This page will include previous collected data on Portage Bay, as well as data collected by ERIS students in an attempt to provide a background context for the ERIS observatory.
Sediment and Water Characteristics:
The following three tables were taken from “Survey of Contaminants in Sediments in Lake Union and Adjoining Waters” by James Cubbage in 1992. The data these tables provide a baseline of many of the types of measurements ERIS will provide continuously for Portage Bay. Click on the table for a larger view.
The below two tables were taken from “Lake Union/Ship Canal/Shilshole Bay Water Quality Management Program Data Summary Report Addendum” published in 1986.
These bathymetric surveys were recently produced by Emily Cyr and Miles Logsdon and provide a sense of what the underwater topography is a the ERIS site.
