Each year we assess long-term trends in nutrients oxygen and other variables in Puget Sound, Willapa Bay and Grays Harbor. Trends are based on de-seasonalized monthly data which were averaged over the year and across stations of one of the three regions.

De-seasonalized data reveal subtle long-term trends. We generate them by subtracting a site-specific, time-averaged seasonal cycle from the dataset.
