Samples for Uranium 236 and I 129. Collected on ship CTD during cast 42 and 44 in June between 5m and 400m depth.

Microtcats and Tinytags deployed on a rope measured ocean temperature from surface down to 100 m depth.

This data set contains profiles of total attenuation and absorption measured with a Wetlabs AC-9 instrument during N-ICE2015. Scattering tube corrections of absorption data was done by subtracting the absorption values at 715nm, or in some cases 650nm. The value at 650nm was used when absorption here was lower than the absorption at 715nm. Corrections for temperature and salinity was done using coefficients from Röttgers et al (2014), with a calibration temperature of 21.9 °C, and in situ temperature from CTD casts. Some automated spike removal is performed by calculating the mean and standard deviation of a moving window along the profile, and removing values that are more than two standard deviations away from the mean. Only downcasts are used. After despiking, the 6Hz data is binned in 1m vertical bins, and averaged.
