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.

This is an umbrella (metadata-only) dataset that provides links to all individual datasets collected during the Norwegian young sea ICE expedition (N-ICE2015). The metadata is available in [DCAT (JSON-LD)](http://api.npolar.no/dataset/?q=&filter-sets=N-ICE2015&format=json&variant=ld) and as [DIF XML via OAI-PMH](http://api.npolar.no/dataset/oai?verb=ListRecords&metadataPrefix=dif&set=N-ICE2015). For humans: The NPDC dataset catalogue contains a searchable [list of N-ICE2015 datasets](https://data.npolar.no/dataset/?filter-sets=N-ICE2015).
