Pro-Oceanus Systems M220 Mini CO2 Digital Loggers
Waiver type - Procurement: Nonavailability
Agency: NATIONAL OCEANIC AND ATMOSPHERIC ADMINISTRATION (1330) • Product Service Code (PSC) : 6660 | Last Modified: 08/06/2024
Procurement Summary
The GLERL requires a Mini CO2 Digital Logger that will document the impacts or potential shifts in phytoplankton species in the Great Lakes. The M220 Mini CO2 Digital Logger uses infrared detection to measure the partial pressure of CO2 gas dissolved in liquids with a range from 0-1000 ppm up to 0-100%. The instrument is a compact, lightweight, plug and play sensor; and measures total dissolved gas pressure (TDGP). The housing is rated to 6000 dbar of hydrostatic pressure, and is resistant to most corrosive liquids. The M220 Mini CO2 Digital Logger includes the following components/specifications and is the only known product capable of meeting the needs of the GLERL. The GLERL is a multidisciplinary environmental research laboratory that provides scientific understanding to inform the use and management of Great Lakes and coastal marine environments. The GLERL uses sensors to collect and monitor the CO2 and acidification levels of the Great Lakes and provide data for HAB analysis. As atmospheric CO2 increases, the availability of dissolved inorganic carbon (DIC) is shifting within aquatic systems causing the pH to drop. The GLERL requires the M22 Mini CO2 Digital Logger in order to document the impacts or potential shifts in phytoplankton species composition and abundance.
Waiver Rationale Summary
The M220 Mini CO2 Digital Loggers are used to monitor a portion of the dissolved inorganic carbon pool in water, specifically the amount of carbon dioxide (CO2), to assist in tracking acidification levels in the Great Lakes. The instruments will be used to monitor the impacts of global climate change on Great Lakes ecosystems, focusing on freshwater acidification. As atmospheric CO2 increases, the availability of dissolved inorganic carbon is shifting within aquatic systems causing the pH to drop, this is referred to as acidification. Acidification of aquatic systems is leading to an increase in the availability of CO2 within aquatic systems and reducing the stress and energy cost of carbon uptake. During bloom events, phytoplankton can quickly decrease the availability DIC (causing the pH to increase) within the system, potentially shifting the availability of carbon in favor of one type of algae over the other and potentially leading to the increase in toxic harmful algal blooms. NOAA has been given authority and has a federal mandate (HABHARCA) to monitor harmful algal bloom growth and toxicity. The required loggers will assist in the monitoring of inorganic carbon availability in bloom prone areas and the GLERL’s mission to monitor harmful algal bloom growth.
