Dataset: Absorption coefficients of colored dissolved organic matter (CDOM) along US GEOTRACES North Atlantic Transect from the R/V Knorr KN199-04 cruise in the subtropical N. Atlantic in 2010 (U.S. GEOTRACES NAT project)

Optical absorption coefficient of chromophoric dissolved organic matter (aCDOM) on samples collected during Geotraces 2010 (kn199-04).

Note: These data are considered preliminary. As per PI: "CDOM data will be, unfortunately, sent as "preliminary" since our efforts to develop a satisfactory salinity correction did not yield convincing results. We will have to reanalyze the data from the stored samples. The relative magnitudes of the samples are probably OK, which is probably good, if anybody wants to use the data as a conservative tracer, but absolute magnitudes are suspect. Lots of negative values might be a good hint."
