    Development, testing, and ocean mapping application of three-dimensional baroclinic hydrodynamic ocean modeling at a variety of scales
    (University of New Brunswick, 2024-12) Alleosfour, Ahmadreza; Church, Ian
    To investigate the improvement in representing the general circulation and baroclinic condition of the Bay of Fundy and Minas Basin, two high-resolution 3D baroclinic hydrodynamic models have been developed using Finite-Volume Community Ocean Model (FVCOM). The effect of surface forcing resolution is assessed by prescribing two commonly used atmospheric forcing models in the region. The model simulations are validated against the available observations and collected Conductivity, Temperature, and Depth (CTD) data during a benthic habitat campaign in July 2018, the tidal constituents, Sea Surface Temperature (SST) data from satellite, and historical published current meter data. The models show a good agreement in capturing the tide both in the Bay of Fundy and Minas Basin and represented some improvement against the operational models in the region. In addition, the improvement in representing the baroclinic condition of the Bay both at the surface and water column is reported. The coarse prescribed surface forcing resulted in a warmer surface temperature in the Bay, while the higher resolution one generated a better agreement with the observations. Also, the model simulations have been implemented in an innovative approach to evaluate the partitioning of the hydrographic survey domain and provide insight into the multibeam echosounder depth uncertainty due to using a synthetized CTD profile, based on different criteria and limitations of hydrographic survey vessels for both Minas Basin and Saint John Harbor.
