Fixed Sampling Team
Fixed Sampling Team - SeaCycler
The SeaCycler was deployed on May 22, 2016. We now have a preliminary webpage to access the data from those sensors reporting in realtime. (SeaCycler Data Page at Dalhousie).
Mobile Sampling Team - EM/APEX floats
Two EM/APEX floats were deployed in the Labrador Sea. These floats profile twice and then park at 1700 m for 10 days before the next profile. Further details, including positions and data and sample figures are available at the UVic EM-APEX Float page.
Numerical modelling Team
The underlying physical model will be the Nucleus for European Modelling of the Ocean (NEMO) numerical framework version 3.4 (Madec, 2008). It is a coupled ocean/sea ice model, including a three-dimensional, free surface, hydrostatic, primitive-equation ocean general circulation model and a dynamic-thermodynamic sea-ice model (Louvain-la-Neuve: LIM2) (Fichefet and Maqueda 1997), with an elastic-viscous-plastic (EVP) ice rheology (Hunke and Dukowicz 1997). We coupled the physical configuration with a biogeochemical model for simulation of the exchange of gases with the deep ocean. The Biogeochemistry with Light Iron Nutrient and Gas (BLING - Galbraith et al. 2010) module uses a minimal number of explicit tracers, but behaves according to a relatively complex set of nonlinear functions that approximate well-established ecosystem functionality.
Model Atmospheric Forcing
Most of the recent numerical experiment set up by the numerical modelling team is using the Canadian Meteorological Centre’s (CMC) Global Deterministic Prediction System (GDPS) Reforecasts (CGRF) dataset is a relatively high-resolution forcing dataset for ocean models (Smith et al., 2013).
This forcing dataset (surface boundary conditions; SBC) is now freely available for everyone. We are glad to propose your a mirror of it. Please send an email to pmyers_ a t _ualberta.ca to request an access.
The files are accessible via rsync, available on Linux, MacOS and Windows (via cygwin). To download the whole data set in your current folder, uses the following command: rsync -rtv rsync://<user>@knossos.eas.ualberta.ca/cgrf/ ./ You can download only a specific year by completing the link with the considered year cgrf/<year> or download only a specific date by using cgrf/<year>/yyyymodd000.
