Living in the Hot Zone: Evaluating Stream Temperature and Juvenile Coho Salmon in Redwood Creek Using Thermal Infrared Imaging.
April 5th, 11:30 AM, CR Campus
Vicki Ozaki, Geologist, Redwood National and State Parks
Vicki Ozaki is a geologist who has worked for Redwood National and State Parks for over 20 years. She comes to College of the Redwoods on Wednesday, April 5, to present Living in the Hot Zone: Evaluating Stream Temperature and Juvenile Coho Salmon in Redwood Creek Using Thermal Infrared Imaging.. The talk begins at 11:30 am in the Physical Science building, room PS113, and will conclude by 12:30 pm. A short description of the talk follows.
Stream temperature is important to the overall health of aquatic ecosystems and can control the distribution of fish and amphibians. Redwood Creek provides habitat for coho and Chinook salmon and steelhead and coastal cutthroat trout. All of these fish require cold water to survive, but juvenile coho are the most temperature sensitive.
Thermal infrared imaging was used to measure surface water temperature along the main channel of Redwood Creek. The purpose of the project was to evaluate if summer water temperatures are a limiting factor for juvenile coho salmon in Redwood Creek. This remote sensing technology provided information on the distribution of summer water temperature along the entire length of Redwood Creek, identify warm versus cold reaches, and validate the parks monitoring locations.
