Residuals of the Separation of the BC Front From the Continental Shelf

The figure below shows the residuals of the latitude of separation of the BC front from the continental shelf (after a 28-days running mean), defined as the intersection between the -1000m bathymetry contour and the contour when the 10°C isotherm is 200m deep.

The monthly residuals for each month is the difference between the mean latitude for that specific month and the mean latitude for that month since October, 1992.

This figure is updated monthly using delayed-time data (about 6 month delay) and near real-time altimetry data (4 week delay) when delayed-time data are not available.

Residuals of the Southernmost Frontal Location

The figure below shows the residuals of the latitude of the southernmost frontal location (after a 28-days running mean), defined as the southernmost position of the altimeter derived 200m contour of the 10°C isotherm. These residuals were determined as described above.

This figure is updated monthly using delayed-time data (about 6 month delay) and near real-time altimetry data (4 week delay) when delayed-time data are not available.
