Petroff et al study the magnetotactic properties of multicellular magnetotactic bacteria from Little Sippewissett salt marsh.

Ha! Except we weren't in a brain and thankfully Donald Pleasence didn't sabotage our dive!!

If you want to pick the project up again, I'm happy to help grab a sediment core anytime, Ian!

Dive through purple sulfur bacteria 101825 lrg
YouTube video by Michael McCormick Dive through purple sulfur bacteria 101825 lrg

Delighted to share this with your students, Mark! Here is a link to a slightly higher resolution version. The white specks you see at beginning of the video are zooplankton feeding on the PSB (daphnia and copepods).

Yes! About a meter below the PSB you can catch the faint green/yellow color of the green sulfur bacteria. Just like the Winogradsky column in my window.

Diving through the purple sulfur bacteria layer of Fayetteville Green Lake with our ROV last month. This is the most intense density of PSB that I've seen in many years!
