Blue Carbon Sequestration aided by pH Sensor

  1. Technology: The Transmissive pH Probes from Ocean Optics can be used with a desktop system as well as with the Jaz handheld spectrometer suite. The desktop system uses a module in the SpectraSuite software that allows for simplified calibration, convenient pH readings, customizable data logging and comprehensive exportation of data and calibration information. For field measurements, the handheld Jaz offers an easy and portable solution. Jaz’s SD card runs a script that allows you to use the factory calibration or a complete calibration. It also shows live pH values and gives you the ability to save data directly to the card.
  1. Sustainable issue: “Coastal ecosystems have been recognized as a promising reservoir for carbon storage for the future. Carbon sequestered in coastal ecosystems is commonly referred to as “Blue Carbon”. The living biomass above and below marine ecosystems absorbs atmospheric CO2 through photosynthesis, transforming inorganic carbon into organic matter. The sediments in the soil stores carbon for thousands of years after organic matter is buried. Typical blue carbon repositories include mangroves, seagrass meadows, and salt marshes”. Based on this plans are underway to re-habilitate coastal ecosystem services so that they can store carbon from the atmosphere, aiding in the slowing down of extreme climate change.

Monitoring the pH levels in and around coastal areas can identify priority areas for re-habilitation of coastal ecosystems.

  1. Technology stakeholders:

-Private companies, like Azo Sensors

-NGO and Private companies for funding

-Government agencies for regulation and implementation, i.e. NOAA

-Conservation organizations

  1. Process for implementation:

-Connect private companies like Azo Sensors with appropriate governing and conservation companies, like NOAA and Ocean Conservation, to implement monitoring

-Establish through government regulations carbon permits to include ocean blue carbon sequestration.

-Establish outreach to private companies who have been regulated to address their carbon output.
