The Boston College Marine Biogeochemistry Laboratory is a 593-square foot analytical chemistry laboratory space renovated in 2020. Our research group uses this space to prepare equipment and sampling supplies prior to conducting fieldwork, and to analyze samples collected in the field. The lab is adjacent to a shared meeting and office space with work stations for members of the lab group conducting computational data analysis, with a window that provides visual continuity into the analytical chemistry laboratory. The lab includes a fume hood, two sinks (one of which is ADA-compliant), benchtop space that includes an adjustable-height section to accommodate wheelchair users, and a 400-L sensor test tank with temperature control and plumbing to bubble the test tank with up to three gasses regulated by mass flow controllers.
