Past Brew highlights from the Cafe Thorium


Café Thorium is not really a cafe although we have been known to serve espresso & latte throughout the worlds major ocean basins. In fact, we are a serious scientific research team in the Department of Marine Chemistry and Geochemistry at the Woods Hole Oceanographic Institution. Thorium is just one of many radioactive elements we measure. We analyze samples for both natural and man made radionuclides.

» For a fun article about our work, check out this short piece on serving espresso and science on the high seas (PDF).

» Here’s a short course in how Thorium helps us learn about how the ocean works.

Services & Facilities
While our T-shirt sales have been temporarily halted, the Café Thorium does provide radioanalytical services for the detection of natural and man-made radionuclides in environmental samples. We also have an archive of large volume (50 liter) seawater samples from the 1950’s-1980 that can be available for the right scientific project.
