underwater Inner Harbor

July 13, 2022, 10:00 AM – 12:15 PM. Biodiversity Study, sampling BioBuggy project at the National Aquarium “floating wetlands,” location off of Pier III. Baltimore Inner Harbor.

3m below the surface of the water. Location of Pier III biodisk. “hydro-chime” biofilm sampling experiment, Dr. Eric Schott, IMET, “floating wetlands” experiment, Charmaine Dahlenburg, National Aquarium, and Stephen Bradley, underwater video, and sound. Baltimore Inner Harbor, Maryland

The videos are shot at the same location approximately a month apart. There is a stricking difference between the two video works. The first date, July 13, air temperature was around 84 degress, humdity 63% slightly overcast. There are many more critters present, less debris. The second date, August 9, air temperature was 91 degress, humidity, 94. There was much more debris in the harbor, fewer critters and less visibility. Soon after the footage was taken, there was what scientists call a turnover event. Basically, the air temperature changes drastically cuasing the water collums to exchange from the top of the oxigenated water collum to the bottom where oxegey can be much less and also contains toxic sediment and nutrients that can cause bacterial bloom that colorizes the water to a chaulky white, or greenish hue that also smells like rotten eggs. The oxigen in the water is depleated and there is a high nubmer of animals die off suddenly.
