Noble gas observations for ECCO model and Matlab files Dataset Description: <p>This dataset includes:<br />
1) noble gas observations used in the ECCO noble gas model. They were collected globally at sea and were analyzed by mass spectrometry.<br />
(2) model&nbsp;simulations decomposed to isolate bubble-mediated gas exchange.</p>
<p><strong>Noble Gas Observations:</strong><br />
The observation data&nbsp;is provided in MATLAB format: <a href="http://dmoserv3.bco-dmo.org/data/Noble_Gas_Modeling/NobleGasDB.mat">noblegasDB.mat (download here)</a>&nbsp;(size = 94 KB)<br />
The variables are a MATLAB table ‘NGall’ and a list of original references ‘NGprojects’<br />
The served data is provided in jgofs format with the columns slightly rearranged for database best practices.</p>
<p><strong>Global Model Simulations:</strong></p>
<p>The simulation&nbsp;file is provided in MATLAB format: <a href="http://dmoserv3.bco-dmo.org/data/Noble_Gas_Modeling/ECCOv2_NobleGases.mat">ECCOv2_NobleGases.mat (download here)</a> (size = 1 GB)</p>
<p>Noble gases and nitrogen were simulated in the Estimating the Circulation &amp; Climate of the Ocean (ECCO) global ocean state estimate utilizing a matrix-free Newton–Krylov (MFNK) scheme to efficiently compute the periodic seasonal solutions for noble gas tracers.</p>
<p>Original simulations:<br />
sim1 = diffusive gas exchange only<br />
sim2 = diffusive gas exchange and bubble injection<br />
sim3 = diffusive gas exchange and bubble exchange</p>
<p>DG = sim1<br />
IG = sim2-sim1<br />
EG = sim3-sim1</p>
<p>For each gas ‘G’ total gas concentration is calculated as Gsol(S,T) * (AG + BG + CG)</p>
<p>DG is results of the simulation with no bubbles, while IG and EG are the isolated contribution from bubble injection and bubble exchange, respectively.</p> Methods and Sampling:

An Inverse and Forward Global Modeling Synthesis of Noble Gases to Better Quantify Biogeochemical Cycles

An Inverse and Forward Global Modeling Synthesis of Noble Gases to Better Quantify Biogeochemical Cycles
<p><em>Extracted from the NSF award abstract:</em></p>
<p>The noble gases (helium, neon, argon, krypton, xenon) are dissolved in the ocean at concentrations near equilibrium with the atmosphere, have known physical properties, and are abiotic which makes them excellent tracers of the physical processes that cycle gases in the ocean. In addition, each of the gases has unique properties making them sensitive to different physical processes. For this reason, scientists from Woods Hole Oceanographic Institution and Lamont-Doherty Earth Observatory will use inverse and forward modeling of noble gases to improve our knowledge of the physical processes that control the cycle of gases such as carbon dioxide, oxygen, and nitrogen in the ocean. Specifically, they would address the following three processes: (1) parameterize bubble mediated air-sea gas fluxes from breaking waves; (2) identify the background ocean accumulation of dissolved nitrogen gas from biologically mediated denitrification in the deep ocean; and (3) evaluate the strength of the solubility pump using three ocean models. To accomplish their goal, the researchers plan to compile all available noble gas observations prior to constraining gas cycling via simulations performed using three state-of-the-art ocean circulation estimates based on the Community Earth System Model, the Geophysical Fluid Dynamics Laboratory Coupled Climate Model, and the Estimating the Circulation and Climate of the Ocean data assimilated model. From this modeling effort, the researchers will be able to interpret upper ocean oxygen measurements from autonomous sensors, constrain deep ocean denitrification, and evaluate the solubility pump which is needed to assess the anthropogenic uptake of carbon dioxide.</p>
