%X Inherent optical properties, namely spectral absorption coefficients of soluble and filterable (Millipore 0.22 &#181;m) particulate constituents, and beam attenuation coefficients, have been measured at 19 stations east of New Zealand, in the vicinity of the Chatham Rise. In-water spectroradiometer irradiance measurements were used to test a recent algorithm for the estimation of spectral absorption coefficients. The results suggest that the algorithm worked from the near-UV through the blue and green parts of the spectrum up to wavelengths at which Raman emission became significant (&#62;590 nm). Comparison with spectroradiometrically derived absorption suggests that calculations of absorption spectra from spectrophotometer measurements of yellow substance and particulate matter captured on filters are biased by use of a published empirical relationship for the &#8216;path amplification&#8217; factor. However, scattering coefficients obtained from the spectroradiometer data by using the algorithm were in reasonable agreement with those obtained from transmissometry and spectrophotometric data.
