Hood Canal, located on the Kitsap Peninsula, spans over 60 miles. With breathtaking views of the Olympic Mountains and an abundance of bald eagles, it is one of the most beautiful locations in Washington State. One can find wildlife such as salmon, great blue herons, hawks, and the occasional pod of killer whales.

Naturally carved out by a glacier, Hood Canal is the deepest of the four basins in Puget Sound. Depths in Hood Canal reach up to 180 meters in some locations. Flushing rates are the lowest out of the four basins (HCDOP, 2005). It takes from six months to a year for water to exchange. This has resulted in low dissolved oxygen levels in the Hood Canal basin. Studies dating back to the 1940s show that dissolved oxygen was low in Lynch Cove. Subsequent studies, dating back to the 1950s, have shown that low dissolved oxygen levels began in the south end of the canal and are now moving north (Long, 2007). Low dissolved oxygen levels are due to both natural and anthropogenic causes such as excess nutrients from non-point sources, low circulation and flushing, total nutrient load, and seawater stratification (HCDOP, 2005).

The purpose of our study was to sample locations throughout Hood Canal. On May 11th & 12th, 2012, we surveyed Hood Canal for temperature, salinity, density, dissolved oxygen, fluorescence (Chlorophyll), transmissivity, secchi depth, nutrients, phytoplankton, zooplankton, plastics, and sediments. On this website, you will find our results.
