For the last few days, the scientific season is at its height and our pack ice is receiving full attention. Diversity of measures is to compare with diversity of researchers welcomed on board Vagabond. American, Estonian, English, Finn, French, all together we are sounding sea ice an its environment with CTD, icemeter, radiometers, thermometers, hygrometers, anemometers, densitometer... Some instruments are diving 100 meters below pack ice, others are climbing up to 1500 meters altitude. What a place full of life! In addition, the weather is perfect: temperature -30°C, no wind and clear sky for the last 4 days.
