Structured-grid ocean models facilitate downscaling in the northeast Pacific, particularly for operational regional modelling and ocean forecasting in coastal British Columbia (BC), Canada. However, the complex oceanography and rugged coastal geography of BC pose well-known challenges for such models. In this study, we apply Adaptive Grid Refinement in Fortran (AGRIF) two-way nesting within the Nucleus for European Modelling o...

The Coastal Ice Ocean Prediction System for the East Coast of Canada (CIOPS-E) was developed and implemented operationally at Environment and Climate Change Canada (ECCC) to support a variety of critical marine applications. These include support for ice services, search and rescue, environmental emergency response and maritime safety. CIOPS-E uses a 1/36° horizontal grid (~ 2 km) to simulate sea ice and ocean conditions over...

The oceanography sub-initiative of Canada’s Oceans Protection Plan was tasked to develop high-resolution nearshore ocean models for enhanced marine safety and emergency response, fitting into the multi-scale, multi-level nested operational ocean forecasting systems. For decision making on eventual 24/7 operational support, two ocean models (a structured grid model, NEMO (Nucleus for European Modelling of the Ocean); and an uns...

We used longline fishing to determine the effects of distance from the ocean, season, and short‐term variation in abiotic conditions on the abundance of juvenile bull sharks ( Carcharhinus leucas ) in an estuary of the Florida Everglades, U.S.A. Logistic regression revealed that young‐of‐the‐year sharks were concentrated at a protected site 20 km upstream and were present in greater abundance when dissolved oxygen (DO) levels...

Dwarf sperm whales ( Kogia sima ) are among the most commonly stranded yet least known pelagic cetaceans. Few studies have occurred at sea, and none have quantified temporal and spatial variation in dwarf sperm whale abundance and group size. We assessed seasonal and spatial variation in dwarf sperm whale group size and abundance off Great Abaco Island, Bahamas using surveys within a 126 km 2 study area with depths between 2 a...
