Mean ventilation age reported for 7 regions of the Atlantic based on samples collected from R/V Knorr cruises KN199-04 and KN204-01 during 2010-2011

<p>Water mass fractions and ages calculated from hydrographic and tracer data using a maximum-entropy inversion technique.</p> <p>This dataset contains the fraction of water last ventilated in a given region in a time less than or equal to 39 years ago as well as the corresponding ensemble standard deviations.</p> <p>Data File Formats:<br /> For a .csv or .tsv format of these data, use the \"Get Data\" button at the top of the BCO-DMO metadata page.&nbsp;<br /> For a Matlab file containing all of the water mass fraction data from this project, see the \"Data Files\" section of the BCO-DMO metadata page.</p>
