The CORIE observation network includes an extensive array of stations in the Columbia River estuary, and one station in the nearby coastal ocean. In addition, Clatsop Community College's M/V Forerunner serves as a mobile station of opportunity, and several cruises have been conducted over the years. CORIE also supports a limited number of remote stations in other Oregon estuaries. Station Locations Place Holder Mobile Stations The CORIE Station Map is a convenient way to become familiar with the names and locations of the various stations. At each station, variable combinations of in-situ sensors measure one or more physical properties of water or atmosphere: CT/CTD instruments: Water temperature, salinity (via conductivity) and water levels (via pressure) are measured at most stations. Multi-level measurements of temperature and salinity are available only at selected stations. (currently: Red26, Tansy Point) ADP/ADCP instruments: Profiles of velocity and acoustic backscatter are measured at five stations. Co-located scalar quantities like temperature and pressure are also measured. (Red26, Tansy Point, Am169, Am012, OGI01). Various atmospheric parameters (wind speed and direction, air temperature and relative humidity, longwave and shortwave radiation) are measured at Marsh Island. Wind and air temperature are also measured at Tansy Point and were measured for several years at Rice Island. Typical sampling intervals range from 1 to 15 minutes. Most CORIE stations allow real-time access to recent data, while others allow access to verified archived data only. The real-time telemetry network is based on spread-spectrum radio.
