Satellite Data Trace Seasonal Freshwater Dispersion in Hudson and James Bays: Field and Matchup Data

Multiyear field data from Hudson and James Bays: Salinity, oxygen isotope ratio (d180), concentration of colored dissolved organic matter expressed by their absorption coefficient measured at 412 nm (aCDOM (412)), Spectral Slope of CDOM absorption.
Estimated river water, sea ice melt, and sea water fractions from in situ salinity and d180,
Matchups between in situ and satellite-derived: CDOM (multiple algorithms); salinity; river water fractions; sea ice melt fractions; and sea water fractions.
