Students in teaching labs, as well as those conducting independent research, have access to the department's wide range of sophisticated calibrating and measuring instruments, which enable graduate-level analysis of data.
Scanning Electron Microscope (SEM)
A scanning electron microscope, acquired in 2016 with a grant from the National Science Foundation, provides a powerful tool for students, faculty, and visiting researchers to study the structure and composition of rocks, minerals, shells, and corals.

Electron Backscatter Diffraction (EBSD)
The EBSD system, by HKL Technology Inc., is an instrument used for the observation and analysis of microstructures and for phase identification.

The Bowdoin Buoy
Made possible by a grant from the National Science Foundation and the result of a partnership among Bowdoin, Bigelow Laboratory, and St. Joseph's College, the scientific buoy near the Schiller Coastal Studies Center in Harpswell Sound was installed to study Harmful Algal Blooms (HABs).

Gaz analyzer

Trace Gas Analyzer LI-7810

High performance CO2, CH4, and N2O gas analyzers for the field and lab.


Gas Chromatograph

Varian 450 GC

The Gas Chromatograph allows us the measure the concentration of CO2, CH4, and N2O gas in air samples.

High-pressure Liquid Chromatography (HPLC)
