Talk: Biogeochemical North Sea Climatology


Iris Hinrichs spoke on the 50th European Marine Biology Symposium on Helgoland, September 21st -25th 2015.

Iris Hinrichs presented a climatological data set of biogeochemical parameters in the wider North Sea region (15°W-15°E, 47°N-65°N). The data set is based on a broad collection of observational data of ammonium, chlorophyll-a, nitrate, dissolved oxygen, phosphate and silicate for the time period 1960-2014. Different data centres contributed data to this collection. The data collection itself went through a thorough procedure of pre-processing (unification of data formats, identification of duplicate observations) and of elaborate quality control before 3-D time series of the biogeochemical parameters were generated.

The data set complements the hydrographical climatology of temperature and salinity for the same region (Bersch et al., 2013). Furthermore, it can be used to initialise ecosystem models and/or for validation of model results of biogeochemical numerical simulations.
