Station M time series study (NE Pacific) CTD data (cruises 2006-2022, surface to 4000 m depth)

<p>These datasets are from sensors mounted on remotely operated vehicle deployments (ROVs Tiburon and Doc Ricketts) to Station M (approx 4000 m) in the NE Pacific.&nbsp; Collection dates were from 2006 to 2022 as the ROV operated from the surface to the abyssal seafloor.</p> <p>The&nbsp;CTD was a Seabird SBE 21, Oxygen came from a pair of Seabird SBE 43s, Beam transmission from a Wetlabs C-Star, 25cm path, 720nm(red)&nbsp;</p> <div>21 and 43s were calibrated annually at Seabird, and the 43s were corrected a couple of times a year with bottle titration.&nbsp;&nbsp;&nbsp;</div> <div>&nbsp;</div> <div>Units:</div> <div> <table> <tbody> <tr> <td>depth (meters)</td> </tr> <tr> <td>heading (degrees)</td> </tr> <tr> <td>temperature (degrees C)</td> </tr> <tr> <td>salinity (unitless)</td> </tr> <tr> <td>oxygen (ml/l)</td> </tr> </tbody> </table> </div>
