Bill Hamner wipes water drops from the front of his traveling planktonkreisel. The black wings (on either side) shield the viewer from the glare of the yellow-handled lights mounted behind them. The wings fold over the front panel to protect it when it is packed for travel. The water level is half way up the chimney above the viewing chamber. Bill’s planktonkreisel design is explained in detail in the article, Hamner, W. M. 1990. "Design developments in the planktonkreisel, a plankton aquarium for ships at sea." Journal of Plankton Research, vol. 12: 397-402. Image courtesy of 2007: Exploring the Inner Space of the Celebes Sea.
