CABANERA-Carbon flux and ecosystem feedback in the northern Barents Sea in an era of climate change

Principle objective:
Determine the climatic sensitivity of the dominant energetic and carbon pathways in the MIZ of the northern Barents Sea and Svalbard shelf.

Sub-goals:
-Sensitivity test an existing physically-biologically coupled 3D model
-Conduct fully integrated, seasonal process studies across the MIZ
-Use field investigations and data to improve model algorithms
-Improve the model by adding CO2 and benthos module
-Validate simulation with field results
-Investigate the impact of climate variability on C flux and ecosystem feed back
-Forcast consequences of climate change for MIZ ecosystem
2003 is the first year of the project and the main activities planned is project kick-off, sensitivity testing and validation of the excisting physical-biological coupled 3D model and the first of three cruises. During two weeks in July material will be sampled and process studies carried out to achive increased understanding of the functional responses in the northern Barents Sea ecosystem including sea ice, the pelagic and benthos, physics, chemistry and biology.
