MAPCO2 SAMI-CO2 Data Dataset Description: <p>SO-GasEx MAPCO2 Buoy - SAMI-CO2 data<br />
CO2, pH, O2, and temperature data sets collected by SAMI-CO2<br />
and SAMI-pH sensors on the MAPCO2 buoy at 6 depths.</p> Methods and Sampling: <p><b>For MAPCO2 Buoy Information See: </b><a href="http://bcodata.whoi.edu/SO-GasEx/SO_GasEx_Cruise_Report.pdf">SO-GasEx cruise report, Section 5.5.1 pgs 30-33</a> <br />
<br />
<b>Parameter names, definitions and units: </b><br />
pCO2 - Partial pressure of CO2 in seawater, units in &micro;atm.<br />
O2 - Dissolved oxygen, units in &micro;mol kg-1.<br />
<br />
<b>Sampling and Analytical Methodology: </b> <br />
Data were collected by SAMI-CO2 sensors equipped with Aanderaa model 4175 oxygen optodes mounted at 5, 19, 34.5, 50, 75, 105 m depth. All sensors were calibrated in the lab prior to deployment. Blank solutions, used to detect drift in the CO2 measurements, were run every 3.5 days. The SAMI-CO2 sensor has an accuracy 1 &plusmn;1 &micro;atm, the optodes have an accuracy of 5% (15 &micro;mol kg-1 at an in situ O2 concentration of 300 &micro;mol kg-1).<br />
<br />
CO2 and O2 data were collected every half hour, and CO2 data were found to have good agreement with shipboard data after a 4 &micro;atm was applied, and O2 data agreed well with discrete Winkler titrations (typically within 1 &micro;mol kg-1). pH data was collected every hour, and interpolated to half hour intervals. The SAMI-pH sensor has an accuracy of 0.001 &plusmn; 0.0007 pH units.<br />
<br />
The buoy was initially deployed on March 8, 2008 in a SF6/3He tracer patch, and was recovered on March 12, 2008 after it was observed to be riding too low in the water. The buoy was reconfigured, and redeployed on March 13, 2008. After the first deployment of the MapCO2 buoy the 105 m SAMI was moved up to 96 m. The ship was forced to leave the study area after the second buoy deployment due to a severe storm, and when it returned the tracer patch was dispersed. The buoy was recovered, a new tracer patch was put in place, and the buoy was deployed a third time on March 22, 2008. On March 26, 2008 the tracer patch split and the buoy, along with a small tracer patch, moved away from the main tracer patch, and was recovered on March 31, 2008.<br />
<br />
<b>Data Processing: </b><br />
CO2 data were corrected for blank solutions, and missing data points due to the running of the blanks were replaced via linear interpolation. For quality control all data were compared to shipboard measurements when they were available (i.e. the ship was in the indicator patch).<br />

Ocean Carbon and Biogeochemistry
http://us-ocb.org/
Ocean Carbon and Biogeochemistry
The Ocean Carbon and Biogeochemistry (OCB) program focuses on the ocean's role as a component of the global Earth system, bringing together research in geochemistry, ocean physics, and ecology that inform on and advance our understanding of ocean biogeochemistry. The overall program goals are to promote, plan, and coordinate collaborative, multidisciplinary research opportunities within the U.S. research community and with international partners. Important OCB-related activities currently include: the Ocean Carbon and Climate Change (OCCC) and the North American Carbon Program (NACP); U.S. contributions to IMBER, SOLAS, CARBOOCEAN; and numerous U.S. single-investigator and medium-size research projects funded by U.S. federal agencies including NASA, NOAA, and NSF.
The scientific mission of OCB is to study the evolving role of the ocean in the global carbon cycle, in the face of environmental variability and change through studies of marine biogeochemical cycles and associated ecosystems.
The overarching OCB science themes include improved understanding and prediction of: 1) oceanic uptake and release of atmospheric CO2 and other greenhouse gases and 2) environmental sensitivities of biogeochemical cycles, marine ecosystems, and interactions between the two.
The OCB Research Priorities (updated January 2012) include: ocean acidification; terrestrial/coastal carbon fluxes and exchanges; climate sensitivities of and change in ecosystem structure and associated impacts on biogeochemical cycles; mesopelagic ecological and biogeochemical interactions; benthic-pelagic feedbacks on biogeochemical cycles; ocean carbon uptake and storage; and expanding low-oxygen conditions in the coastal and open oceans.

United States Surface Ocean Lower Atmosphere Study
The Surface Ocean Lower Atmosphere Study (SOLAS) program is designed to enable researchers from different disciplines to interact and investigate the multitude of processes and interactions between the coupled ocean and atmosphere.
Oceanographers and atmospheric scientists are working together to improve understanding of the fate, transport, and feedbacks of climate relevant compounds, and also weather and hazards that are affected by processes at the surface ocean.
Oceanographers and atmospheric scientists are working together to improve understanding of the fate, transport, and feedbacks of climate relevant compounds.
Physical, chemical, and biological research near the ocean-atmosphere interface must be performed in synergy to extend our current knowledge to adequately understand and forecast changes on short and long time frames and over local and global spatial scales.
The findings obtained from SOLAS are used to improve knowledge at process scale that will lead to better quantification of fluxes of climate relevant compounds such as CO2, sulfur and nitrogen compounds, hydrocarbons and halocarbons, as well as dust, energy and momentum. This activity facilitates a fundamental understanding to assist the societal needs for climate change, environmental health, weather prediction, and national security.
The US SOLAS program is a component of the International SOLAS program where collaborations are forged with investigators around the world to examine SOLAS issues ubiquitous to the world's oceans and atmosphere.

Southern Ocean Gas Exchange Experiment
http://so-gasex.org/
Southern Ocean Gas Exchange Experiment
<p>The Southern Ocean Gas Exchange Experiment (SO-GasEx; also known as GasEx III) took place in the Southwest Atlantic sector of the Southern Ocean (nominally at 50°S, 40°W, near South Georgia Island) in austral fall of 2008 (February 29-April 12, 2008) on the <a href="http://www.moc.noaa.gov/rb/">NOAA ship <em>Ronald H. Brown</em></a>. SO-GasEX is funded by NOAA, NSF and NASA.</p>
<p>The research objectives for Southern Ocean GasEx are to answer the following questions:</p>
<ul>
<li>What are the gas transfer velocities at high winds?</li>
<li>What is the effect of fetch on the gas transfer?</li>
<li>How do other non-direct wind effects influence gas transfer?</li>
<li>How do changing pCO2 and DMS levels affect the air-sea CO2 and DMS flux, respectively in the same locale?</li>
<li>Are there better predictors of gas exchange in the Southern Ocean other than wind?</li>
<li>What is the near surface horizontal and vertical variability in turbulence, pCO2, and other relevant biochemical and physical parameters?</li>
<li>How do biological processes influence pCO2 and gas exchange?</li>
<li>Do the different disparate estimates of fluxes agree, and if not why?</li>
<li>With the results from Southern Ocean GasEx, can we reconcile the current discrepancy between model based CO2 flux estimates and observation based estimates?</li>
</ul>

Submersible Autonomous Moored Instrument
Submersible Autonomous Moored Instrument
PI Supplied Instrument Name: Submersible Autonomous Moored Instrument PI Supplied Instrument Description:Sampling and Analytical Methodology:
Data were collected by SAMI-CO2 sensors equipped with Aanderaa model 4175 oxygen
optodes mounted at 5, 19, 34.5, 50, 75, 105 m depth. All sensors were calibrated
in the lab prior to deployment. Blank solutions, used to detect drift in the CO2
measurements, were run every 3.5 days. The SAMI-CO2 sensor has an accuracy 1 ±1 µatm,
the optodes have an accuracy of 5% (15 µmol kg-1 at an in situ O2 concentration of
300 µmol kg-1).
CO2 and O2 data were collected every half hour, and CO2 data were found to have good
agreement with shipboard data after a 4 µatm was applied, and O2 data agreed well with
discrete Winkler titrations (typically within 1 µmol kg-1). pH data was collected
every hour, and interpolated to half hour intervals. The SAMI-pH sensor has an accuracy
of 0.001 ± 0.0007 pH units. Instrument Name: Submersible Autonomous Moored Instrument Instrument Short Name:SAMI 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).
