(2006) Macro Through Clear Water 2

Another project for same scientist below, this time for a Canon G5 digital camera in an existing Ikelite housing and strobe. The clear water tank is sized to include a glass front port for scratch-resistance. It also has a mount on the top front edge to hold the unit steadily against a glass plate embedded in the ocean floor. The glass is placed at the edge of sea grass beds, such that the growing root tips press against the glass. When photos are needed to document the root tip growth, a hole is scooped out of the sand in front of the glass, and this system is placed in contact with the glass plate. Because the scooping process makes swirls of sand in the water, the clear water inside the tank allows clear imaging of the root tips.
