Crustal structure of the northern Nova Scotia rifted continental margin (eastern Canada)
(2004-09)
[ 1] The Nova Scotia continental margin off eastern Canada marks a transition from a volcanic to a nonvolcanic style of rifting. The northern ( nonvolcanic) segment of the margin was studied by a 490-km-long refraction ...
Wide-angle seismic imaging of a Mesoproterozoic anorthosite complex: The Nain Plutonic Suite in Labrador, Canada
(2000-11)
The Mesoproterozoic Nain Plutonic Suite (NPS) of Labrador (Canada), one of the largest anorogenic plutonic terranes, was studied by a refraction/wide-angle seismic experiment. Four ocean bottom seismometers and 18 land ...
New algorithms for MODIS sun-induced chlorophyll fluorescence and a comparison with present data products
(2005-02)
We discuss important sources of variability in sun-induced chlorophyll fluorescence and examine difficulties in deriving fluorescence data products from satellite imagery, with a focus on the MODerate-resolution Imaging ...
Aerobic hydrogen production and dinitrogen fixation in the marine cyanobacterium Trichodesmium erythraeum IMS101
(2008-11)
Rates of hydrogen production and acetylene reduction were measured in aerobic cultures of the marine cyanobacterium Trichodesmium erythraeum IMS101 grown in a supplemented seawater medium low in combined inorganic nitrogen. ...
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 ...
Calculation of UV attenuation and colored dissolved organic matter absorption spectra from measurements of ocean color

Predicting and verifying the intended and unintended consequences of large-scale ocean iron fertilization
(2008)
Ocean iron fertilization (OIF) is being considered as a strategy for mitigating rising atmospheric CO2 concentrations. One model for implementation is the sale of carbon offsets. Modeling studies predict that OIF has the ...
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 ...
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
(2003-11)
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 ...
Estimating the monthly pCO(2) distribution in the North Atlantic using a self-organizing neural network
(2009)
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 ...
