Pumping of nutrients to ocean surface waters by the action of propagating planetary waves

Article Abstract:

Research is presented concerning the influence of 1,000-kilometer-scale planetary waves in the supply of nutrients from the ocean floor to the surface water. The increased levels of primary productivity are discussed.

Decreasing overflow from the Nordic seas into the Atlantic Ocean through the Faroe Bank channel since 1950

Article Abstract:

The volume flux of the Faroe Bank channel overflow has decreased by at least 20% compared with 1950. The implications of this decrease depend on the behaviour of the other overflow sources.
