Sensors for Biology & Environmental Research Featured Applications Respirometry: Non-invasive Tracking of O2, pH & CO2 as Indicator for Nitrification Activity pH Fluxes at the SedimentWater Interface off the South West Coast of Africa Respirometry means measuring microbial activity indirectly, such as nitrification, which is used for biological wastewater treatment. O2, pH and CO2 are key parameters in such systems. Therefore, non-invasive O2, pH and CO2 sensor spots were used to monitor either ammonium oxidizing (AOB) or nitrite oxidizing (NOB) bacteria. Additional information could be...

FEATURED APPLICATIONS Biological Oxygen Demand Measurements: Thermokarst Slumping in Tundra Lakes Permafrost degradation often occurring directly adjacent to lakes in the high Arctic, has been associated with terrestrial inputs to the lacustrine environment. An in situ mesocosm approach was used to determine the potential impacts of permafrost degradation on basal components of the food web. Biological oxygen demand (BOD) was measured weekly in the pelagic and benthic environments with optical oxygen sensors and a Fibox 3 LCD trace. First results suggest that trophic interactions play a...
