Dissolved nutrients (NO3, NO3, NH4, PO4, Si, H2S) and dissolved and particulate oganic matter (DOC, TDN, CHLa, SPM, POC, PN, d13C) were measured on bottle samples obtained during CTD casts along transects in the NE, central and NW Black Sea during RV Maria S. Merian cruise MSM33 in November and December 2013. Dissolved oxygen and salinity and temperature data for the bottla samples were added to the dataset. Metadata are UTC of the start time of the casts, longitude and latitude, and depth.
