These samples were taken in the Huon Estuary, offshore from Hideaway Bay. The data were collected to determine the bio-optical charateristics of this region. The data can be used for Ocean Colour sensor validation. Parameters measured are pigments and the absorption coefficients for dissolved (CDOM) particulate (ap) and detrital or non-algal (ad) components of the water column. ! references: http://www.marine.csiro.au/marq/edd_search.Browse_Citation?txtSession=6917 ! local_time_zone: [10] ! vessel: RV Explorer ! ! comments: the ag data is derived as follows; An exponential function a(lambda) = a(350).exp(-S(lambda -350)) + b was fitted to all CDOM spectra over the wavelength range 350 to 750 nm. A non-linear least-squares technique was used to fit the equation to the untransformed data. ! comments: the ad data is derived as follows; An exponential function a(lambda) = a(350).exp(-S(lambda -350)) + b was fitted to all detrital spectra over the wavelength range 350 to 750 nm. A non-linear least-squares technique was used to fit the equation to the untransformed data. ! comments: the aph data is derived as follows; Total particulate spectra were smoothed using a running box-car filter with width 10 nm, and the fitted detritus spectra subtracted. Subtracting fitted detritus spectra minimised any artefacts due to incomplete extraction of pigments ! /missing=-999 /delimiter=comma /fields=wavelength,ag,ad,aph,ap /units=nm,1/m,1/m,1/m,1/m
