Effect of the nonlinearity of the carbonate system on partial pressure of carbon dioxide in the oceans
Partial pressure of CO sub(2) is a nonlinear function of several seawater properties. Due to the nonlinearity in this relationship, the partial pressure of a uniform ocean would be different from that of a nonuniform ocean ... -

Effects of temperature and circulation on the population dynamics of Calanus finmarchicus in the Gulf of St. Lawrence and Scotian Shelf: Study with a coupled, three-dimensional hydrodynamic, stage-based life history model
We developed a physical-biological model for the Gulf of St. Lawrence (GSL) and Scotian Shelf (SS) by coupling a stage-based life-history model of the planktonic copepod Calanus finmarchicus to a three-dimensional ocean ... -
Enhanced ocean carbon storage from anaerobic alkalinity generation in coastal sediments
The coastal ocean constitutes the crucial link between land, the open ocean and the atmosphere. Furthermore, its shallow water column permits close interactions between the sedimentary and atmospheric compartments, which ... -
Estimating mixed layer nitrate in the North Atlantic Ocean
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 ... -
Estimating the monthly pCO(2) distribution in the North Atlantic using a self-organizing neural network
Here we present monthly, basin-wide maps of the partial pressure of carbon dioxide (pCO(2)) for the North Atlantic on a 1 degrees latitude by 1 degrees longitude grid for years 2004 through 2006 inclusive. The maps have ... -

Evidence for asymmetric nonvolcanic rifting and slow incipient oceanic accretion from seismic reflection data on the Newfoundland margin
[ 1] Prestack depth migrations of seismic reflection data collected around the Ocean Drilling Program (ODP) Leg 210 transect on the Newfoundland nonvolcanic margin delineate three domains: ( 1) extended continental crust, ... -
Evolution of orogenic wedges and continental plateaux: insights from crustal thermal-mechanical models overlying subducting mantle lithosphere
The links between an early phase of orogenesis, when orogens are commonly wedge shaped, and a later phase, with a plateau geometry, are investigated using coupled thermal-mechanical models with uniform velocity subduction ... -
Extinct spreading center in the Labrador Sea: Crustal structure from a two-dimensional seismic refraction velocity model
The Labrador Sea contains a rare example of an abandoned mid-ocean ridge where active accretion of oceanic crust ceased due to a change in the spreading geometry of lithospheric plates. Seismic refraction data were collected ... -
Extraction of tidal streams from a ship-borne acoustic Doppler current profiler using a statistical-dynamical model
We present a method for extracting the barotropic tide directly from the time-space series of horizontal velocity obtained by a ship-borne acoustic Doppler current profiler (ADCP). The method is conceptually straightforward, ... -
Fine-Scale Vertical Resolution of Chlorophyll and Photosynthetic Parameters in Shallow-Water Benthos
The vertical distributions of chlorophyll concentration and photosynthetic parameters of sediment-associated microalgae were measured with a resolution of 1 mm. Sediment and the overlying water were sampled at 3 sandy, ... -
GCM experiments on changes in atmospheric predictability associated with the PNA pattern and tropical SST anomalies
Based on results from a simple three-level quasi-geostrophic model, Lin and Derome suggested that atmospheric predictability is influenced by the Pacific/North American (PNA) pattern. In the present study, predictability ... -
Genomic islands of divergence and their consequences for the resolution of spatial structure in an exploited marine fish
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 ... -
Heat flow in the Balearic and Tyrrhenian basins, western Mediterranean
Presents the results of three detailed heat flow surveys which are used to investigate the variations of heat flow and age of the Balearic and Tyrrhenian basins in the western Mediterranean. The heat flow values are within ... -

High frequency acoustic observations of episodic mixing events in Lunenburg Bay
High frequency (0.6-5 MHz) acoustic backscatter data has been collected during the past four years (2002-2006) at Dalhousie's coastal ocean observing system at Lunenburg Bay (www.cmep.ca). Severe storm events, including ... -
Hypotheses to Explain High-Nutrient Conditions in the Open Sea
Oceanic high-nutrient, low-chlorophyll waters are characterized principally by the persistence of major nutrients at the sea surface. This condition indicates control of autotrophic production by something other than NO3 ...
