Description

Near-surface pCO2 time series at BML mooring, offshore of Bodega Marine Laboratory, central California coast.
Dataset was updated on 10/22/13 with data from 2012.

Methods & Sampling

Hourly pCO2 and temperature data using near surface (~1 m) Sunburst Sensors SAMI pCO2 deployed during dates:
from 05/29/2011 to 07/15/2011
from 04/14/2012 to 06/05/2012
from 08/16/2012 to 11/09/2012

Data Processing Description

QA/QC not performed, these are raw data. The dates and times displayed in the 2011 data have been corrected due to a glitch between SAMI and Excel.

BCO-DMO Edits
- Parameter names modified to conform to BCO-DMO convention
- Date reformatted to YYYYMMDD
- Time reformatted to HHMM.mm
- 'nd' (no data) inserted in blank cells
- 30 March 2015: Restricted-only access and added ISO_DateTime field.

Instruments

Submersible Autonomous Moored Instrument

Supplied Description:

Sunburst Systems Submersible Autonomous Moored Instrument for CO2 (SAMI-CO2)
Range: 150-1500 uatm
Accuracy: +/- 3 ppm based on lab calibration
Precision: < 1 ppm
From http://bml.ucdavis.edu/boon/bml_buoy.html

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.
