ORCA Interdisciplinary Projects

State of Possession Sound

The overarching theme of ocean research at ORCA is evidenced in quarter and year long research projects.  The most extensive of these projects is the State of Possession Sound, a student designed and implemented monitoring project in the local area.  Every month, students conduct on the water sampling from the chartered vessel, The Hat Express, owned and operated by the Hat Island Community. ORCA has been conducting State of Possession Sound (SOPS) research for four years as an in-house project, designed as a way to facilitate student engagement in scientific inquiry. Students board a local vessel armed with monitoring and sampling equipment to measure temperature, salinity, dissolved oxygen, pH, chlorophyll concentration, phosphates and nitrates from various depths at five different locations. At each station, vertical and horizontal plankton tows are conducted, bird and mammal species presence and abundance are recorded, and a sediment sample is collected.

Recent partnerships with the Washington State Department of Ecology and the Port of Everett resulted in the deployment of an underwater instrument that measures temperature, salinity and dissolved oxygen every 15 minutes and transmits the data online.
