Video - O2, pH and CO2 dynamics around a root of the salt marsh plant; Spartina anglica, during light and dark alternations

Video of O2, pH and CO2 dynamics around a root of the salt marsh plant; Spartina anglica, during light and dark alternations. The 2D distribution of O2, pH and CO2 was recorded during a light (12h)-dark (12h)-light (12h)-dark (12h) interval using the Planar optode system; VisiSens TD from PreSens - Precision Sensing GmbH, Regensburg, Germany. The 2D distribution of O2, pH and CO2 was recorded as single images at 10min intervals. Subsequently, the images were compiled to a video.
