DSO Original Data Format
The Denmark Strait Overflow (DSO) monitoring provides continuous time series of dense water overflow transport through Denmark Strait, a critical component of the Atlantic meridional overturning circulation.

The dense overflows across the Greenland-Iceland-Scotland ridge constitute the most important contribution to the lower limb of the Atlantic Meridional Overturning Circulation. Among those, the Denmark Strait carries with about half of the total the largest fraction of the transport. Since 1996, the outflow of DSOW has nearly constantly be monitored with moored instruments. The University Hamburg maintains an ADCP mooring at the Denmark Strait sill up to date.
Volume transports of the overflow through Denmark Strait are captured by the two moored acoustic current profilers and hydrographic sensors at the DS1 and DS2 locations. DS1 is maintained by Hafrannsóknastofnun Marine and Freshwater Research Institute (MFRI), Iceland, and DS2 is maintained by Universität of Hamburg. Processing of the data is described by Jochumsen et. al (2017).
This dataset contains hourly time series of Denmark Strait overflow transport from 1996 to 2021 and contains an integrated quantity. It is processed data from two upward looking ADCP, but has various gaps due to missing instruments. The file format is NetCDF.
