Genomic islands of divergence and their consequences for the resolution of spatial structure in an exploited marine fish
(2013-04)
As populations diverge, genomic regions associated with adaptation display elevated differentiation. These genomic islands of adaptive divergence can inform conservation efforts in exploited species, by refining the ...
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 ...
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 ...
Direct observations of diel biological CO2 fixation on the Scotian Shelf, northwestern Atlantic Ocean
(2012)
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 ...
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 ...
Anisotropy in high-frequency broadband acoustic backscattering in the presence of turbulent microstructure and zooplankton
(2012-08)
High-frequency broadband (120-600 kHz) acoustic backscattering measurements have been made in the vicinity of energetic internal waves. The transducers on the backscattering system could be adjusted so as to insonify the ...
Acoustic scattering from density and sound speed gradients: Modeling of oceanic pycnoclines
(Published for the Acoustical Society of America through the American Institute of Physics, 2012-01)
A weak-scattering model that allows prediction of acoustic scattering from oceanic pycnoclines (and the accompanying sound speed gradients) based on hydrographic profiles is described. Model predictions, based on profiles ...
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 ...
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 ...
