Help with Wierd Earl

Several months ago there was a Weird Earl that went to a survey study on how different regions of the United States pronounce different words and what they call certain objects. I cannot locate it in the archive for some reason. Does anyone know the web address? I’m nearly certain I came across it as a weird earl on this website. Thanks

Could it be pop vs. soda?

Telsur Project?

The Harvard one?

Thanks everyone, it was actually the Harvard one I was thinking of.
