Geoducks: Climate Storytellers of the Sea

As bivalves that live up to 180 years and with shells that can last for as long as 2000 years, geoducks (pronounced gooey ducks) are the climate storytellers of the sea. Each year, a geoduck produces calcium carbonate and protein striations in its shell much as a tree produces rings in its trunk. And as dendrochronologists read a tree’s rings for insights into the terrestrial climate of the past, sclerochronologists study the geoduck’s shells to reveal oceanic climate data from the past. By cross-referencing the growing network of marine chronologies with terrestrial chronologies from tree rings, UArizona researchers are building a more complete picture of climate patterns over time.

genuinely intersting video :) I was just curious about the geoduck and happened upon this, I hope your research is going very well. It's an incredibly interesting field, maybe it will help me in trivia one day.
