A few friends and I have been going back and forth to San Francisco Bay; in the hope of starting larger scale sampling of the bay right here.

Thibaut and Hongquan did a plankton tow late last night – and I had the pleasure of imaging some of the samples.
I also want to highlight how stable the new foldscope (v2.0) is – so I can record for hours without any focus drift.
