Abstract Rivers’ damming disrupts the seasonal cycle of freshwater and nutrient inputs into the marine system, which can lead to changes in coastal plankton dynamics. Here we use a 3-D 5-km resolution coupled biophysical model and downscale it to a 400-m resolution to simulate the effect of damming the Romaine River in Quebec, Canada, which discharges on average 327 m 3 s −1 of freshwater into the northern Gulf of St. Lawrence. Model results are compared with environmental data obtained from 2 b...

Since 2002, the abundance of larvae of rainbow smelt (Osmerus mordax) and Atlantic herring (Clupea harengus) has been monitored in July in coastal nurseries (Anse Ste.-Anne (ASA) and Banc de Riviere-du-Loup (BRL)) in the Middle St. Lawrence Estuary (MSLE), Canada. The two species are spatiotemporally segregated, with smelt larvae being more abundant at the upstream, less saline site (ASA) and having an earlier hatching date. Despite these differences, the abundances of both species from 2002 to ...

A new method is developed to evaluate the wave climate in the Gulf of St. Lawrence (GSL) with the consideration of wave attenuation by sea ice. Ice concentrations outputs from a regional oceanic model are used to attenuate, in post-processing, significant wave height (H s ) time-series simulated with a parametric wave model for ice-free conditions. Reanalysis data is used to compute GSL wave climate for the 1981–2010 period with and without wave attenuation by sea ice. Outputs from two simulatio...

Abstract The contemporaneous activity and sedimentary processes in a series of inner-shelf submarine canyons located in the Lower St. Lawrence Estuary were examined using high-resolution multibeam bathymetry and backscatter data. The presence of crescent-shaped bedforms (CSBs) displaced upslope at the bottom of the canyons between 2007 and 2012 indicates that they are currently active through the remobilization of sediment by gravity flows. However, the shelf and shores of the region are charact...

Les objectifs: A l’aide des observations sur la periode 2008-2012, decrire l’evolution du pied de glace (PDG) de haut estran sur des sites choisis afin de comprendre les parametres influencant ce dernier. Ces observations servent aussi a diverses simulations; Etablir le climat des glaces de mer pour le passe recent (periode 1982-2011) et le futur (2041-2070) sur l’ensemble de l’estuaire du Saint-Laurent (ESL) et du golfe su Saint-Laurent (GSL); Etablir des relations empiriques entre les variable...

Abstract The purpose of this study was to explore the importance of hydrodynamics in the spatial distribution of a dominant calanoid copepod, Eurytemora affinis , in the middle St. Lawrence Estuary. To do this, we used a 3D numerical model of the region. We successfully compared modelled trajectories to real trajectories obtained from surface drifters. Multiple trajectories were then generated to compute finite-time Lyapunov exponents (FTLEs). A ridge of high FTLE values, which starts downstream...

We present a first attempt of simulating the sympagic and planktonic production cycles in the Hudson Bay marine system (HBS) driven by ice cover duration and local hydrodynamics with the help of a 3D coupled biological–physical model. The simulation shows a marked spatial variability of ice and planktonic production and associated carbon fluxes, suggesting the co-existence of several sub-systems in the HBS. Among these, the “low ice–high mixing” Hudson Strait sub-system is characterized by high ...
