Teasing that information from the largest burrowing clam in the world has never been tried — until now. Yongwen Gao, a researcher for the Makah Tribe with a doctorate in fisheries and ocean sciences, is using a technique known to only a handful of scientists on the West Coast to extract the water quality information.
Previously, Gao has used a similar biochemical analysis technique to gather information about salmon, halibut, and black cod and other species important to the Makah Tribe.
As part of a project sponsored by the state Department of Natural Resources, geoduck shells were collected from three sites in Hood Canal that have been closely monitored by the Department of Ecology for the past 16 years. Researchers from the University of Washington determined the approximate age of the clams by counting the growth rings of the shells.
Gao then analyzed the shell samples for oxygen and carbon isotopes and other water quality indicators, then compared that information with data collected by DOE.
High nutrient levels are the main cause of low oxygen in the canal today. Many thousands of fish have been killed by algae blooms that rob oxygen from the water.
The blooms are fueled by increased nutrient levels from fertilizers and leaking septic systems. To see further into the past, Gao will need to analyze many more shells. Funding for that project is being considered by the Washington State Legislature.
This helps us tie together the health of North and South central Puget Sound.
