N-ICE2015 total absorption profiles from water column
Profiles of total absorption coefficient of sea water at 440 nm with Hobilabs a-Sphere integrating sphere instrument (excluding pure water absorption). Taken coincident with SBE19+ and ISUS (nitrate sensor) profiles. AC-9 profiles were taken right after a-Sphere profiles were completed.
In situ profiles of optical properties were made from a heated tent at the ice camp several hundred meters away from the ship.

- Statement
-
Instrument was factory calibrated before and right after experiment. Data from corresponding CTD profiles were used for a temperature and salinity correction of spectral absorption data obtained with ac-9 and a-Sphere following Röttgers et al. [2014]. Absorption spectra from a-Sphere were smoothed to reduce the noise (LOESS method, Cleveland [1979]).
Data consists of 57 casts (profiles) with time, latitude and longitude and pressure (depth in meters) in the mat file. Data has be binned every 0.5 m with depth.
