Cutting edge technology in the Fram Strait
The Fram Strait between Greenland and Spitzbergen is the main exchange gate for water masses, sea ice and heat flux between the Arctic Basin and the sub-Arctic seas. Although major resources are invested in measurements of current and temperature in the strait, the flux estimates still have significant deficiencies and errors. New observing technologies are now under testing and preparation for use in the Fram Strait.
As part of the DAMOCLES project, a first step acoustic tomography system is to be installed in the Fram Strait in August 2008. An extended acoustic system serving both tomography and glider navigation is planned to be implemented in 2009 under the ACOBAR project (Acoustic technology for observing the interior of the Arctic Ocean). Read more about the specification of the tomography systems, the experimental plan and plans for data analysis, including data assimilation, in this paper.
