Abstract
Following this tradition, six years ago our laboratory built a device to do accurate measurements of the optical absorption and scattering of seawater. We were traying to fill a serious gap in the database on the optical properties of seawater in the arctic and off the coasts of Canada. The device, called NEARSCAT, was deployed at sea during several cruises. As more and more data accumulated, one fact became clear: coastal waters scatter light much more than they absorb it. In othter words, the water is foggy. Light still penetrates deeply into the seawater, but it is diffused. This means that the unconventional imaging technique of range-gated laser imaging would indeed provide a significant viewing methods in a real sea environment.
