TRANSDRIFT IV

« back

 

The TRANSDRIFT IV expedition took place from May 14 to June 17, 1996. The Lena-Nordenskiold station in the Lena Delta served as base camp for the 17 German and Russian scientists who took part in the expedition. Research areas were the region off the northern and eastern Lena Delta, the Lena Delta itself and the Laptev Sea polynya. To reach the research area off the Lena Delta, a helicopter MI 8-2 took the scientists onto the ice where they carried out their stations. The research focused on the period of the most rapid environmental change during the spring breakup of the Lena River. The main scientific objectives are:

  • the influence of the river breakup on the environment
  • the influence of river discharge on sediment entrainment into sea ice
  • sediment transport of the Lena River before breakup, during breakup and after breakup
  • the quality and quantity of terrigenous organic carbon flux from the Lena River into the Laptev Sea and its importance for the carbon budget
  • trace element patterns within the suspended and dissolved load of the Lena River during the first phase of the spring flood
