The field phase of the World Ocean Circulation Experiment, designed to address inadequate coverage of the world ocean, was executed through international collaboration over the period 1990 to 1998. A major Canadian contribution was a dedicated program in the Labrador Sea, specifically the Atlantic Repeat Hydrography Line 7 West. Canada continues to occupy this line annually through the Atlantic Zone Off-Shelf Monitoring Program. Here, the hydrographic 1991 to 2020 climatology for stations along the line are calculated to support annual reporting on variability. Details on data coverage and a brief summary on the results are provided. Cite this data as: Layton., C., Greenan., B., Wang., Z.
