Diving Into Hook-and-Line Data

Though our spring hook-and-line surveys were cancelled, our ecological team has been busy analyzing data from previous sampling years. These graphs summarize the average biomass of fish throughout the years of sampling at Cascade Head and Cape Perpetua, which were established as marine reserves in 2014. Read More

Black Oystercatcher Study With Help From Volunteers

While the Black Oystercatcher has a conspicuous presence on our coast, little demographic information has been collected on this seabird in recent years. Portland Audubon, research partners, and volunteers conducted a statewide survey to get an updated population estimate and learn more about their distribution at marine reserve sites and along the coast. Findings from this study have recently been published. Read More

Oceanographic Sensors at Cascade Head

Watch as ODFW sets out oceanographic sensors at Cascade Head. These sensors collect data on temperature, salinity, and oxygen every hour of the day and are left in the water for several months. This helps us understand the oceanographic conditions at the marine reserve, such as when a hypoxia (low oxygen) event has occurred.
