Dissolved Oxygen, pH, Temperature, Salinity, and others collected via time series logging probe at Tatoosh Island, Washington from June 4, 2000 to August 23, 2010 (NODC Accession 0099812)

To understand how ocean conditions influence population and ecological community dynamics of rocky shore habitats, we initiated measurements of key physical/chemical parameters at Tatoosh Island, Washington, in June 2000, including water temperature, dissolved oxygen, pH, and salinity/conductivity. Measures were made with a Hydrolab DS4a/DS5x logging probe at half hour intervals during spring-late summer in each year. Submitted data were collected through August 2010. The probe was deployed at biweekly-monthly intervals, with cleaning and calibration done in a 12-24 hr period before probe redeployment. The probe was secured to the shoreline of Tatoosh Island, and was housed in a 5000 l tidepool separated from the ocean by a 1 wide lip at a tide height of 80 cm to assure that probe performance was not compromised by desiccation at low tide. These data form the core of analyses in Pfister et al. (L&O 2007), Wootton et al. (PNAS 2008), and Wootton and Pfister (PLoS ONE In Press 2012).
