In 2025, Sequoia was awarded a NASA SBIR Phase II grant to continue the development of a submersible hyperspectral transmissometer (Hyper-c) in support of ocean color and biogeochemistry research. The 2-year project continues and expands upon our Phase I work effort, with the goal of developing the Hyper-c into a commercial product by 2027/2028.
