Synthesis of Current Measurements in Puget Sound, Washington. Volume 1. Index to Current Measurements Made in Puget Sound from 1908-1980, with Daily and Record Averages for Selected Measurements

摘要

Puget Sound is an estuary in northwestern Washington consisting of three branches joined near their mouths to an entrance sill zone. In turn, this zone connects to the Pacific Ocean via the Strait of Juan de Fuca. The branches consist largely of basins embraced by sill zones; the largest or Main Basin accounts for half of the Puget Sound's volume and the other half occurs mostly in three secondary basins. The estuarine flow is strongly modified by vertical mixing of surface and deep water over the sills as the water moves between the basins. To describe the characteristics of the circulation in Puget Sound, a synthesis of historical measurements of currents, water properties, and meteorological conditions has been undertaken. The study is an index to current measurements made in Puget Sound from 1908-1980, with daily and record averages for selected measurements.
