Although we have been collecting Acoustic Doppler Current Profiler (ADCP) data for over two years from various locations in the Strait of Georgia, real-time plots of the data have only recently been added to the Data Plots section. Shown here is a single day of data from the Eastern Strait of Georgia site, showing (top panel) the East/West component, (second panel) the North/South component, (third panel) the Up/Down (vertical) component, and (forth panel) the average back-scatter intensity.
These data are from 2 Dec 2011. The dominant signal on this day are the strong flood tides (blue in top panel/red in second panel, associated with northwest flow, (i.e. at 17:00), and relatively weak ebb tides (10:30). Occasional faint vertical banding in the vertical velocity (third panel) is an indication of internal waves, heaving the water column up (reddish) and then down (bluish). The latest 24 hours of ADCP data are available for viewing under the Data Plots section, while both plots and numerical ADCP data since 2008 are available for download.
