  • Air-Sea CO2 fluxes on the Scotian Shelf: seasonal to multi-annual variability 

    Shadwick, E. H., H. Thomas, A. Comeau, S. E. Craig, et al. 2010. "Air-Sea CO2 fluxes on the Scotian Shelf: seasonal to multi-annual variability." Biogeosciences 7(11): 3851-3867.
    We develop an algorithm to compute pCO(2) in the Scotian Shelf region (NW Atlantic) from satellite-based estimates of chlorophyll-a concentration, sea-surface temperature, and observed wind speed. This algorithm is based ...

  • Direct observations of diel biological CO2 fixation on the Scotian Shelf, northwestern Atlantic Ocean 

    Thomas, H., S. E. Craig, B. J. W. Greenan, W. Burt, et al. 2012. "Direct observations of diel biological CO2 fixation on the Scotian Shelf, northwestern Atlantic Ocean." Biogeosciences 9(6): 2301-2309.
    Much of the variability in the surface ocean's carbon cycle can be attributed to the availability of sunlight, triggering surface heat flux and photosynthesis, which in turn regulate the biogeochemical cycling of carbon ...
