Model analysis and highlights


The image below is a snapshot of sea surface salinity in mid-May, 2006, highlighting the fresh waters input by the regions' major rivers.


ctdhists Figure. (a–c) Histograms (% of total CTD casts) of DeltaS (psu) grouped by region, Puget Sound, the Strait of Juan de Fuca and Strait of Georgia, and off of coastal Washington and the Columbia River. DeltaS is the difference between the observed and modeled mean S. (d–f) Same as in a–c, but for differences in DeltaS (psu), which is the mismatch between the difference of the top and bottom layer salinities of the model and observations. (g–i) Same as a–c, but for |DeltaZs| (m), which is the difference in pycnocline depths (Zs) observed observationally and calculated by the model. Note that the Straits region was commonly unstratified. See figure here for examples of how these stats were calculated.

1) Figure. Mean residence time (days) of Puget Sound subbasins. These are calculated using the mean landward exchange flow (and the volume of each subbasin) over the year long 2006 model run. Red lines mark the sections where exchange flow was calculated, while black lines delineate each subbasin.

2) Figure. Mean salinity along a section from outside Admiralty Inlet through Main Basin and over Tacoma Narrows into South Sound. See the validation against those obs here.

3) Figure. Snapshot of surface salinity over the full model domain and a zoom-in on Puget Sound taken from early July, 2006.
