  • Observation apparatus
    Patent number: 8202478
    Abstract: An observation apparatus can observe the temporal fluctuations of the two-dimensional distribution of oxygen concentration in the bottom sludge and also in the bottom water on the seabed at an observation site. The observation apparatus includes a pressure-resistant container main body section that has a pressure-resistant window and is hermetically sealed by a pressure-resistant container closure section, a sensor foil that contains an oxygen quenching material and is arranged at the pressure-resistant window, an excitation light source that is arranged at the pressure-resistant container main body section to irradiate the sensor foil and an image pickup apparatus that shoots the sensor foil.
