Metadata (edits applied noted)

The following metadata provides comprehensive information about this dataset:

  • Title: Volume transport timeseries in the North Atlantic

  • Summary: Time series of volume transport of the Denmark Strait Overflow (DSO) at about 66 degN. The transports are calculated through interpolation of mooring data between the maximum mooring depth at 660 m and 400 m above bottom. The time period is between 1996 and 2017; the time increment is 1 hour.
