSAMS Postdoctoral Scholar

We invite applications from innovative and driven researchers to carry out radiocarbon research at the NOSAMS facility. We seek an outstanding individual to pursue work in one or both of the following areas: (i) radiocarbon in oceanic systems (ii) advances in accelerator mass spectrometry and related techniques. Applicants can carry out research with any WHOI scientific staff member on their research interests. Applications are due December 1, 2025. More information can be found here.
