The proposed sensor addresses several NASA interests under the S1.09 "Surface & Sub-surface Measurement Systems" subtopic, including particle characterization, water quality, IOP measurements for calibration and validation of ocean color data, proxies for biogeochemical particle composition, and properties of aquatic environments such as detection of phytoplankton and their functional groups. All aspects of optical oceanography research, including biology, particle analysis, and ocean color remote sensing rely on measurements of these key IOPs. Researchers using autonomous platforms are a key market since absorption is not currently measured on these platforms due to limitations of current absorption sensors (e.g., flow-through design, size, power demand, fouling). The flat-faced design also allows for easy incorporation of shutters or wipers to prevent fouling for moored and other long term deployments such as in ocean observatories. The simple and compact design is highly desired for incorporation into existing profiling CTD rosettes used routinely in oceanography. The proposed sensor measuring absorption and backscattering across a wide range of platforms and scales has wide applicability in the field of ocean optics and ocean biology and biogeochemistry. NASA scientists and NASA-funded researchers in these fields routinely measure in-water IOPs and the target market for this sensor is extremely broad.
Similar to the NASA Applications, the target market for the proposed sensor is extremely broad. Government scientists and agency-funded researchers (many federal agencies including NSF, NRL, ONR, NOAA, as well as state environmental agencies) in ocean science and coastal monitoring routinely measure IOPs, and the ability to incorporate a wider range of measurements (especially including absorption) on a wide range of platforms covering a wide range of scales is a critical need.
