A subpolar gyre refers to a circular ocean current that occurs in colder regions, near the poles. It is a large spinning movement of water that affects the climate and marine life in those areas. Full definition
We are reporting monthly time series of surface temperature, salinity and density in the North Atlantic subpolar gyre in 1993 — 2017 from hydrographical data collected in particular from thermosalinographs on board selected ships of opportunity. (earth-syst-sci-data-discuss.net)
