DEKADE: Dekadische Variabilität der Primärproduktione u. durch Exportproduktion im Madeira Becken

The time series from Kiel276 station at 33°N, 22°W, span from 1980 to presence, are unique world wide. In the framework of the project we will use the in-situ data from Kiel276 to investigate decadal and inter-decadal changes in the physical and biogeochemical properties and place the results into context of climate variability. The project is funded by DFG (WA2175/5-1) and runs from 7/2011 to 6/2014.
