“…The light detection and ranging data have a horizontal resolution of 1.8 m by 1.8 m and a vertical resolution of 0.15 m. The bathymetry was smoothed to minimize hydrostatic inconsistency associated with the use of the sigma coordinate system with steep bathymetric gradients. The associated slope-limiting ratio H/H = 0.1 to 0.2 was specified within each grid element following guidance provided by Mellor et al (1994) and using site-specific experience from Foreman et al (2009), where H is the local depth at a node and H is change in depth to the nearest neighbor. The smoothing procedure also includes adjustment of bathymetry applied to depths below 50 m in Puget Sound and near the Skagit and Padilla Bay tide flats to ensure that the individual basin and the total domain volumes remained with 1% of the original values.…”

“…As with the Broughton Archipelago model domain (Foreman et al, 2009), there are few permanent weather stations in the Discovery Islands region and no atmospheric models with sufficient resolution to capture the expected wind steering accurately along narrow passages. Twelve weather stations were deployed between October 2009 and February 2010 to augment the five already in place (Fig.…”

“…As described in Foreman et al (2009), this strategy allowed some dynamical adjustment in the channels and produced better results than treating the fresh water as point sources entering abruptly at the coastal boundary. The river discharge data were obtained from the Hydrometric Network (EC, 2010a) maintained by the Water Survey of Canada (WSC; a branch of Environment Canada) for the Homathko, Salmon and Oyster rivers while discharges for the Toba, Brem, Southgate, Estero, Phillips, Apple and Stafford rivers were estimated by comparing watershed areas to that of the Homathko (Table 2).…”

“…It can be forced with any combination of tides, wind, river runoff, surface heating and open ocean inflows, and though it has coupled nutrient-phytoplanktonzooplankton and sediment transport components, they are not employed here. This is the same code that Foreman et al (2009) used to simulate the circulation in the Broughton Archipelago region, just to the north of the Discovery Islands and that was coupled to a sea lice behaviour and dispersion model (Stucchi et al, 2011). FVCOM was also applied to simulate 3-D baroclinic circulation and vertical stratification in Placentia Bay off the east coast of Canada (Ma et al, 2012).…”

A finite volume, ocean circulation model was applied to the Discovery Islands region of British Columbia and used to simulate the three-dimensional velocity, temperature and salinity fields required by a companion biological transport model. The circulation model was initialized with a combination of climatological data and recent temperature and salinity observations, and forced with i) winds measured at seventeen weather stations, ii) the discharges from twelve rivers, and iii) five tidal constituents. A simulation for the period 1 April to 28 April 2010 was evaluated using simultaneous observations from three current meter moorings and the harmonics computed from historical measurements at twenty-four tide gauges. Though the model tidal elevations were shown to be in excellent agreement with the observations, profiles of model tidal speed versus depth generally did not capture observed vertical variations as well. Mean and low-pass filtered flow fields, though reasonably accurate near the surface, were also found to deteriorate farther down the water column. However, near-surface, model current harmonics were shown to be in reasonable agreement with those used to produce annual predictions at five sites in the Canadian Tide and Current Tables. Though the winds were not found to be a significant contributor to mean flow fields over the simulation period, tidal rectification was. Numerous residual and transient eddies that may lead to retentive regions in subsequent Lagrangian studies were predicted by the model. Future work and improvements to overcome model deficiencies are briefly outlined.RÉSUMÉ [Traduit par la rédaction] Nous avons appliqué un modèle de volume fini des courants océaniques à la région des îles Discovery en Colombie-Britannique et nous nous en sommes servis pour simuler les champs de la vélocité, de la température et de la salinité en trois dimensions, exigés par un modèle de transport biologique d'accompagnement. Le modèle de circulation a été initialisé au moyen d'une combinaison de données climatologiques et d'observations récentes liées à la température et à la salinité et il a été forcé avec les vents mesurés à 17 stations météorologiques, le débit de 12 cours d'eau et cinq composantes de marées. Nous avons évalué une simulation pour la période allant du 1 er avril au 28 avril 2010 à l'aide d'observations effectuées simultanément par trois courantomètres, et les harmoniques ont été calculées à partir des mesures effectuées dans le passé à 24 marégraphes. Bien que les hauteurs de la marée établies par le modèle concordent parfaitement avec les observations, les profils de la vitesse de la marée dans le modèle en fonction de la profondeur ne réflétaient généralement pas aussi bien les variations verticales observées. De plus, nous avons constaté que les champs de courant moyens et auxquels on avait appliqué un filtre passe-bas perdaient en précision plus bas dans la colonne d'eau bien que leur valeur près de la surface soit raisonnablement exacte. Cependant, les harmoniques des c...

“…In this study, the Finite Volume Coastal Ocean Model (FVCOM) was used. It has been applied with good results to a wide variety of ocean studies (e.g., Foreman, Czakjko, Stucchi, & Guo, 2009;Han, Ma, & deYoung, 2011;Ji et al, 2006). Unstructured grids have the advantage of resolving complex coastal geometries and regions with complex frontal systems while limiting computational load.…”

Sensitivity of the Simulated Kingston Basin—Lake Ontario Summer Temperature Profile using FVCOM

Using an unstructured grid finite volume model (Finite Volume Coastal Ocean Model (FVCOM)), numerical model simulations were generated and compared for the 2006 summer hydrography of the Lake Ontario-Kingston Basin system. Simulations are forced with surface forcing from two different sources: observations collected by Environment Canada and output generated by the North American Regional Reanalysis (NARR). Simulated temperatures are compared with observations collected during the same time period to assess the viability of the NARR dataset as a source of long-term surface forcing fluxes. Root mean square errors for vertical temperature profiles, comparisons to lake surface temperatures, and Kingston Basin current observations, indicate that using NARR data to force an FVCOM model simulates the hydrography as well as simulations forced with in situ observations. RÉSUMÉ [Traduit par la rédaction] À l'aide d'un modèle aux volumes finis à grille non structurée (Finite Volume Coastal Ocean Model (FVCOM)), nous avons généré et comparé des simulations par modèle numérique pour l'hydrographie de l'été 2006 du système lac Ontario -bassin Kingston. Les simulations sont forcées par un forçage en surface provenant de deux sources différentes : les observations recueillies par Environnement Canada et la sortie produite par le NARR (North American Regional Reanalysis). Nous comparons les températures simulées avec les observations recueillies durant la même période pour évaluer la viabilité de l'ensemble de données NARR en tant que source de flux de forçage en surface à long terme. Les erreurs-types pour les profils verticaux de température, les comparaisons avec les températures de surface du lac et les observations du courant dans le bassin Kingston indiquent que l'utilisation des données NARR pour forcer un modèle FVCOM simule l'hydrographie aussi bien que les simulation forcées par des observations in situ.
