N-ICE2015 colored dissolved organic matter absorption spectra
Colored dissolved organic matter (CDOM) absorption in seawater and sea ice. Samples filtered through 0.2 µm membrane filter. Absorbance was measured with Shimadzu UV-2401 PC spectrophotometer and 50 or 100 mm quartz cells in the wavelength range 240 to 700 nm. Absorbance was converted to absorption coefficients based on cell length. A baseline correction was applied.

- Statement
-
Datafiles are separate for samples collected from ship CTD casts or casts with the on-ice mini-rosette. The files (Matlab mat format) include, time, latitude, longitude, pressure (depth in meters), and the CDOM absorption coefficient (1/m) at every wavelength from 240 to 700 nm (461 individual wavelengths). Related data can be found in the water column biogeochemistry dataset https://doi.org/10.21334/npolar.2016.3ebb7f64.
Sea ice data from thick second-year/first-year ice and young ice in a refrozen lead in separate files. Related data and more metadata can be found at the sea ice biogeochemistry dataset https://doi.org/10.21334/npolar.2017.d3e93b31. Metadata in the mat file contains:
- sample ID
- coring site (see the above mentioned papers for more details)
- ice floe number (floe) for thick ice (see the above mentioned papers for more details); for young ice only floe 3
- date_hour: year, month, day, hour (in UTC) OR date as one cell (in UTC)
- latitude (decimals)
- longitude (decimals)
- ice thickness (in cm)
- snow depth (in cm)
- sectionbottom: ice core section bottom distance (in cm) from ice-water interface
- sectiontop: ice core section top distance (in cm) from ice-water interface
- sectiontype (for young ice): ice core section type: 1=whole core, 2=bottom part, 3=top part
- total melted volume of the ice core section (in mL) (for young ice)
- flag_cdom (for thick ice): 1=measurements with 1 cm cuvette (compromises data quality), 0=10 cm cuvette
