What’s with the big white boat off Emma Schmitz Memorial View Point?

We believe that this is a UW research boat, The Thomas G. Thompson, to investigate methane gas that’s bubble plumes.

“In mapping the bubble plumes, it became clear that large numbers were aligned along geologic fault zones, primarily the ones running east and west, known as the Seattle, Tacoma and South Whidbey faults. Others lined up with smaller north-south faults, but the greatest number of bubble plumes occurred where the faults intersected, such as off Alki Point in West Seattle.”
