The seasonal cycle in the Atlantic transport to the Barents Sea during the years 1997–2001
The seasonal cycle in the Atlantic inflow to the Barents Sea is investigated by using 4-year long records from moored current meters, additional moorings of shorter duration, and hydrographic measurements. A higher transport during winter than summer is most common, but in years where the Barents Se...
