Science is packing up!

Science is packing up!

Even if we are not released from our frozen gangue, science has to forecast these unavoidable changes.

Today, on Tara, oceanography has the scientific lion’s share. The Estonian weather mast that belongs to the University of Tartu was set down with the honours due to its rank. This means that the data on the air column up to 10 meters above Tara are no longer recorded. The mast was permanently picking up the speed of the wind at four different heights but also the temperature, the humidity and the pressure.

To summarize, there remains only a seismometer on the ice to record the future ice breaks prior to our release in the open water. The rest is called CTD (conductivity, temperature, depth). 90% of the scientific handlings are thus scrutinizing the ocean, its layers, its temperature and salinity.

C’est de toute façon ce qui pourra se faire jusqu’au bout sans casser le matériel. Vu la diminution de la banquise cette été, un nouveau record, et la dérive très rapide de Tara, ce n’est pas un mal que l’océanographie fasse durer un peu plus que le plaisir. L’évolution récente de l’océan Arctique rend ces données d’autant plus intéressantes pour le programme de recherche européen « Damoclès ». Programme auquel Tara est associé dans la cadre de l’année polaire internationale 2007-2008.     

This is what can be done up to the end without breaking the equipment. Given the reduction of the pack ice this summer, a new record, and the very swift drift of Tara, it is not bad for oceanography to pursue its quest. The recent evolution of the Arctic Ocean make this data is all the more interesting for the European Research Programme Damocles, a program to which Tara is linked in the context of the International Polar Year 2007-2008.
