Woods Hole Oceanographic Institution

Woods Hole Oceanographic Institution (WHOI) is developing a system-on-a-chip for ocean carbon flux monitoring that would integrate the capabilities of several existing commercial sensors into a single miniature sensor chip, lightening the power requirements on ocean gliders and floats and reducing costs by an order of magnitude. The proposed system-on-a-chip would measure pH, oxygen, particulate organic carbon, and other variables. Unlike state-of-the-art sensors that are built in small batches by hand, WHOI’s system-on-a-chip would fabricate and calibrate at scale using semiconductor manufacturing techniques while still meeting or exceeding current accuracy and precision standards.
