Oxygen Data from underway system Dataset Description: <p>SO-GasEx Final Discrete Oxygen Data from underway system analyzed by Winkler Titration</p> Methods and Sampling: <p><b>Operation description:</b><br />
Discrete analysis of dissolved oxygen on ship's underway seawater line.<br />
<br />
<b>Sampling times and locations:</b><br />
Sampled all CTD casts where Niskin bottles were tripped and two pumped casts.<br />
One deep cast to 4600m, three mid-depth casts to 1500m, other casts usually to 500m or 100m.<br />
See CTD cast logs and bottle files for specific times, locations, and flask numbers for each cast.<br />
<br />
<b>Overall sampling strategy:</b><br />
Normally collected one sample from each unique depth.<br />
If multiple Niskins were tripped at a given depth, hydrography sampled only one of these.<br />
Duplicate samples collected on two Niskins per cast, usually near the O2 minimum and just under the mixed layer.<br />
A mixture of triplicates and duplicates were collected from the underway seawater line.<br />
<br />
<b>Sample collection:</b><br />
Roberta Hamme collected most of the oxygen samples.<br />
However, on casts where noble gas samples or a profile of O2/N2/Ar samples were collected, Sarah Purkey collected the discrete oxygen samples.<br />
No difference in precision was detected between the two samplers, as measured by the standard deviation of duplicate samples.</p>

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>

Specified by the Principal Investigator(s)
<p><b>Analytical method:</b><br />
Winkler titration method using Langdon amperometric detection of the endpoint.<br />
Samples preserved with 1 mL each of MnCl2 and NaI-NaOH solutions.<br />
Shaken twice and stored in dark with tap water around caps to form seal.<br />
Precipitate dissolved with 1mL H2SO4 solution and titrated with thiosulfate solution.<br />
Endpoint is detected via electrode current that is related to concentration of I3-.<br />
Normally run within 24 hours, but some samples from underway system sat for 2-3 days.<br />
3-5 KIO3 standards run at beginning of each day running samples.<br />
Blanks run in distilled water used for calculations.<br />
Seawater blanks required 2-2.5 uL more titrant than distilled water blanks.<br />
<br />
<b>Calculations:</b><br />
Final dataset calculated using distilled water blanks in keeping with official WOCE methodology.<br />
High quality seawater blanks were determined on this cruise.<br />
Data is likely of higher accuracy when calculated with seawater blanks.<br />
To convert distilled blank numbers to seawater blank numbers, simply subtract 0.530 umol/kg (micromol/kg).<br />
Saturations calculated relative to Garcia and Gordon (1992,1993) with no correction for atmospheric pressure variations.<br />

Langdon Oyxgen Titrator
Langdon Oyxgen Titrator
PI Supplied Instrument Name: Langdon Oyxgen Titrator Instrument Name: Oyxgen Titrator -Langdon Instrument Short Name:O2 titrator -Langdon Instrument Description: A Langdon Oyxgen Titrator is an amperometric oxygen titration system developed to measure dissolved oxygen in seawater. The device uses a conventional polarographic electrode in connection with chronoamperometry to overcome many of the problems limiting the performance of oxygen electrodes. Reproducibility is typically better than +/- 0.8 micromolar and essentially drift-free for several weeks. A microcomputer controls all phases of the measuring process: pulse generation, data acquisition, reduction, and storage. Software is used to correct sensor output for temperature dependence and an activity coefficient, a function of temperature and salinity, is computed to correct for salinity. (Langdon, 1984. Deep Sea Research Part A. Oceanographic Research Papers, Volume 31, Issue 11, pp. 1357-1367; Culberson and Huang, 1987. Automated amperometric oxygen titration. Deep Sea Res. 34:875-880).
