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 ... -
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 ... -
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 ... -
Absolute probability estimates of lethal vessel strikes to North Atlantic right whales in Roseway Basin, Scotian Shelf
(2012-10)Vessel strikes are the primary source of known mortality for the endangered North Atlantic right whale (Eubalaena glacialis). Multi-institutional efforts to reduce mortality associated with vessel strikes include vessel-routing ... -
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 ... -
Accelerometer tags: detecting and identifying activities in fish and the effect of sampling frequency
(2013-04)Monitoring and measuring the behaviour and movement of aquatic animals in the wild is typically challenging, though micro-accelerometer (archival or telemetry) tags now provide the means to remotely identify and quantify ... -
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 ... -

Acoustic backscatter inversion for suspended sediment concentration and size: A new approach using statistical inverse theory
(Elsevier, 2015)A new method is introduced for estimating suspended sediment concentration and grain size from acoustic backscatter observations, incorporating techniques from linearized statistical inverse theory and data assimilation. ... -
Current CaCO3 dissolution at the seafloor caused by anthropogenic CO2
(PNAS, 2018-10-29)Oceanic uptake of anthropogenic CO2 leads to decreased pH, carbonate ion concentration, and saturation state with respect to CaCO3 minerals, causing increased dissolution of these minerals at the deep seafloor. This ... -
