Abstract
Fluorescence spectroscopy has been used to characterize and assess the vertical distribution of dissolved (DOM) and particulate matter (POM) entrapped in sea ice. Fluorescence excitation- emission of bulk particulates, performed on first-year ice and multi-year flow ice, indicated that microalgae present in different layers of the first year ice resembled typical water column phytoplankton spectra, where those in the multi-year ice samples resembled detrital spectra. Fluorescence analysis also indicated that DOM present in sea ice can be characterized by their excitation-emission in unconcentrated samples. Maximal values for DOM fluorescence were observed at shorter excitation wavelengths (250 nm - 300 nm), with an emission centered between 390 - 425 nm.
