Modeling the generation of the Juan de Fuca Eddy Results from a Regional Ocean Modeling System
Both animations shown below are from simulations that were initialized with 3D average summer temperature and salinity climatologies and forced with average summer upwelling winds and an estuarine flow in Juan de Fuca Strait. Further details are provided in an upcoming publication in the Journal of Geophysical Research – Oceans. This research was funded by Fisheries and Oceans Canada, and the Coastal Ocean Program of the National Atmospheric and Oceanic Administration (NOAA) and the National Science Foundation (NSF) through the ECOHAB PNW (Ecology and Oceanography of Harmful Algal Blooms Pacific Northwest, http://www.ecohabpnw.org/) and ORHAB (Olympic Region HAB, http://www.orhab.org/) programs. |

Daily surface salinities (psu) and velocities over a sixty day period showing that the Juan de Fuca Eddy
originates from enhanced upwelling off Cape Flattery.

Three-dimensional salinities (psu) along the 48.42°N transect cutting across
(from east to west) Juan de Fuca Strait, the rise north of Cape Flattery,
Juan de Fuca Canyon, the eastern portion of the Vancouver Island shelf,
Tully Canyon, and the western portion of the Vancouver Island shelf.
This simulation also included tidal forcing and suggests a secondary
mechanism for transporting dense water onto the shelf. Specifically, hourly
snapshots over this one day period during spring tides show a wave-like
signal moving across the bottom of Juan de Fuca Canyon and spilling
saltier water onto the eastern Vancouver Island shelf and into Tully Canyon.
