Time-Depth plots of regional variation

Time-Depth plots of mean and regional Variation (by year)

Mean Strait of Georgia Conditions for all years

Mean conditions in the Strait of Georgia (averaged over regions 2/3/4/6/7/8/9) for a) temperature, b) salinity, c) dissolved oxygen content, and d) chlorophyll for all years.  White lines indicate 17 °C in temperature plots, and 187 µM (6ppm) and 250 µM (8ppm)  in O2 plots. Note that the depth axis is linear in depth in the upper plots, but logarithmically scaled in the second row of plots to highlight near-surface details (Chlorophyll plots show the logarithmic depth scales in both sets).

Mean Strait of Georgia conditions by year

Mean conditions in the Strait of Georgia (averaged over regions 2/3/4/6/7/8/9) for a) temperature, b) salinity, c) dissolved oxygen content, and d) chlorophyll for each year. White lines indicate 17 °C in temperature plots, and 187 µM (6ppm) and 250 µM (8ppm)  in O2 plots. Note that the depth axis is logarithmically scaled in d) to highlight near-surface details.

Temperature by Region for All Years

Contour plots for temperature in each region for each year. Black dots at the top of each plot indicate sampling days for that region. The white line indicates 17°C. Region boundaries are given in the map at lower right.

Salinity

Contour plots for  salinity in each region for each year. Black dots at the top of each plot indicate sampling days for that region. Region boundaries are given in the map at lower right.

Chlorophyll

Contour plots for chlorophyll biomass in each region for each year. Black dots at the top of each plot indicate sampling days for that region. The depth scale is logarithmic so that more details can be seen near the surface. Region boundaries are given in the map at lower right.

Dissolved Oxygen

Contour plots for dissolved oxygen concentrations in each region for each year. Black dots at the top of each plot indicate sampling days for that region. White lines indicate  187 µM (6ppm) and 250 µM (8ppm)  limits. Region boundaries are given in the map at lower right.
