Versatile platform for measuring optical properties in a variety of aquatic environments.

The Free-Falling Optical Profiler, or Profiler II, measures the color of the ocean and how it varies spectrally throughout the euphotic zone. The Profiler II is used by the US, Canada, UK, France, Italy, Australia, Brazil, China, Taiwan, Korea, Japan, India, Germany and Israel to provide calibration and validation data for ocean color satellites. The Profiler II is also the workhorse sensor suite for the global optical oceanography community who investigate basic fundamental biological and physical processes that involve light in the ocean.

The Free-Falling Optical Profiler offers researchers the unique opportunity to use this system as a free fall profiling device or in conjunction with a detachable float for near-surface measurements (HyperTSRB). The Profiler II is designed to interchange Sea-Bird Scientific’s hyperspectral or multispectral optical sensors making this system the most versatile platform for measuring the apparent optical properties of the ocean.

The Profiler II system comes complete with a molded flotation collar that is easily mounted to the profiling frame for real time, near-surface measurements. Upwelling radiance and irradiance measurements can be collected as close as 5 cm from the sea surface.

The optional integration of Sea-Bird Scientific ECO series sensors offers a new combination for concurrent determination of chlorophyll fluorescence and optical backscattering in either profiling or surface mode.
