Measurement of bulk oxygen, pH and temperature in water tanks and of highly resolved gradients of oxygen and temperature above surfaces can be measured in situ and in the lab under controlled conditions by using optical sensors from PyroScience. Some applications of our optical sensors systems in such studies are:

  • monitor the growth of mussels at different locations along a fjord while recording the natural variability of temperature and pH (among others) to improve mechanistic models describing the performance of mussels along these gradients.
  • advancement of non-invasive, remote monitoring techniques to examine population condition with quantification of aerobic metabolic rates by using intermittent respirometry,
  • measurement of oxygen fluxes between the sediment and the water column to investigate impact of invasive mussel species on benthic ecosystem functioning
  • oxygen uptake rates to investigate the response of intertidal mussel to disturbances
  • oxygen consumption measurements (in respirometric chambers) to investigate the performance under different aquaculture conditions and to predict effective aquaculture
  • experiments to investigate effects of intermittent hypoxia on cell survival and inflammatory responses in intertidal marine bivalves
  • investigation of the impact of pollutants on marine bivalves via oxygen uptake measurements
  • effects of acidification, hypoxia, and thermal stress on growth, respiration, and survival of bivalves
  • respirometry to explain species distributions related to environmental variables
  • investigation of oxygen concentration in the mantle cavity of starved and fed mussels to understand the bioenergetic implications of the valve opening-closing mechanism
  • metabolic cold adaption and aerobic performance along a temperature gradient investigated
  • climate change effects on the ecophysiology and ecological functioning of an offshore wind farm artificial hard substrate community

Sensor spots (oxygen, pH, temperature) from PyroScience feature non-invasive measurements in transparent vessels with contactless read-out from the outside through the vessel wall, and can be used for closed chamber incubations / respirometry. Fiber-optic retractable micro- and minisensors feature ultra-fast response times and high spatial resolution, specially suited for microprofiling above sediment or mussel surfaces. All oxygen sensors from PyroScience can be read-out with our multi-channel PC-operated FireSting-O2, multi-analyte meter FireSting-PRO (also in combination with our optical pH sensors), or stand-alone with our pocket oxygen meter FireSting-GO2.

For underwater measurements at in situ conditions, we offer our underwater loggers AquapHOx in combination with a broad range of underwater sensors (with -SUB connector) like miniprobes for O2 and pH, minisensors for oxygen and temperature and microsensors for oxygen.
