Description:
Abstract:
The British Columbia Marine Conservation Analysis (BCMCA) is a collaborative project assembling and analyzing spatial information about Canada's Pacific Ocean. The overall goal of the BCMCA is to identify marine areas of high conservation value and marine areas important to human use. Results of the project are intended to inform and help advance marine planning initiatives in BC by providing collaborative, peer-reviewed scientific analyses based on the best ecological and human use spatial data at scales relevant to a BC coast-wide analysis.
Purpose:
The purpose of this dataset is to identify RMS tidal speeds within the Canadian Pacific EEZ to help inform the physical feature identified in the BCMCA Physical Report
Supplemental_Information:
Root Mean Square (RMS) of tidal speeds. RMS tidal speed is output from a 3-D diagnostic circulation model for the Northeastern Pacific Ocean (Dr. Mike Foreman, Department of Fisheries and Oceans). The modelled tidal speeds are barotropic, meaning density is not taken into account. The points extracted from this model were displayed and then converted into a raster.

Title: Foreman Circulation Model
Process_Step:
Process_Description:
Root Mean Square (RMS) of tidal speeds modelled over a large number of tidal cycles (RMS used to avoid near zero average velocity over tidal cycles). RMS tidal speed is output from a 3-D diagnostic circulation model for the Northeastern Pacific Ocean (Dr. Mike Foreman, Department of Fisheries and Oceans, Institute of Ocean Sciences, foremanm@dfo-mpo.gc.ca). The modelled tidal speeds are barotropic, meaning density is not taken into account.

Process_Step:
Process_Description:
RMS Tidal Speed values at the supplied nodes were exported from the Foreman Circulation Model using the export function. These points were then plotted based on the supplied coordinates and projected to BC Albers NAD83.
