Hospital Hole Day, September 18, 2018

On Tuesday, we went to Madison’s site, Hospital Hole, to collect water column samples from each water layer. Bobby had visited Hospital Hole for fun about a month ago and discovered two new vents that we were going to check out. The Hydrolab indicated that these two vents expel water from the same source. The vent at 77’ was covered with mats of white filamentous biofilm! (video to be uploaded). We sampled the biofilm for microscopic imaging and analysis. Our MS student, Chelsea, was also able to get in her first scientific dive! We had a flat tire on the way back to the lab, which made for a late night performing water chemistry. But thanks to the help of a couple volunteers, everything went smoothly. Overall, a long, but successful day!
