Paper Abstract

We have investigated the possibility of using optical instruments to detect the presence of frazil ice in Arctic leads. Frazil ice was successfully detected with a transmissometer but could not be seen with scattering sensors. Field measurements were made in Arctic leads north of Alaska during the spring of 1992 as a part of the lead experiment (LEADEX). On two occasions, the temperature, salinity, and transmission signals show the presence of frazil. Because a transmissometer cannot distinguish ice from other types of particles, we present a concept for a dual wavelength absorption meter that would be able to distinguish between frazil ice and biological particles.
