Underwater optical wireless communications: depth dependent variations in attenuation [PDF]
Applied Optics, 2013 Depth variations in the attenuation coefficient for light in the ocean were calculated using a one-parameter model based on the chlorophyll-a concentration C(c) and experimentally-determined Gaussian chlorophyll-depth profiles. The depth profiles were related to surface chlorophyll levels for the range 0-4 mg/m², representing clear, open ocean.

Recent advances in underwater optical wireless communications
Underwater Technology: International Journal of the Society for Underwater, 2014 Abstract Optical wireless communications (OWC) are being consid-ered for use under water because sea water exhibits a win-dow of reduced absorption in the visible spectrum, particularly between 400–550nm. Recent technology has demonstrated the ability to support mid-range links (
