Abstract
Profiles of spectral attenuation and absorption were measured in situ with a WET Labs AC-9; scattering coefficients were calculated by difference. Closure of the absorption and scattering coefficients was obtained on this limited data set for in situ and discrete sample measurements. Centimeter-scale fine structures were observed in the vertical profiles. Total absorption coefficients were dominated by the phytoplankton component. Total attenuation coefficients were dominated by scattering although the effects of strong absorption were apparent in both the attenuation and scattering spectra. The vertical structure of absorption and scattering were not spatially coherent, nor were the vertical structures of phytoplankton and non- phytoplankton absorption. The strongest spatial coherence was observed between the non- phytoplanktonic component absorption and particle scattering coefficients. The spectral absorption coefficients of the in situ phytoplankton component exhibited decreasing blue to red absorption ratios as a function of depth and spectral flattening of the blue absorption peak indicative of photoadaptation.
