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 ... -
Sea level and circulation variability of the Gulf of Carpentaria; influence of the Madden-Julian Oscillation and the adjacent deep ocean
(American Geophysical Union, Washington, DC, 2011)The Madden-Julian Oscillation (MJO) is a significant contributing factor to intraseasonal variability in both the tropical and extratropical atmosphere and ocean. Sea level and circulation variations in the Gulf of Carpentaria ... -
Seasonal and spatial variations in methyl chloride in NW Atlantic waters
(2007-05)[1] Methyl chloride concentrations were measured in the upper 200 m of the water column of the NW Atlantic during three cruises along the same track in spring, summer and fall of 2003. Distinct seasonality was apparent, ... -
A seasonal study of methyl bromide concentrations in the North Atlantic (35 degrees-60 degrees N)
(2006-04)Methyl bromide concentrations in and over the North Atlantic were examined during spring, summer, and fall 2003. The results demonstrate that seasonality plays a great role in controlling methyl bromide fluxes from and ... -
Seasonal variability of the inorganic carbon system in the Amundsen Gulf region of the southeastern Beaufort Sea
(2011-01)During a year-round occupation of Amundsen Gulf in the Canadian Arctic Archipelago dissolved inorganic and organic carbon (DIC, DOC), total alkalinity (TA), partial pressure of CO(2) (pCO(2)) and related parameters were ... -
Sediment-water column fluxes of carbon, oxygen and nutrients in Bedford Basin, Nova Scotia, inferred from Ra-224 measurements
(2013)Exchanges between sediment pore waters and the overlying water column play a significant role in the chemical budgets of many important chemical constituents. Direct quantification of such benthic fluxes requires explicit ... -
Seismic study of the transform-rifted margin in Davis Strait between Baffin Island (Canada) and Greenland: What happens when a plume meets a transform
(2007-04)[ 1] The Davis Strait transform margin was studied using a 630-km-long wide-angle reflection/ refraction seismic transect extending from SE Baffin Island to Greenland. Dense airgun shots were recorded by 28 ocean bottom ... -
Seismic velocity structure of the rifted margin of the eastern Grand Banks of Newfoundland, Canada
(2006-11)[ 1] We present a compressional seismic velocity profile of the crust of the eastern margin of the Grand Banks of Newfoundland, Canada. This velocity model was obtained by a tomographic inversion of wide-angle data recorded ... -
A semi-analytical model of the influence of phytoplankton community structure on the relationship between light attenuation and ocean color
(1999-01)A model was developed to examine the influence of phytoplankton community structure on the relationship between diffuse attenuation and ratios of upwelling radiance. Shifts in phytoplankton communities were represented by ... -

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 ... -
The spectral effects of clouds on solar irradiance
(1998-12)Knowledge of the spectral attenuation associated with clouds is important for accurate estimates of natural irradiance at the Earth's surface. We compare spectral measurements of visible downwelling irradiance, under varying ... -
Spectrally weighted transparency in models of water-column photosynthesis and photoinhibition by ultraviolet radiation
(2004)We present a simple method for describing the influence of variable attenuation of spectral irradiance, Kd(lambda), on water-column photosynthesis and its inhibition by ultraviolet radiation (UV). The approach is based on ... -

Subtidal circulation on the Scotian Shelf: assessing the hindcast skill of a linear, barotropic model
(American Geophys. Union, 1997-11/15)Currents measured during the winter of 1985-1986 by four moorings on the inner Scotian Shelf are used to assess the hindcast skill of a three-dimensional circulation model forced by local wind stress and coastal sea level. ... -
Surface heat flux, horizontal advection, and the seasonal evolution of water temperature on the Scotian Shelf
(1994)Seasonal temperature variations on the Scotian Shelf penetrate to a depth of about 75 m. The net surface heat flux (Q) can explain about 85% of the annual cycle in the rate of change of mean temperature over this depth ... -

Three-dimensional structure of the Torngat Orogen (NE Canada) from active seismic tomography
(2000-10)The crustal velocity structure and the Moho depth of the Proterozoic Torngat Orogen, NE Canada, is determined by active seismic tomography using travel times of crustal turning rays and Moho reflections. The orogen developed ...
