VITALS
Ventilation, Interactions and Transports Across the Labrador Sea

Teams

The implementation teams will apply different sets of instrumentation and approaches that are appropriate for studying the Labrador Sea and its functionality with respect to the 'breathing' process and its climatic vulnerability.

  • Given the need to measure key physical and biogeochemical processes over the full annual cycle within the Labrador Sea, our observational program will be centered around a Fixed in-situ Sampling Team that will deploy a central mooring array incorporating innovative Canadian technology including the SeaCycler.
  • To provide spatial structure for our measurements, as well as address questions of horizontal exchange, a Mobile in-situ Sampling Team will carry out innovative experiments using robotic gliders and floats.
  • Given the key role that biological and biogeochemical processes have in controlling the 'breathing' process, a Biological Processes Team will characterize these processes and address questions about their climate sensitivity.
  • Our investigation also requires accurate measurements of the gases involved in the 'breathing process'; therefore we will also include a Gases Team to provide accurate and innovative measurements of this key aspect of our program.
  • To help place the present measurements in context and take advantage of the extensive data collected via DFO's monitoring programs, a Historical Analysis Team will use the existing observational databases and annually- to decadally-resolved geological archives to document the natural variability of carbon fluxes and ocean water properties on interannual to centennial time scales.
  • Finally, to ensure that our modern and historical observations are understood at a mechanistic level and fully exploited to improve climate representation and future evolution, we will carry out extensive numerical simulations with both physical and biogeochemical models in our Numerical Modelling Team.

Further details on each of the themes and teams are given in this section.
