Data from the OSNAP moorings, gliders and floats will be made publicly available no later than two years after the data are collected.  Please refer to the OSNAP data management plan for more details regarding OSNAP data policy and management plan.  Before the use and publication of any OSNAP data, users are strongly encouraged to read the full OSNAP data policy. We draw your attention to the following excerpts from that policy:

  • Any person making use of OSNAP observational data and/or numerical results must communicate with the responsible investigators at the start of the analysis and anticipate that the data collectors will be co-authors of published results.
  • In cases where investigators choose not to be co-authors on publications that rely on their data, the parties responsible for collecting the data and the sponsoring funding agencies should be acknowledged, including reference to any relevant publications by the originating authors describing the data sets and a reference to the data set itself using its DOI.
  • OSNAP data are intended for scholarly use by the academic and scientific community, with the express understanding that any such use will properly acknowledge the originating investigator.

The project scientists would appreciate it if you would add the following acknowledgment to any publication that uses this data: OSNAP data were collected and made freely available by the OSNAP (Overturning in the Subpolar North Atlantic Program) project and all the national programs that contribute to it (

Derived data

[1] Data from the full OSNAP array for the first 21 months (31-Jul-2014 to 20-Apr-2016) have been used to produce the 30-day mean MOC, MHT and MFT time series across the whole section, as well as the gridded property fields.  The DOI for this derived data is: 10.7924/r4z60gf0f  [download]

  • Note: The gridded property fields at OSNAP will be updated in the summer of 2019 based on improved interpolation methodology.

[2] Additional OSNAP data products for the first 21 months are as follows.

  • MOC, MHT and MFT time series across the OSNAP West and OSNAP East sections, along with uncertainty.  [download]
  • Streamfunction in potential density space, based on 30-day averaged measurements.  [download]
