Abstract. The Canadian Earth System Model version 5.0 (CanESM5.0), the most recent major of global climate model developed at Centre for Climate Modelling and Analysis (CCCma) Environment Change Canada (ECCC), has been used extensively in research providing future projections context services. Previous studies have shown that CanESM5.0 performs well compared to other models revealed several biases. To address these biases, CCCma recently initiated “Analysis Development” (A4D) activity, a...
A three-dimensional circulation model, coupled to a Lagrangian particle drift is used understand the processes leading krill transport from northwest Gulf of St. Lawrence (nwGSL) towards head Lower Estuary (LSLE), well-known site accumulation. An analysis at scale (GSL) over five years (2006 2010) evidenced four major findings. (i) There are two main seasonal patterns, one in winter–spring and summer–fall, driven by local wind forcing Cabot Strait Belle Isle. (ii) The freshwater runoff...
We use the results from eight of Earth System Models (ESMs) made available for Fifth Assessment Report Intergovernmental Panel on Climate Change to analyze projected changes in biogeochemical conditions over next 50 years northwest Atlantic. looked at using Representative Concentration Pathway 8.5 scenario 100–400 m depth range a large region and more specific locations assess relevance these outputs force regional climate downscaling model Gulf St. Lawrence. The trends dissolved oxygen...
The goal of this paper is to give a detailed description the coupled physical-biogeochemical model Gulf St. Lawrence that includes dissolved oxygen and carbonate system components, as well analysis riverine contribution for different nitrogen components. A particular attention was paid representation microbial loop in order maintain appropriate level biogeochemical components within over long term simulations. skill demonstrated using situ data, satellite data estimated fluxes from studies...
Abstract This study assessed the ability of Landsat Thematic Mapper (TM) sensor data to discriminate among three damage categories Norway spruce in Krusne Hory mountains using dichotomous logit regressions. Moderate and light stands, being most spectrally similar, were separated with 83 per cent accuracy TM1, TM4 TM7. heavy best by TM3 (accuracy=88 cent). Light classes up 95 accuracy. Ratios indices did not improve regression accuracies. The equations, when used classify damage, accurately...
The Gulf of St. Lawrence (GSL), along with the Estuary, is largest estuarine system in North America. It a biologically productive sea and an important fishing ground Canada. objectives this study are to determine how climate changes will affect primary production GSL on eastern Scotian Shelf, drivers changes. We use regional ocean model forced downscaled output Max-Planck Institute Earth System Model net under change scenario Representative Concentration Pathway 8.5 (RCP8.5). Results reveal...
Capelin (Mallotus villosus) spawning in the St. Lawrence Estuary is concentrated Upper (UE). The northwest Gulf of (NW GSL) was presented as principal nursery for capelin originating from estuary. In 2009 and 2010, we investigated abundance, distribution, size structure larvae this system, a particle tracking model used to simulate larval dispersion. There evidence retention growth Lower (LE), older were found LE by end summer. October 2009, it possible link cohorts large emergence events UE...

Abstract We report the first water‐column dissolved methane data set from Estuary and Gulf of St. Lawrence (EGSL). Per surface‐water concentration sea‐to‐air flux, upper estuary behaved like a typical shallow macrotidal estuary, while lower gulf resembled outer shelf seas ocean slopes, respectively. The EGSL emitted 166.3 (71.5–214.4) × 10 6 mol CH 4 year −1 to atmosphere, representing 0.3% (0.1%–0.4%) total emission global estuarine environments. A net production 11.7 7 was required sustain...
