Underwater optical wireless communications, networking, and localization: A survey [PDF]
Ad Hoc Networks, 2019 Underwater wireless communications can be carried out through acoustic, radio frequency (RF), and optical waves. Compared to its bandwidth limited acoustic and RF counterparts, underwater optical wireless communications (UOWCs) can support higher data rates at low latency levels. However, severe aquatic channel conditions (e.g., absorption, scattering,

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.
