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

Remote Real-Time Profiling of Surface Seawater CO2 at the LEO-15 Site (LEO-15)

Coverage: Rutgers University's Long-term Earth Observatory (LEO-15), Buzzards Bay Mooring and Martha's Vineyard Coastal Observatory


DeGrandpre Scientists at the Univ. of Montana, Rutgers University, and Woods Hole Oceanographic Institution will collaborate to develop an ocean CO2 profiling capability using underwater technology at Rutgers University's Long-term Earth Observatory (LEO-15) and secondly, to characterize CO2 variability at this coastal location. Work will consist of augmenting an existing profiling system so that it will acquire data from autonomous biogeochemical sensors, including a Submersible Autonomous Moored Instrument for CO2 (SAMI-CO2), O2 and light sensors, and a chlorophyll fluorometer. The profiling system will obtain time and depth-resolved PCO2 , calculated total CO2 (TCO2 ), dissolved 02, chlorophyll fluorescence and light intensity. The high resolution vertical measurements of CO2 , in combination with the other biogeochemical parameters, will provide necessary data for biogeochemical models and for estimating water column biogeochemical inventories. Real-time data acquisition and remote control of the profiler will be incorporated for testing specific questions regarding CO2 cycling. The work will determine if CO2 profiling significantly advances our ability to study and understand the marine CO2 cycle. If proven successful, the research may set the groundwork for a global scale network of in situ biogeochemical profilers to characterize ocean biogeochemical cycles.DeGrandpre, M.D., Baehr, M.M. and T.R.
