The O2 MicroOptode is designed for research within respiration, bulk and bioreactors as well as environmental and biomedical sciences
The O2 optode signal was not sensitive to variations in water flow or light exposure. However, the response time was affected by the direction of the flow. When the sensor tip was exposed to a flow from the back rather than the front, the response time increased by 37%. The meter's ...
O2 flux optode: A new sensing principle to determine the oxygen flux and other gas diffusionsBy applying a transparent test membrane of defined diffusion properties between two layers of optical chemical oxygen sensors, O2 optodes, the ... DW Lübbers,T Kster,GA Holst - 《Advances in Experiment...
Back on shore, the final O2concentration values were calculated following Bittig et al. (ref.18) from the optode, calibration and in situ pressure data that was derived from the depth where each lander deployment was made. Time stamps in the optode data were compared to the lander computer ...
The Aanderaa Oxygen Sensor measures absolute oxygen concentration and % saturation. The o2 meter can be used for streams, the deep sea, fish farms, wastewater, and polar ice areas to hydrothermal vents. Read more on the oxygen optode working principle us
The June 2015 cruise took place onboard the F.S. Alkor (GEOMAR) in the Gotland basin (Fig.1). Water samples were collected with Niskin bottles via deployment of a SeaBird CTD system. Dissolved oxygen concentration (DO) profiles were taken from the CTD optode and calibrated against DO concen...

three glass vials per station were prepared with an optode spot (Pyroscience, TROXSP5 Trace Oxygen Sensor Spot) and filled at random during aliquoting, in addition to the incubation vials. Oxygen concentrations were measured using a fibre-optic cable connected to an amplifier (Pyroscience, Firestin...
Quasi-seasonal cruise data were collected from 1998 to 2013 as part of various projects of the Biological Oceanography Group (BOG) at the Monterey Bay Aquarium Research Institute (MBARI). Dissolved oxygen data were taken with an Aanderaa optode oxygen sensor. The sensor data were averaged on 1-...
