The LAB60 simulation is a coupled ocean sea-ice model (NEMO) that uses grid refinement to achieve high resolution (1/60 of a degree) within the Labrador Sea. This video shows the freshwater layer thickness (in meters), relative to a salinity of 34.8, from 2005 through the end of 2018. Higher...
Competition for prey is known to narrow the trophic niche width of freshwater fishes. Upon release from interspecific competition, the niche variation hypothesis (NVH) predicts that population niche width will expand via increased inter-individual variation in resource use. I compared the...
The molecular identity of the Na+ uptake mechanism across the gills of freshwater fish has been the subject of lively debate for decades. Despite the extensive evidence for NHE mediated Na+ uptake, thermodynamic constraints on the function of NHEs at low ion concentrations and low environmental...
Numerical modelling of the Arctic and North Atlantic exchanges with NEMO: Focus on freshwater and dynamicsDownload
The Arctic is currently undergoing significant changes due to increasing anthropogenic greenhouse gases causing atmospheric warming. The impact of this warming is clearly visible in the Arctic: reduced sea-ice cover, enhanced land-ice melting, increased frequency of extreme weather, etc....
Ichnology concerns the study of interactions between organisms and both soft and hard substrates. Actualistic observation of a modern day river channel molluscan assemblage including unionid and sphaeriid bivalves and gastropods within the Saint John River, Fredericton, New Brunswick, Canada...
This thesis presents the numerical simulations related to freshwater processes within the Canadian Arctic Archipelago (CAA) using a coupled ocean and sea ice pan-Arctic model based on NEMO v3.1. In this study, two major routes for the export of Pacific water to the North Atlantic, via either...
