Description	Measurement of the total scattering in the blue at 412nm, in the native format of Counts.	Measurement of the total scattering in the green at 532nm, in the native format of Counts.	Measurement of the total scattering in the red at 676nm, in the native format of Counts.	The total optical backscatter at 412nm (bb(412)) in m-1, is calculated by adding the particulate backscattering coefficient, bbp, to the backscatter coefficient of seawater, bSW, divided by two (backscatter component only). bbp is a proxy for the abundance of marine particles, including phytoplankton.	The total optical backscatter at 532nm (bb(532)) in m-1, is calculated by adding the particulate backscattering coefficient, bbp, to the backscatter coefficient of seawater, bSW, divided by two (backscatter component only). bbp is a proxy for the abundance of marine particles, including phytoplankton.	The total optical backscatter at 676nm (bb(676)) in m-1, is calculated by adding the particulate backscattering coefficient, bbp, to the backscatter coefficient of seawater, bSW, divided by two (backscatter component only). bbp is a proxy for the abundance of marine particles, including phytoplankton.	The particulate backscatter coefficient (bbp(412nm)) is derived from the total volume scattering coefficient of particles, βp and the chi factor, χ (here as a constant, 1.076). This is the scattering of particles integrated over the backwards hemisphere.	The particulate backscatter coefficient (bbp(532nm)) is derived from the total volume scattering coefficient of particles, βp and the chi factor, χ (here as a constant, 1.076). This is the scattering of particles integrated over the backwards hemisphere.	The particulate backscatter coefficient (bbp(676nm)) is derived from the total volume scattering coefficient of particles, βp and the chi factor, χ (here as a constant, 1.076). This is the scattering of particles integrated over the backwards hemisphere.	Measurement of the total volume scattering coefficient in the blue at 412nm, the native format of Counts is converted into m-1 sr-1 by correcting for dark counts and using the scale factor derived during factory calibration.	Measurement of the total volume scattering coefficient at 532nm, the native format of Counts is converted into m-1 sr-1 by correcting for dark counts and using the scale factor derived during factory calibration.	Measurement of the total volume scattering coefficient at 676nm, the native format of Counts is converted into m-1 sr-1 by correcting for dark counts and using the scale factor derived during factory calibration.	Measurement of the total volume scattering coefficient in the red at 676nm, the native format of Counts is converted into m-1 sr-1 by correcting for dark counts and using the scale factor derived during factory calibration. At 676nm, the influence of the absorption of water at this wavelength should be corrected for as light that is absorbed at 676nm cannot be scattered using the following equation: βcorrected (124°, a=aw) = βmeasured (124°, a)*e0.0391a. When an ac-s is is operational a measurement of absorption will be used, when no ac-s is available the value for a = 0m-1, noting that in areas of turbid water this is not an accurate representation of the influence of absorption on scattering.	Derived total volume scattering coefficient of particles only, βp(124°,412), where the volume scattering of seawater βSW (obtained from Zhang et al. 2009) is subtracted from the total volume scattering coefficient, β(124°,412).	Derived total volume scattering coefficient of particles only, βp(124°,532), where the volume scattering of seawater βSW (obtained from Zhang et al. 2009) is subtracted from the total volume scattering coefficient, β(124°,532).	Derived total volume scattering coefficient of particles only, βp(124°,676), where the volume scattering of seawater βSW (obtained from Zhang et al. 2009) is subtracted from the total volume scattering coefficient, β(124°,676).
