This is a quality controlled revision of nutrient (nitrate plus nitrite, nitrite, phosphate, silicate and ammonium) measurements carried out during expedition PS99.2 aboard RV Polarstern (24 June 2016 - 16 July 2016) as part of the LTER HAUSGARTEN. It had not been previously been submitted to PANGAEA because at the time of analyses, problems were encountered with the instrumentation used. After an exhaustive quality controlled assessment of the data, here we are now providing a revised version, where data has been quality flagged.

In the data, flags are as follows:=> 0 = data deemed of good quality,=> 1 = data of either unknown quality or enough information to determined quality not available,=> 4 = data that was deemed needing correction,=> 8 = data deemed of bad quality.
