Float Data

SOCCOM Float Data

The raw and adjusted biogeochemical data for all SOCCOM floats are made freely available to the public in real time via our interactive map,  SOCCOMViz (a data portal developed and hosted by MBARI), or FTP.  SOCCOMViz users can either use the interface to view and create plots of the SOCCOM data or download tab-delimited, ASCII text files in OceanDataView format (see instructions below). Work is also currently underway to integrate the SOCCOM biogeochemical data into the Argo data stream. Contact us for help in accessing or using the data, and visit our observations page for detailed information on our observational program.

Authors using SOCCOM float data should acknowledge that "Data were collected and made freely available by the Southern Ocean Carbon and Climate Observations and Modeling (SOCCOM) Project funded by the National Science Foundation, Division of Polar Programs (NSF PLR -1425989), supplemented by NOAA and NASA."

SOCCOM Float Data Resources




How to access the SOCCOM float data:

Interactive Map and Data Selection Data
Use our interactive map to view float locations and trajectories and click to download raw and QC'd data.

All of the SOCCOM data are available on the web at the SOCCOMViz web page: http://soccom.princeton.edu/soccomviz.php. You can plot the data for any float on SOCCOMViz or you can download the whole file by selecting the link for “Float List and Link to Complete ASCII Data Files”. Once there, pick the QC’d files – these are files where the data has been quality controlled.

Data Snapshots
Download .zip files containing snapshots of all SOCCOM and UW/MBARI floats taken on the date in the file name. LowRes files are 30 Mbytes and only have data at the depths where chemistry is sampled. HiRes files have CTD and some chemistry data at 2 m resolution in the upper 1000 m of the profile. Those archives are about 100 Mbytes.

Automated access
If you want automated access with Matlab, or Python…. it’s a bit more complicated because the Princeton web site really points to a web site at MBARI (http://www.mbari.org/SOCCOM) and the PU site is hiding a redirect. For software access the URL to all the 9095 data is


Click that link and a tab delimited, ASCII text file will download.  That file is formatted as an ODV (Ocean Data View) spreadsheet.  ODV is freeware designed for viewing oceanographic data and it works very well.  Find it at http://ODV.awi.de.  Once you download the text file, it can be dragged on to the ODV icon on your desktop. 

Instructions for accessing low and high-resolution data files are available here.

Finally, for more background information on the data, you can view a webinar by Ken Johnson on "The QC/data adjustment process for SOCCOM sensors: what you should know when using the data."
