Madden-Julian Oscillation and sea level: Local and remote forcing
(American Geophysical Union, 2010-01)
The Madden-Julian Oscillation (MJO) is the dominant mode of atmospheric variability in the tropical atmosphere on intraseasonal time scales (i.e., weeks to seasons). This study examines the connection between the MJO and ...
Estimating mixed layer nitrate in the North Atlantic Ocean
(2010)
Here we present an equation for the estimation of nitrate in surface waters of the North Atlantic Ocean (40 degrees N to 52 degrees N, 10 degrees W to 60 degrees W). The equation was derived by multiple linear regression ...
Methodological Underestimation of Oceanic Nitrogen Fixation Rates
(2010-09)
The two commonly applied methods to assess dinitrogen (N(2)) fixation rates are the (15)N(2)-tracer addition and the acetylene reduction assay (ARA). Discrepancies between the two methods as well as inconsistencies between ...
Spatiotemporal variations of fCO(2) in the North Sea
(2010)
Data from two Voluntary Observing Ship (VOS) (2005-2007) augmented with data subsets from ten cruises (1987-2005) were used to investigate the spatiotemporal variations of the CO2 fugacity in seawater (fCO(2)(sw)) in the ...
Satellite observations reveal high variability and a decreasing trend in CO sub(2) fluxes on the Scotian Shelf
(European Geosciences Union, 2010-07)
We develop an algorithm to compute pCO sub(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 ...
Tropical Pacific Ocean and the Madden-Julian Oscillation: Role of wind and buoyancy forcing
(2010-05)
A global ocean circulation model is used to examine the dynamical response of the tropical Pacific Ocean to forcing associated with the Madden-Julian Oscillation (MJO). Model sensitivity experiments first reveal that ...
Air-Sea CO2 fluxes on the Scotian Shelf: seasonal to multi-annual variability
(2010)
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 ...
