Description

This data set includes 2-meter hourly pCO2 data collected with a Sunburst SAMI at Bowdoin Buoy in Casco Bay, Maine.

Methods & Sampling

Dataset acquisition description

pCO2 data were collected with a SAMI CO2 c0003; dissolved oxygen data were collected with an Aanderaa Optode model #3835, serial #336. For operation of SAMI CO2 see:
DeGrandpre, M.D., Hammar, T.R., Smith, S.P., and F.L. Sayles. 1995. In situ measurements of seawater pCO2. Limnol. Oceanog., 40, 969-975.

Data Processing Description

Dataset Processing Description

Data was collected at the rate of once an hour and dissolved oxygen has been corrected for temperature and salinity. Missing data or calibration runs were originally represented by a -9999 (BCO-DMO has changed -9999 to 'nd' to indicate 'no data'). BCO-DMO added ISO_DateTime_UTC column.

Submersible Autonomous Moored Instrument

Supplied Name: SAMI

Supplied Description:

Instrument Type

Generic Name: Submersible Autonomous Moored Instrument

Acronym: SAMI

Generic 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). For additional information, see URL: http://www.sunburstsensors.com/ from the manufacturer, Sunburst Sensors, LLC, 1226 West Broadway, Missoula, MT 59802.
