During the ISPOL expedition of RV Polarstern in 2004/05 sea ice brine samples (from sackhole sampling) were routinely taken. Subsequent analyses included pH, temperature, salinity, dissolved inorganic and organic (DOC & DON) nutrients (nitrite, nitrate, ammonium, phosphate, silicate), dissolved oxygen, alkalinity, 13C of DIC, chlorophyll, Particulate organic carbon and nitrogen. ** For all details see the full metadata description at "https://doi.pangaea.de/10.1594/PANGAEA.990321"!
