After retrieving and cleaning the racks on July 15th, and redeploying all 6 back on the same platform on July 20th, a lot of colonization has occurred on the top discs. The Inner Harbor is back to the normal, "iced tea" color instead of a pistachio green (sulfur bacterial bloom).
Although the discs still were still dark, they were not black/gray. The dominating organisms found on the discs include the tube bryozoan and stentors. A few entoprocts, colonial ciliates, and mussels were also found around the disc.

Excellent work and observations this summer! The biofilm colonization and associated organisms tell the story reflected by the measures of water quality and weather events. The water quality and weather data alone is not enough to fully visualize the impact on organisms. Well done
