Tide-surge interaction off the east coast of Canada and northeastern United States
(2007-06)
[1] Sea level observations and a dynamical model are used to investigate tide-surge interaction in the coastal waters off the east coast of Canada and northern USA. The study is motivated in part by the need to improve ...
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, ...
Dichloromethane in North Atlantic waters
(2004-09)
[1] Dichloromethane is an atmospheric trace gas that has a tropospheric lifetime on the order of 5 months and has major anthropogenic sources. Evidence has been presented for an oceanic source. This paper reports measurements ...
Modeling events of sea-surface variability using spectral nudging in an eddy permitting model of the northeast Pacific Ocean
(2006-06)
[ 1] Eddies are an important part of the current system that hugs the coasts of British Columbia and Alaska. The ability of "spectral nudging'' to improve the eddy statistics determined from model simulations of this current ...
Predicting the frequency of storm surges and extreme sea levels in the northwest Atlantic
(2006-10)
[1] A 40 year hindcast of storm surges in the northwest Atlantic and adjacent shelf seas is performed using a 2-D nonlinear barotropic ocean model forced by realistic 6 hourly winds and air pressures. This hindcast is used ...
Retrieval of phytoplankton biomass from simultaneous inversion of reflectance, the diffuse attenuation coefficient, and Sun-induced fluorescence in coastal waters
(2007-06)
[1] A model has been developed to retrieve phytoplankton absorption, a proxy for phytoplankton biomass, from observations of reflectance ( R) and the diffuse attenuation coefficient (K-d) collected by moored radiometers ...
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 ...
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 ...
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 ...
Crustal structure of the ocean-continent transition at Flemish Cap: Seismic refraction results
(2003-11)
[1] We conducted a seismic refraction experiment across Flemish Cap and into the deep basin east of Newfoundland, Canada, and developed a velocity model for the crust and mantle from forward and inverse modeling of data ...
