Instruments

Dataset-specific Instrument Name
SAMI-CO2 pCO2
Generic Instrument Name
Submersible Autonomous Moored Instrument
Dataset-specific Description
SAMI-CO2 pCO2 and Temperature mooring time series data collected on the Buzzards Bay mooring
Generic Instrument Description
The Submersible Autonomous Moored Instrument (SAMI) measures and logs levels of dissolved chemicals in sea and fresh water. It is a plastic cylinder about 6 inches wide and 2 feet long that is self-powered and capable of hourly measurements for up to one year. All data collected are logged to an internal memory chip to be downloaded later. SAMI sensors usually are placed a few feet underwater on permanent moorings, while others on floating drifters sample the water wherever the wind and currents carry them. The instruments have been used by researchers around the globe in a variety of studies since 1999. Dr. Mike DeGrandpre, University of Montana, developed the SAMI between 1990 and 1993 during his postdoctoral work at the Woods Hole Oceanographic Institution (Woods Hole, MA, USA).

Project Information

Commercialization of Autonomous Sensor Systems for Quantifying pCO2 and Total Inorganic Carbon (MBARI)

Coverage: Northeastern Pacific Ocean, MBARI M0 mooring, 36.893N, 121.90W


ABSTRACT
The PIs propose to use the NOPP Topic 4B funding to promote commercialization of their Submersible Autonomous Moored Instrument, SAMI-CO2, a sensor developed for autonomous measurements of the partial pressure of CO2 (pCO2). Field deployments by the PI and others have demonstrated the excellent long-term stability predicted by SAMIs' well-understood theoretical response. The PIs propose to redesign the sensor to improve reliability, make it more user friendly and to implement modern electronic and manufacturing technologies. The new design will allow individual investigators to make pCO2 measurements reliably over long time periods in widespread ocean locations on many different ocean platforms.

Broader Impacts
The proposed work will not only increase the availability of autonomous pCO2 sensors but will also provide the means for quantifying total inorganic carbon through pH-alkalinity or pCO2-alkalinity calculations. The research directly addresses an important need for chemical sensors for implementing ocean observatory systems such as the IOOS with systems to determine impacts of chemical species in the oceans.
