For applications ranging from the long term assessment of the variability of the living resources of the sea, to the navy strategic blue-green laser project, a need has for instrumentation to measure the optical properties of seawater which is easily deployed from a variety of platforms and can be… More

This work will examine the feasibility of commercially producing a second generation fluorometer that will significantly enhance the research and sampling capabilities of marine and freshwater biologists and fisheries scientists who routinely monitor the crop size, taxonomic composition, and… More

The field of marine photochemistry is a special focus area for onr, and the leading researchers in this field have voiced a strong need for instrumentation to measure the attenuation of ultraviolet light in the ocean. biospherical instruments is the leading developer of new types of optical… More

The proposal presents a design for a visibility monitoring instrument for use underwater at low light levels. the instrument will use solid state photodetectors, and will provide a dynamic range of 10 to the 5th power to 10 to the - 6th power foot-candles in conjunction with a 10 cm. path… More

This proposal addresses the need for cost effective surface validation instrumentation for future ocean color sensors, both the pending seawifs satellite, and the planned high resolution scanning sensors such as modis and hiris. the significant innovation proposed couples optical fibers with high… More

Since the discovery of the "ozone hole" the monitoring of long term trends and geographical variability of uv irradiance and how it impacts our environment has become increasingly important. there is an immediate need to deploy networks of suitable instrumentation yet there appears to be no… More

Radiometers are a crucial element in NASA's studies of Planet Earth. This proposal addresses the basic need for a miniature spectrometer, flexibly configurable and optimized for above and in-water optical property measurements. The innovation we are proposing develops a 1 cm diameter photodetector… More
