    Description: During Polarstern cruise ANT-XXV/5 in April/May 2009, the marine atmosphere was sampled via PTFE (Polytetrafluorethylen) tubing extending from the front of the upper deck to labs on the main deck of r/v Polarstern and then analyzed for elemental mercury in air (Hg0-air) using the same Tekran 2537A as for Hg0-water measurements. The time interval of Hg0-air measurements was 5-min with gaps of about 20 min each hour because of intermittent Hg0-water measurements. The data were checked for potential contamination during tailwind situations (relative wind speed and direction) and doubtful values were removed. The detection limit was 0.1 ng L-1 (on ANT-XXV/5: 5 times the Hg0-air values were below the detection limit).

    Description: During the Polarstern cruise ANT-XXV/1 in November 2008, surface seawater from below the ship's hull was continuously pumped through a shower head into a 20 L equilibrator bottle and drained at the bottom. Equilibrium between the supplied water and the headspace air (Hg0 equ) was achieved in about 1 h. The equilibrated air was transferred to the TEKRAN 2537A after closing the drain and elemental mercury (Hg0) was preconcentrated by amalgamation on gold traps and finally analyzed by cold vapor atomic fluorescence spectrometry. The detection limit was 0.1 ng L-1. Wind speed was taken from the Polarstern Meteorological station and surface water salinity and temperature from the thermosalinograph. Hg0 equil. was a duplicate measurement of the headspace and provided at standard reference condition of 0°C by the Tekran instrument. The value was corrected to the in situ temperature and divided by Henry's Law constant at respective sea surface water temperature.
